Abstract
An encoding system may generate an edge map based on a pixel value difference between neighboring pixels in an inputted image, generate a graph by connecting pixels using the generated edge map, select a prediction value for at least one pixel based on the generated graph, and encode an image based on the selected prediction value.
Claims8
A decoding system, comprising:
- an edge map decoding unit to decode an edge map in an inputted bit string;
- a graph generation unit to generate a graph by connecting pixels through the decoded edge map;
- a prediction value selection unit to select a prediction value for at least one pixel based on the generated graph;
- and
- a prediction compensation unit to restore the at least one pixel based on the prediction value and pixel information of the inputted bit string.
