Abstract
For at least one component of a digitized image, if a magnitude of a difference between a pixel component value and a representative image-cell-value is less than a threshold for each pixel of a subset of pixels of an image cell of a digitized image, the corresponding pixel component values of corresponding pixels of a corresponding processed image cell are set to the representative image-cell-value. Otherwise, at least the most significant portion of the corresponding pixel component values of the corresponding pixels of the corresponding processed image cell are set to the value of pixel component values of the digitized image.
Claims11
A method of processing a source digitized image, comprising:
- a. selecting a subset of source image pixels of a source image cell of the source digitized image, wherein said subset of source image pixels comprises a plurality of source image pixels;
- b. selecting an image component of said source digitized image to be processed;
- c. processing said plurality of source image pixels of said source image cell so as to generate a corresponding processed image component corresponding to the selected image component for each corresponding processed image pixel of a corresponding plurality of processed image pixels of a corresponding processed image cell, wherein said corresponding plurality of processed image pixels of said corresponding processed image cell are in one-to-one correspondence with said plurality of source image pixels of said source image cell, and the operation of processing said plurality of source image pixels of said source image cell comprises:
- i. if each value of said selected image component for each source image pixel of said source image cell differs from a representative image-cell-value by no more than a first threshold value for every said source image pixel of said plurality of source image pixels of said source image cell, then a corresponding set of processed values for said selected image component for each of said plurality of source image pixels of said corresponding processed image cell is generated responsive to a first set of processing operations, wherein said representative image-cell-value is representative of said selected image component for set subset of source image pixels of said source image cell,
- ii. otherwise if at least one said value of said selected image component of said subset of source image pixels of said source image cell differs from said representative image-cell-value, by more than said first threshold value, then said corresponding set of processed values for said selected image component for each of said corresponding plurality of processed image pixels of said corresponding processed image cell is generated responsive to a second set of processing operations,
- iii. wherein said first set of processing operations comprises setting said value of said selected image component of each said corresponding processed image pixel of said corresponding processed image cell to said representative image-cell-value of said selected image component for said source image cell;
- and
- iv. said second set of processing operations comprises, for each said source image pixel of said source image cell setting at least a most-significant portion of said selected image component of said corresponding processed image pixel to the value of said selected image component of a corresponding said source image pixel.
