R., Heemskerk, A., Harber, A., Wilson, R., Turner, G. The scrambled images are accessible for registered FACES users. All scrambled images are 800x1000 jpeg files (96 dpi). The matrices were then randomly shuffled by these smaller blocks, providing final images that matched the dimensions of the original image and were composed of the same individual pixels, although arranged differently. With the randblock function, original FACES files were treated as 800x1000x3 matrices – the third dimension denoting specific RGB values – and partitioned into non-overlapping 2x2x3 blocks.

Static images used for morphing came from the original FACES database. It is a database of morphed videos (n = 1,026) of young, middle-aged, and older adults displaying six naturalistic emotional facial expressions including neutrality, sadness, disgust, fear, anger, and happiness.

For details see Pehlivanoglu, D., Lin, T., Lighthall, N. Moreover, to provide picture-specific normative data on perceived trustworthiness, 199 adults (aged 22-78 years) rated the trustworthiness of each face in the FACES database.
An adult developmental approach to perceived facial attractiveness and distinctiveness. C., Riediger, M., Lin, T., & Lindenberger, U. More detailed descriptions for the latter two dimensions are available in Ebner, N. FACES-A database of facial expressions in young, middle-aged, and older women and men: Development and validation. The first two dimensions (facial expression and perceived age) are described in Ebner, N., Riediger, M., & Lindenberger, U.

The FACES database was developed between 20 by Natalie C. FACES is a set of images of naturalistic faces of 171 young (n = 58), middle-aged (n = 56), and older (n = 57) women and men displaying each of six facial expressions: neutrality, sadness, disgust, fear, anger, and happiness.
