Problems solved by technology

[0004] However, the existing chain code coding method can only be used to realize the coding of a single region boundary in an image. Because it does not define the data structure of the chain code, the existing chain code coding method cannot realize the multi-region boundary coding in a complex image. Coding, limited range of applications

Embodiment Construction

[0014] The image to be coded can be composed of multiple regions according to different colors, and each region can contain multiple subregions according to different colors, and each subregion can further include multiple subregions according to different colors. Or sub-regions can be represented by chain code after chain code encoding. Such as figure 2 As shown, assuming that the image to be encoded includes m regions, the chain code of the encoded image may include region chain code 1, region chain code 2 to region chain code m; region chain code 1 may include sub-region chain code 11, sub-region chain code Area chain code 12 to sub-area chain code 1p, area chain code 2 can include sub-area chain code 21, sub-area chain code 22 to sub-area chain code 2q, area chain code m can include sub-area chain code m1, sub-area chain code Area chain code m2 to sub-area chain code mr; each sub-area chain code can further include multiple sub-areas.

Abstract

The invention discloses a storing method of an image chain code. The method comprises the steps of step 1, inputting an image to be coded; step 2, encoding a chain code for different regions and sub-regions under different regions in the image to be coded; and step 3, implementing associative storage for the generated chain codes of different regions and different sub-regions to form a data storage structure of the image chain code, enabling the coding of overall chain code of a complicated image, and expanding the application field of the coding of the chain code. When an animation image is processed, the generation of the animation image can be sourced from the extraction of a real scenic image, so that the generation of the animation is unnecessary to limit to the artificial drawing.

Description

technical field [0001] The invention relates to a method for storing image chain codes. Background technique [0002] Chain code coding is a very commonly used coding technology for representing lines, plane curves and region boundaries in image processing and pattern recognition. It can store more information with less data and is widely used in image region boundaries. coding field. [0003] At present, the most important chain code encoding method is the Freeman chain code proposed by Freeman in 1961. A form of the chain code moves along the digital curve or border pixels in an 8-adjacent manner, and each moving direction is coded by a digital set {i|i=0, 1, 2, ... 7}, which means that it is the same as X The angle of 45o×i in the positive direction of the axis, such as figure 1 shown. A chain code can be viewed as a series of small straight line segments with fixed direction and length. In addition, commonly used chain code encoding methods include vertex chain code...
