Digital image coding distortion modeling procedure, involves applying estimation model of coding distortion weighted by exponential, to information representing energy measure of digital image

摘要

The procedure involves applying estimation model of coding distortion weighted by exponential, to information representing energy measure of digital image. A parameter tuple is searched and the distance between a cloud of points/scatter plots and an entire set of distortion points is minimized, where the scatter plots represents the real distortion measured of a set of image data according to a measure of their energy. Independent claims are also included for the following: (a) a procedure for selecting a transcoding method for a digital image (b) a procedure for regulating the coding rate/speed of a digital image (c) a modeling device for the distortion generated by the coding of a digital image (d) a device for selecting a transcoding method (e) a device for regulating the coding rate/speed of a digital image (f) a computer program that can be loaded in to programmable device to install steps of modeling procedure.
