High precision and quantization method applicable to wavelet transform matrix

摘要

A method for reducing the entropy of an original matrix comprising the step of using a wavelet transform from the original matrix to a transform matrix, wherein the quantization coefficients correspond to each detail matrix, and the wavelet transform is less than one decimal point Using a first number of digits, e.g., 3 digits after the decimal point. Such a method is particularly suitable for image compression. [Selection figure] None
