Dataset of 213 Grayscale Images Featuring 7 Positive Facial Expressions from 10 Individuals

This database comprises 213 grayscale images representing 7 distinct positive facial expressions from 10 subjects. All images are stored as 256×256 pixel 8-bit grayscale TIFF files, with an average of 2-4 samples per expression per individual. The dataset structure facilitates implementation of facial expression recognition algorithms through standardized image preprocessing and classification techniques.
