The method is based on a geometric interpretation of the DCT, and the calculated limits are as close as 14% to the maximum code-lengths. The proposed strategy can be adapted to other transform coding methods, e.g., MPEG 2 and 4 video compressions, to calculate close upper code length limits for the respective processing blocks.US patent application 11/947936Information TheoryComputational ComplexityComputational Engineering, Finance, and ScienceComputer Vision and Pattern Recognitiontext
