Abstract
A method and apparatus for compressing digital image data to improve the efficiency of serial data transmission is disclosed. More specifically, the present invention accomplishes image transmission by providing multiple image processing modules, and then selecting the module that will process the entire in the most efficient manner, based upon the content of the data contained in the image. Image content is analyzed using hierarchical vector quantization.
Claims20
A method of improving the speed and efficiency of electronic data transmission, comprising the steps of:
- a) acquiring input image data which represents the light intensity of an image;
- b) segmenting said input image data to form a plurality of image data blocks;
- c) selecting, based on an image content, a module for receipt of an input image data block;
- and
- d) processing said received image data block in said module.
An apparatus for improving the speed and efficiency of electronic data transmission, comprising:
- a) a segmenter which divides image data into a plurality of input image data blocks, wherein said image data corresponds to the light intensity of an original image;
- b) a plurality of image processing modules communicating with said segmenter, wherein any of said modules may process said segmented image data blocks;
- and
- c) an image analyzer communicating with said input image data blocks and with said modules to designate one of said modules for processing of a segmented image data block, based upon a content of said segmented image data block.
