Abstract
A system and method for discriminating among image characteristics in order to select among a plurality of compression techniques. Multiple compression schemes are applied to a source image (101) concurrently and the results are stored. Image discrimination is performed in parallel with the image compression to generate a recommendation regarding the stored compressed images.
Claims27
A system for discriminating among image characteristics in order to select among at least two compression techniques, the system comprising:
- a first compressor for compressing a source image using a first compression method to obtain a first compressed image;
- coupled to the first compressor, a first storage device for storing the first compressed image;
- a second compressor for compressing the source image using a second compression method to obtain a second compressed image;
- coupled to the second compressor, a second storage device for storing the second compressed image;
- an image discriminator for characterizing the source image according to predefined criteria, and to generate and output a recommendation between the first and second compression methods;
- and
- coupled to the image discriminator, the first storage device, and the second storage device an input device for accepting a user input signal to select between the first and second compression methods.
A method of discriminating among image characteristics in order to select among at least two compression techniques, comprising:
- a) compressing a source image using a first compression method to obtain a first compressed image;
- b) storing the first compressed image;
- c) compressing the source image using a second compression method to obtain a second compressed image;
- d) storing the second compressed image;
- e) characterizing the source image according to predefined criteria, and generating and outputting a recommendation between the first and second compression methods;
- and
- f) accepting a user input to select between the first and second compression methods.
