Image Compression and Lossless Reconstruction of Digital Image

摘要

The present invention is related to a system and method that provides 100% numerically lossless reconstruction of the image as compared from its uncompressed source. The method of the present invention is configured to compress the raw Red-Green-Blue (RGB) data from a digital image stored on a device and the method further comprises the steps of compressing the pixel (Pc) only if the RGB component of the pixel (Pc) to be compressed is predictable using the RGB component of the neighboring pixels (PN) by using the methods (m01-m16) else the pixel (Pc) is retained.

1. A method that compresses the raw Red-Green-Blue (RGB) data from a digital image comprises the steps of:
a) identifying the pixel (Pc) to be compressed; b) identifying the neighboring pixels (PN) preceding the pixel (Pc) to be compressed; c) checking if the RGB component of the pixel (Pc) to be compressed is predictable using the RGB component of the neighboring pixels (PN); d) compressing the pixel (Pc) if the RGB component of the pixel (Pc) to be compressed is predictable using the RGB component of the neighboring pixels (PN), else
retaining the pixel (Pc) if the RGB component of the pixel (Pc) to be compressed is not predictable using the RGB component of the neighboring pixels (PN).
