摘要
An apparatus and method to encode the run-lengths and amplitude of the quantized DCT coefficients in a lossless manner is used to achieve compression. Specifically, Golomb-Rice coding is used to encode both zero runs and non-zero amplitudes of the DCT coefficients after quantization. It is found that the use of a scheme taking advantage of an exponential distribution of data, such as Golomb-Rice coding, allows for higher coding efficiencies than alternate schemes.
