One thing you are going to want is a variety of faces that you can use for your system.

You could, perhaps, find and possibly pay hundreds of people to have their face enrolled in the system. Alternatively, you could look at some of the existing facial recognition and facial detection databases that fellow researchers and organizations have created in the past. Why reinvent the wheel if you do not have to! Here is a selection of facial recognition databases that are available on the internet. There are different rules and requirements when it comes to the usage of each of these databases.

In particular, most of these databases are only available for non-commercial research purposes.

Make certain that you read the terms of use for any database you intend to use. In most cases they will be shown on, or linked to, the database's webpage.

Many of these databases have specific requirements in regards to referencing. It currently comprises frames covering 17 people. These were recorded using Kinect for both real access and spoofing attacks. Each frame consists of a depth image, the corresponding RGB image and manually annotated eye positions with respect to the RGB image. The data was collected in 3 different sessions from the subjects. Five videos of frames were captured for each session.

The recordings were done under controlled conditions and depict frontal view and neutral expression. This database was created with a 3D acquisition system based on structured light.

The facial surface was acquired as a set of 3D coordinates using a projector and a camera. This database contains 10, natural face photographs and several measures for 2, of the faces, including memorability scores and computer vision and psychology attributes. The database includes a software tool that allows you to export custom image sets from the database for your research.

It contains over 4, color images of people's faces 70 men and 56 women. The images are frontal view faces depicting different facial expressions, illumination conditions, and add-ons like sunglasses and scarves. The pictures were taken under strictly controlled conditions. There were no restrictions placed on clothes, glasses, make-up or hair style.

There are ten different images of each of 40 distinct subjects. All the images were taken against a dark plain background.

The subjects are in an upright, frontal position.A facial expression database is a collection of images or video clips with facial expressions of a range of emotions. Well-annotated emotion -tagged media content of facial behavior is essential for training, testing, and validation of algorithms for the development of expression recognition systems. The emotion annotation can be done in discrete emotion labels or on a continuous scale.

However, some databases include the emotion tagging in continuous arousal-valence scale. In posed expression databases, the participants are asked to display different basic emotional expressions, while in spontaneous expression database, the expressions are natural. Spontaneous expressions differ from posed ones remarkably in terms of intensity, configuration, and duration. Apart from this, synthesis of some AUs are barely achievable without undergoing the associated emotional state.

Therefore, in most cases, the posed expressions are exaggerated, while the spontaneous ones are subtle and differ in appearance.

Retrieved PP 99 : 18β€”Facial coding is the process of measuring human emotions through facial expressions. With facial expression analysis you can test the impact of any content, product or service that is supposed to elicit emotional arousal and facial responses. One of the strongest indicators for emotions is our face. Computer-based facial expression analysis mimics our human coding skills quite impressively as it captures raw, unfiltered emotional responses towards any type of emotionally engaging content.

These expressed emotional states are detected in real time using fully automated computer algorithms that record facial expressions via webcam.

EyeTech VT3 Mini. Smart Eye Aurora. Tobii Pro Nano. Tobii Pro XThe ability to communicate is one of the core aspects of human life. For this, we use not only verbal but also nonverbal signals of remarkable complexity. Among the latter, facial expressions belong to the most important information channels. Despite the large variety of facial expressions we use in daily life, research on facial expressions has so far mostly focused on the emotional aspect.

Consequently, most databases of facial expressions available to the research community also include only emotional expressions, neglecting the largely unexplored aspect of conversational expressions. To fill this gap, we present the MPI facial expression database, which contains a large variety of natural emotional and conversational expressions. The database contains 55 different facial expressions performed by 19 German participants.

Expressions were elicited with the help of a method-acting protocol, which guarantees both well-defined and natural facial expressions. The method-acting protocol was based on every-day scenarios, which are used to define the necessary context information for each expression. All facial expressions are available in three repetitions, in two intensities, as well as from three different camera angles.

A detailed frame annotation is provided, from which a dynamic and a static version of the database have been created. In addition to describing the database in detail, we also present the results of an experiment with two conditions that serve to validate the context scenarios as well as the naturalness and recognizability of the video sequences. Our results provide clear evidence that conversational expressions can be recognized surprisingly well from visual information alone.

The MPI facial expression database will enable researchers from different research fields including the perceptual and cognitive sciences, but also affective computing, as well as computer vision to investigate the processing of a wider range of natural facial expressions.

Over the last decades, perceptual and cognitive studies have repeatedly shown that humans are remarkably good at recognizing face information like gender, age, identity and facial expressions. Facial expressions are special inasmuch as they constitute the only information in the face that - besides mouth movements for visual speech - rapidly and constantly changes in a variety of complex ways.

