At&t face database download

The following is a directory of databases containing face stimulus sets available for use in behavioral studies.

The benchmarks section lists all benchmarks using a given dataset or any of its variants. We use variants to distinguish between results evaluated on slightly different versions of the same dataset. All the images were taken against a dark homogeneous background with the subjects in an upright, frontal position with tolerance for some side movement. The size of each image is 92x pixels, with grey levels per pixel. Stay informed on the latest trending ML papers with code, research developments, libraries, methods, and datasets.

Each image is converted to a feature vector i. But using Neural networks or SVM on a data with a feature vector of that size will increase the computational a lot. So, dimension reduction techniques like PCA were used to reduce the dimensions or bring latent factors from large data. We can also call them Eigen faces as a mean profile for all the images is constructed first and then we take the top k faces that can identify the uniqueness of all images. Each image can be represented as a combination of these eigen faces with some error, but that is very minimal that we cannot observe much differene between the two. Skip to content.

The database consists of images of 40 distinct subjects, each in 10 different facial positions and expressions. I had been interested in whether a particular statistical model could recover the 'true' partition in these data, or isolate images of distinct subjects, using only the image data. Each image is 92 x pixels in dimension, taking black-and-white integer values in the 8-bit range 0 to We can look to data-squashing to help here. Actually, I'm not sure the term 'data-squashing' was intended for methods like PCA, but it seems appropriate to me. Principal components analysis PCA was used to reduce the dataset dimensionality. PCA finds a linear transformation of high-dimensional data such that most of the data variability is concentrated onto fewer dimensions.

Journal of Experimental Psychology: General, 4 , The American Multiracial Face Database contains faces smiling and neutral expression poses with mixed-race heritage and accompanying ratings of those faces by naive observers that are freely available to academic researchers. The faces were rated on attractiveness, emotional expression, racial ambiguity, masculinity, racial group membership s , gender group membership s , warmth, competence, dominance, and trustworthiness.

Phillips, V. Holland, C. Behavior research Methods, 42, In Proc. The set is made up of nearly photographs of over children ages making 7 different facial expressions - happy, angry, sad, fearful, surprise, neutral, and disgust. High-resolution standardized photographs were taken and supported by the following materials: a basic demographic and appearance-related information, b two types of landmark configurations for Webmorph and geometric morphometrics GM , c facial width-to-height ratio fWHR measurement, d information on photography parameters, e perceptual norms provided by raters.
