Which algorithm is used for image compression?

Image files can take up a lot of space, so computers employ a range of algorithms to compress image files. For the simplest of images, computers can use a compression algorithm called run-length encoding (RLE).

Which compression method is preferable in the image and video compression context?

DCT is the most widely used lossy compression method, and is used in multimedia formats for images (such as JPEG and HEIF), video (such as MPEG, AVC and HEVC) and audio (such as MP3, AAC and Vorbis).

What are the image compression standards?

JPEG is an image compression standard that was developed by the “Joint Photographic Experts Group”. JPEG was for- mally accepted as an international standard in 1992. JPEG is a lossy image compression method. It employs a transform coding method using the DCT (Discrete Cosine Transform).
