Comparison of lossy to lossless compression techniques for digital cinema

Improved H.264/AVC lossless intra compression using multiple partition prediction for 4×4 intra block

“…Although it is developed mainly for the lossy compression, it also supports lossless compression and has found some applications such as medical image and digital cinema compression [1,2]. Generally, the H.264/AVC lossless compression is supported by skipping transform because the integer transform of the H.264/AVC is inefficient for the lossless compression.…”

Near-lossless compression for high frame rate videos

“…Also, a lot of research works have been put into developing new methods for compression. There are algorithms based on spatial prediction, such as JPEG-LS, based on transform domain, such as JPEG-2000, MPEG and based on spatiotemporal predictions, like LOPT-3D and GLICBAWLS-3D [5]. Relatively, not too many works has been done on lossless video compression and lossy methods have mainly gotten the researchers attention [7].…”

“…Video compression can be used for entertainment and every day purposes, discussed in [5], as well as special cases, such as [6]. Also, a lot of research works have been put into developing new methods for compression.…”

Effective Video Encoding in Lossless and Near-lossless Modes

“…The near-lossless method may be used for medical images compression, where experts should determine the error tolerance d that does not influence the diagnosis of the medical images of the given type (that compression kind is sometimes referred to as visually lossless (Andriani et al, 2004)), and in the situation when there is recording of video sequences with very large number of frames and only a slight error level can be acceptable. Often used quality measure, PSNR, is treated as not utterly capable of considering human visual perception.…”

“…This is caused by one of the primary applications of the lossless video compression, i.e., edition of television programs, movies etc. (Andriani et al, 2004). In this situation it is not recommended to use lossy compression methods, such as MPEG2, MPEG4 etc.…”
