Abstract
A process and a system for compressing highly correlated image data is provided. The system comprises means for capturing the image, means for converting to digital form, means for reshaping the data, means for encoding the repetitions, means for storing the compressed data and means for retrieving the data. The method comprises steps like capturing the image, converting into digital form, reshaping the data into matrix form, encoding the repetitions into a bit-plane index and encoding data values for storage, storing the compressed data in memory and retrieving the data for decompression. The system and method for compressing image and other highly correlated data is described in the description and illustrated by the way of drawings.
Claims24
A method for increasing compressibility of image data of an image wherein each element is compared with a previous element and:
- (a) if they are both equal, a first value is recorded;
- and
- (b) if they are not both equal, a second value is recorded.
A system for compression of an image, the system comprising:
- (a) a camera for capturing at least one image and for supplying digital data;
- (b) a reshaping block for reshaping the digital data into a matrix of image data values;
- (c) a processor for encoding repetitions in the matrix of image data values into a bit-plane index, and for encoding the image data values of the matrix, the encoded repetitions and image data values forming compressed data;
- and
- (d) a memory for storage of the compressed data;
- wherein each image data value is compared with a previous image data value and:
- (i) if they are both equal, a first value is recorded;
- and
- (ii) if they are not both equal, a second value is recorded.
A method for compression of an image, the method comprising:
- (a) capturing the image;
- (b) converting the image into digital form to provide digital data;
- (c) reshaping the digital data into a digital data matrix of image data values;
- (d) encoding repetitions in the digital data matrix into a bit-plane index, and encoding image data values of the digital data matrix to form compressed data;
- and
- (e) storing the compressed data;
- wherein each image data value is compared with a previous image data value and:
- (i) if they are both equal, a first value is recorded;
- and
- (ii) if they are not both equal, a second value is recorded.
A computer readable memory medium stored with a program for increasing compressibility of image data of an image wherein each element is compared with a previous element and:
- (a) if they are both equal, a first value is recorded;
- and
- (b) if they are not both equal, a second value is recorded.
A computer readable memory medium stored with a program for compression of an image, said computer readable memory medium is further stored with a program for:
- (a) capturing the image;
- (b) converting the image into digital form to provide digital data;
- (c) reshaping the digital data into a digital data matrix;
- (d) encoding repetitions in the digital data matrix into a bit-plane index, and encoding image data values of the digital data matrix to form compressed data;
- and
- (e) storing the compressed data;
- wherein each image data value is compared with a previous image data value and:
- (i) if they are both equal, a first value is recorded;
- and
- (ii) if they are not both equal, a second value is recorded.
