Real time processing and transmission using these devices requires image compression algorithms that can compress efficiently with reduced complexity. Due to limited resources, it is not always possible to implement the best algorithms inside these devices. In uncompressed form, both raw and image data...
Lossy image compression retains the most significant information for the image without keeping every single pixel. There are several types of lossy compression algorithms, described in more detail below. But all work by removing information from the image file so that the file is comprised of fewer...
