|Description (include details on usage, files and paper references)||The Textures volume currently contains 154 images, all monochrome, 129 512x512 and 25 1024x1024.
For the Brodatz texture images, the number in parenthesis (i.e. D12) is the page number of the corresponding texture in the Brodatz book (P. Brodatz, "Textures: A Photographic Album for Artists and Designers", Dover Publications, New York, 1966). These digital images are not scans of the pages from the texture book. The images are scans of a set of glossy black and white prints that were purchased from the author. While these prints are pictures of the same textures as in the book, in most cases they are not the same image as the one in the book.
Brodatz texure Images 1.2.01 through 1.2.13 are histogram equalized versions of 1.1.01 through 1.1.13 and are marked with "H.E." in the list below.
The 512x512 Brodatz images of pigskin (1.1.11 and 1.2.11) are missing the last 26 lines of the texture data. The image file is 512x512 but the texture data only occupies the upper 486 rows of the image. Rows 487 through 512 in the file are all zeros. This is most likely something that occured years ago during the scanning of the image and there are no plans to fix it. The other 512x512 Brodatz images (1.1.01 through 1.2.13) are missing the texture data in last two lines of the image file. The actual image data in these images are only 512 pixels wide by 510 lines high. The last two lines of all these images contain zeros.
The texture mosaics (texmos1, texmos2, and texmos3) are mosaics of eight Brodatz textures that were used for research in image texture segmentation at USC-SIPI. The files texmos2.s512 and texmos3.s512 are images showing which pixels are from which textures in the corresponding mosaics.
Like the individual texture files, mosaic texmos3.p512 is also missing the texture data in the last two rows of the image. This has been fixed in texmos3b.p512. The shape of the texture regions, and the texture in each region is the same as in texmos3.p512, but the texture data that appears in the four regions that touch the bottom edge of the image has been moved down two lines to fill in the empty lines.
