: Analyzing patterns used to simulate shades of gray or colors.

: Testing how reducing color depth affects visual quality.

: The "128" in the filename typically refers to its resolution, indicating a 128x128 pixel square format. This low resolution makes it an ideal "lightweight" candidate for rapid algorithm testing.

: This image is part of established datasets—such as those from the University of Southern California (USC-SIPI) —used to test algorithms for image compression, restoration, and edge detection.
