The texture set is suitable for evaluating and comparing texture measures, their sensitivity to noise and geometric transforms. It is comprised of 28 classes with 160 unique samples per class. The samples are 576x576 pixels large and stored as gray scale 8-bit png-images. The original images were acquired in a lossless raw format followed by correction for chromatic aberration, lens distortion and vingetting. After conversion to gray scale the intensity was normalized for all samples to the same mean and standard deviation. In addition, 12 rotations of each sample are also available.
