Abstract
Abstract A technique involving the standardization of the subject matter of an image and the compression of the image using features of the standardization can provide for a high compression ratio. This technique can be used to improve the quality of a restored image for a predetermined amount of storage space.

A method of increasing the compression ratio for a library of facial images, the method comprising the steps of: automatically standardizing spatial features and characteristics and identifying regions of increased informational significance of the images; and automatically compressing each image and providing an increased data density in each compressed image responsive to the standardizing and identifying; wherein said standardizing step includes the steps of: selecting image features in an order of importance; providing set of images from said library which enhances the selected features; determining image feature constraints for said selected features; automatically processing said image to meet said image feature constraints, wherein said image feature constraints comprising compression and image quality requirements; and positioning eyes and facial orientation in each image in a standard locational configuration; and wherein said providing step includes the step of: providing compressed data in a region of a face having a higher compression ratio than non-facial regions.
Claim 5
Independent Claim
189 words
A method for providing a higher compression ratio for each image in a library of images, said method comprising the steps of: automatically spatially standardizing the images forming said image library to provide spatial correlations between features of the standardized images; automatically compressing said standardized images using the spatial correlations between said standardized images; and automatically decompressing said compressed standardized image to provide a visual image; wherein said standardizing step includes the steps of: identifying image features in an order of importance; processing images to enhance said image features; identifying constraints of said image features; processing said image to meet the constraints; and automatically assigning image regions based on a presence of a desired image quality and a desired image compression;. wherein said processing images step includes the steps of: processing said images using vector quantization; and providing a plurality of codebooks, each codebook comprising representative images corresponding to said vector quantization, wherein each image region has a selected codebook for processing each image region; and wherein said decompressing step further include the step of decompressing each image region using said selected codebook which used in said compressing step.
Claim 6
Independent Claim
189 words
A method for providing a higher compression ratio for each image in a library of images, said method comprising the steps of: automatically spatially standardizing the images forming said image library to provide spatial correlations between features of the standardized images; automatically compressing said standardized images using the spatial correlations between said standardized images; and automatically decompressing said compressed standardized image to provide a visual image; wherein said standardizing step includes the steps of: identifying image features in an order of importance; processing images to enhance said image features; identifying constraints of said image features; processing said image to meet the constraints; and automatically assigning image regions based on a presence of a desired image quality and a desired image compression;. wherein said processing images step includes the steps of: processing said images using vector quantization; and providing a plurality of codebooks, each codebook comprising representative images corresponding to said vector quantization, wherein each image region has a selected codebook for processing each image region; and wherein said decompressing step further include the step of decompressing each image region using said selected codebook which used in said compressing step.
