Dynamic generation of a quantization matrix for compression of a digital object

摘要

Some aspects of the disclosure relate to a compression technique that can permit determining dynamically a satisfactory quantization matrix based at least on properties intrinsic to a digital object being compressed and a predetermined compression quality criterion, wherein the quantization matrix is associated with a specific space-domain-to-frequency-domain transforms. In one aspect, the compression technique can permit creation of a compressed digital object that can satisfy a predetermined a compression quality criterion.

1. A method, comprising:
receiving a correlation metric associated with a digital object quality; receiving a digital object; determining a digital variation metric of the digital object; determining, based on at least the digital variation metric and the correlation metric, a quantization matrix for compression of the digital object; and compressing the digital object according to a compression scheme comprising the quantization matrix, wherein the compressing the digital object according to the compression scheme comprising the quantization matrix allows a user to specify a quality, wherein the quality relates to the digital object after decompression.