We are, however, easily able to tell different expressions apart within only a short glance. Moreover, in order to extract the correct meaning of the different types of facial expression, we do not necessarily need to know the person; that is, facial expression processing seems largely invariant to facial identity [1][2]but see also [3] β€” [5].

Facial Expression Processing Study - Ketrina Sly

With applications not only in the perceptual and cognitive sciences, but also in affective computing and computer animations, it is not surprising that facial expression research has gained lot of attention over the last decades.

Compared to other species, humans have developed highly sophisticated communication systems for social interactions. InBridwhistell demonstrated that during a typical communication, the verbal components convey one-third and the non-verbal components two-thirds of social meaning [6]. In addition to body gestures, facial expressions are one of the main information channels in non-verbal interpersonal communication [7].

Given their importance for non-verbal communication, facial expressions contain a dual aspect: they carry emotional meaning, and they also serve as a communicative information channel. Interestingly, despite this dual aspect, expressions of emotion are by far the most well-studied component of facial expressions and thus represent the aspect that is best understood [11] β€” [13].

Although emotional expressions represent an individual's internal state, it is assumed that they also partly arise through interaction with others [20]. Hence, emotional expressions also have an important social function in interpersonal communication [21]. Despite the strong communicative aspect of facial expressions, however, there is a tendency to equate facial expressions solely with emotional expressions [22].

The following lists several more encompassing definitions of the different classes of facial expressions that help to stress their complex, dual nature: Fridlund, for example, differentiated facial expressions into three different classes: 1 purely reflexive facial postures and movements, 2 apparently emotional expressions, and 3 paralinguistic or communicative facial expressions including, for example, a confirming head nodding, hence these expressions are related to speech [9].Emotion Technology Automotive Market Research.

To be precise, we have now gathered 5, face videos, for a total of 38, hours of data, representing nearly 2 billion facial frames analyzed. This global data set is the largest of its kind β€” representing spontaneous emotional responses of consumers while they go about a variety of activities.

To date, the majority of our database is comprised of viewers watching media content i. In the past year, we have expanded our data repository to include other contexts such as videos of people driving their carspeople in conversational interactions and animated gifs.

Transparency is really important to us at Affectiva, so we wanted to explain how we collect this data and what we do with it. Essentially, this massive data allows us to create highly accurate emotion metrics and provides us with fascinating insights into human emotional behavior. We have now gathered 5, face videos for a total of 38, hours representing about 2 billion facial frames analyzed. Affectiva collects these face videos through our work with market research partners, such as Millward Brown, Unruly, LightspeedAdded Value, Voxpopme and LRW, as well as partners in the automotive, robotics and Human Resources space.

As a matter of fact, we have already analyzed over 4. It is important to note that every person whose face has been analyzed, has been explicitly asked to opt in to have their face recorded and their emotional expressions analyzed. People always have the option to opt out β€” we recognize that emotions are private and not everyone wants their face recorded. In addition, data collection is anonymous, we never know who the individual is that the face belongs to. The data is representative of people engaging in an activity, such as watching content, wherever they are in the world β€” at their kitchen table in Bangkok or their couch in Rio de Janeiro.

The face videos also represent real, spontaneous facial expressions: unfiltered and unbiased emotions in reaction to the content these folks are watching or the thing they are doing. Also, this data captures challenging conditions, such as variations in lighting, different head movements, and variances in facial features due to ethnicity, age, gender, facial hair and glasses. There are other data sets available that are often developed in academic settings, and almost always collected in lab environments with controlled camera and lighting conditions.

Frequently these academic data sets introduce bias because test subjects are often from the student body and represent a certain demographic e. When you train and test against these posed datasets your accuracy may be high, but real world performance is poor due to the biased data and thus biased software that has been created.

As mentioned, we have gathered this data in over 75 countries.

This is important because people do not look the same around the world: there are differences in age, gender and ethnicity - and our data is representative of those demographics and cultural diversity. As we are a US-headquartered company, it can be easy to assume most of our data comes from North America or Western Europe. That is not the case. In fact, this is the top 10 of countries we get the most videos from:. This is in contrast to more individualistic, western countries like the US, where people often amplify their emotions, especially in group settings.

With this global data we can train our algorithms for this so we are uniquely able to identify nuanced and subtle emotion with high accuracy.

Our science team has built a robust infrastructure using machine learning and deep learning methodologies that allow us to train and test our algorithms at scale.The first of many more face detection datasets of human faces especially created for face detection finding instead of recognition :.

Therefore, several additional feature points have been marked up, which are very useful for facial analysis and gesture recognition. This data is also available for public download here. Many other face databases are available nowadays. The current trend is to recognize faces from different views, under varying illumination, or along time differences aging. Here are some especially useful for testing face detection performance:. Researchers, I need your help on this Bao Face Dataset.
