MPEG-4 Part 2, MPEG-4 Visual (formally ISO/IEC 14496-2 [1]) is a video encoding specification designed by the Moving Picture Experts Group (MPEG). It belongs to the MPEG-4 ISO/IEC family of encoders. It uses block-wise motion compensation and a discrete cosine transform (DCT), similar to previous encoders such as MPEG-1 Part 2 and H.262/MPEG-2 ...
A discrete cosine transform (DCT) expresses a finite sequence of data points in terms of a sum of cosine functions oscillating at different frequencies.The DCT, first proposed by Nasir Ahmed in 1972, is a widely used transformation technique in signal processing and data compression.
M-JPEG is an intraframe-only compression scheme (compared with the more computationally intensive technique of interframe prediction).Whereas modern interframe video formats, such as MPEG1, MPEG2 and H.264/MPEG-4 AVC, achieve real-world compression ratios of 1:50 or better, M-JPEG's lack of interframe prediction limits its efficiency to 1:20 or lower, depending on the tolerance to spatial ...
