METHOD AND SYSTEM FOR MEASURING VIDEO IMAGE DEGRADATIONS INTRODUCED BY AN ENCODING SYSTEM WITH THROUGHPUT REDUCTION

摘要

The process involves dividing coding of a coded image into blocks. A grid of coding is shifted with respect to the image to define a decomposition of the image in blocks of analysis covering each boundary between two adjacent blocks. A transformation calculation is applied to the data of pixels of the image coding using grid and pixels that are extracted from transformed coefficients for each block of analysis. An Independent claim is also included for a system for measuring degradations in a digital image.
