Abstract

This thesis is describing methods of lossless video compression. It also contains the description and formulas for conversions of color models suitable for lossless compression. The last theoretical part describes context compression and entropy coding with emphasis on arithmetic coding. Following the arithmetic coder is the description and details about the implemented video codec. This codec is then tested and compared with the currently used FFV1 and Huffyuv codecs. The result of this thesis is that adding the number of contexts improves the compression ratio although it does not outperform the compression ratio of FFV1, the compression ratio of Huffuyv was always outperformed.

Keywords

compression, video, lossless compression, color models, predictors, entropy coding, arithmetic coding, context compression
