WebClosed 5 years ago. I have a large binary file that represents the alpha channel for each pixel in an image - 0 for transparent, 1 for anything else. This binary data needs to be dynamically loaded from a text file, and it would be useful to get the maximum possible compression in it. WebBinary Sparse Matrix storage is one of the critical problems in embedded system applications. Storing these matrices in the memory efficiently is important. Magnitude of increase in matrix size also has significant impact on the memory requirement. Sometimes, it might not be possible to accommodate the data due to memory constraints. In this …

WebA binary image can be stored in memory as a bitmap, a packed array of bits. A 640×480 image requires 37.5 KiB of storage. Because of the small size of the image files, fax machine and document management solutions usually use this format. Most binary images also compress well with simple run-length compression schemes.
