Abstract
A method for compressing an image having rows and columns, comprising providing an image, sub-sampling the image into a plurality of sub-image by selecting subsets of non-overlapping pixels in neighboring rows and columns in the image and encoding the sub-images in a video sequence.
Claims48
A method for encoding an image data, comprising:
- (a) receiving an image having a plurality of pixels;
- (b) selecting a plurality of subsets of non-overlapping pixels from the plurality of pixels, yielding a plurality of sub-images of the image;
- and
- (c) encoding the plurality of sub-images as a plurality of frames in a video sequence;
- wherein an area coverage of each of the plurality of sub-images and the image is similar;
- wherein a plurality of neighboring pixels of a certain pixel of the plurality of pixels in one of the plurality of subsets are sampled to at least two other subsets of said plurality of subsets, said plurality of neighboring pixels are sampled from at least one column and at least one row which are neighboring to the certain pixel.

A method for encoding an image having rows and columns, comprising:
- (a) providing an image;
- (b) sub-sampling the image into a plurality of sub-images by selecting a plurality of subsets so that each pixel from a certain pixel of said row and column of pixels in the image is sub sampled to a different subset from its neighboring pixels in at least one neighboring row of pixels and at least one neighboring column of pixels in the image;
- and
- (c) encoding at least a subset of the plurality of sub-images as a plurality of frames of a video sequence;
- (d) presenting the video sequence;
- wherein an area coverage of each of the plurality of sub-images and the image is similar.

A method for compressing a plurality of images having a relative large similar portions therebetween, comprising:
- (a) providing the plurality of images;
- (b) selecting a plurality of subsets of non-overlapping pixels in the plurality of images, yielding a plurality of sub-images of the plurality of images, each of the plurality of subsets is selected from pixels of another of the plurality of images, first pixels of a first the subset are selected from a certain image of the plurality of images and second pixels of a second the subset are selected from a subsequent image of the plurality of images so that the first and second pixels do not overlap in position;
- and
- (c) encoding at least one of the plurality of sub-images as a plurality of frames in a video sequence;
- wherein the plurality of images and the plurality of sub-images having a common area coverage.

An apparatus for compressing and decompressing an image, comprising:
- (a) a splitter configured to sub-sample an image having a plurality of pixels into a plurality of sub-images comprising a plurality of subsets of non-overlapping pixels of the image;
- and
- (b) an encoder configured to encode at least one of the plurality of sub-images in a video sequence as at least one frame of a plurality of frames in a video sequence;
- and
- wherein an area coverage of each of the plurality of sub-images and the image is similar;
- wherein a plurality of neighboring pixels of a certain pixel of the plurality of pixels in one of the plurality of subsets are sampled to at least two other subsets of said plurality of subsets, said plurality of neighboring pixels are sampled from at least one column and at least one row which are neighboring to the certain pixel.
