A Survey on Early Determination of Zero Quantized Coefficients in Video Coding
Journal Title: International Journal on Computer Science and Engineering - Year 2010, Vol 2, Issue 7
Abstract
In video encoding, there are a large number of discrete cosine transform (DCT) coefficients of the prediction residue which are quantized to zeros. Therefore, it is desired to design a method which can early detect zero quantized DCT coefficients before implementing DCT and quantization and thus reduce redundant computations for video coding. This paper presents an overview of some early determination of zero quantized coefficients techniques for video coding. These techniques exploit different ways in order to determine the zero quantized block before DCT and quantization.
