- Description
- MAT (MATLAB Image Format) is an image file format created by MathWorks for storing and sharing MATLAB data and images. It contains data in a binary format, as well as metadata describing the image. MAT files can be used to store images, 3D models, and other types of data.
- A PGM file is a grayscale image file saved in the portable gray map (PGM) format and encoded with one or two bytes (8 or 16 bits) per pixel. It contains header information and a grid of numbers that represent different shades of gray from black (0) to white (up to 65,536). PGM files are typically stored in ASCII text format, but also have a binary representation.
