Image Processing: it is any form of signal processing for which the input is an image, such as a photograph or video frame; the output of image processing may be either an image or, a set of characteristics or parameters related to the image.
Image Compression: The objective of image compression is to reduce irrelevance and redundancy of the image data in order to be able to store or transmit data in an efficient form. Broadly Image Compression is of two types. Lossless and lossy compression are terms that describe whether or not, in the compression of a file, all original data can be recovered when the file is uncompressed.
Image Restoration: t is the area that deals with improving the appearance of an image. The main purpose of restoration is to remove the noise. Image restoration is the operation of taking a corrupted/noisy image and estimating the clean original image.
