What is the difference between .mat and .otb?

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.; The OTB (Nokia Over The Air Bitmap Image) file format is a type of image file developed for use on Nokia mobile devices. These files are specifically optimized for efficient transmission and display on Nokia phones, particularly older models. The OTB format is designed to be compact to facilitate over-the-air (OTA) transmission, which was an essential feature in the era of limited bandwidth and data transfer capabilities. The format supports monochrome graphics, making it suitable for simple images like icons and logos.
