Compression Within A Set Of Images

Abstract

The present disclosure relates generally to a system and method for file compression. More specifically, the disclosure introduces to a method for file compression wherein a group of files is identified by comparing a plurality of similarity characteristics. The group of files may then be compressed relative to at least one base file to improve compression efficiency.

What is claimed is: 
     
         1 . A method for compression of a group of images comprising:
 identifying at least one base image among a group of images, the at least one base image corresponding to at least one common feature of the group of images;   defining each image of the group of images as a compressed image relative to the at least one base image based on the at least one common feature of the image of the group of images;   generating image compression data comprising a relationship of each image of the group of images to the at least one base image; and   storing each compressed image of the group of images and the image compression data.   
     
     
         2 . The method according to  claim 1 , wherein defining each image of the group of images as a compressed image comprises comparing each image of the group of images to the at least one base image through a recurring comparison to identify a plurality of recurring features. 
     
     
         3 . The method according to  claim 2 , wherein defining each image of the group of images as a compressed image comprises removing at least one recurring feature of the plurality of recurring features from at least one image of the group of images. 
     
     
         4 . The method according to  claim 3 , wherein the at least one recurring feature is removed via a motion compensation algorithm. 
     
     
         5 . The method according to  claim 3 , further comprising storing a relationship of the at least one recurring feature to the at least one image of the group of images and the at least one base image in the image compression data. 
     
     
         6 . The method according to  claim 1 , wherein compression data is stored in a header file relating each image of the group of images to the at least one base image. 
     
     
         7 . A system for compression among a set of images comprising:
 a memory unit;   a processor operably coupled to the memory unit, the processor comprising at least one module configured to:
 search a plurality of images and identify a group of images corresponding to at least one similarity characteristic; 
 identify a base image of the group of images corresponding to at least one common feature of the group of images; 
 compare each image of the group of images to the at least one base image; and 
 define each image of the group of images as a compressed image relative to the at least one base image based on the at least one common feature, wherein at least one recurring feature between each image of the group of images and the at least on base image is compressed. 
   
     
     
         8 . The system according to  claim 7 , wherein the at least one module is further configured to generate compression data, the compression data defining a relationship of the at least one recurring feature of each image of the group of images to the at least one base image. 
     
     
         9 . The system according to  claim 7 , wherein the processor is configured to initiate the at least one module in response to activation of a scheduled compression task. 
     
     
         10 . The system according to  claim 7 , wherein the processor is configured to initiate the at least one module in response to an available processing capacity. 
     
     
         11 . The system according to  claim 7 , wherein the memory unit comprises a memory in a mobile device. 
     
     
         12 . A method for file compression comprising:
 searching a plurality of files and identifying a group of files corresponding to at least one similarity characteristic of the plurality of files;   identifying a base file of the group of files corresponding to at least one common portion of the group of files;   comparing the group of files to the at least one base file; and   defining each file of the group of files as a compressed file relative to the at least one base file based on the at least one common portion of each file, wherein at least one common portion of each file of the group of files is compressed relative to the at least on base file.   
     
     
         13 . The method according to  claim 12 , further comprising comparing each file of the group of files through a recurring comparison to the at least one base file to identify and compress at least one common portion among a group of compressed files. 
     
     
         14 . The method according to  claim 12 , wherein the group of files comprises a group of audio files. 
     
     
         15 . The method according to  claim 12 , wherein the group of files comprises a group of digital media files. 
     
     
         16 . The method according to  claim 12 , wherein compression data is stored in a file compression table defining the relation of each file of the group of files to the at least one base file. 
     
     
         17 . The method according to  claim 12 , wherein the at least one similarity characteristic comprises a timing of image capture of each file of the group of files. 
     
     
         18 . The method according to  claim 12 , wherein the at least one similarity characteristic comprises a location of image capture of each file of the group of files. 
     
     
         19 . The method according to  claim 12 , wherein the at least one similarity characteristic comprises a resolution of each file of the group of files. 
     
     
         20 . The method according to  claim 12 , wherein the at least one similarity characteristic comprises a file name of each file of the group of files.
