Feb 6, 2023 · Chain code is a lossless compression technique used for representing an object in images. The co-ordinates of any continuous boundary of an object can be represented as a string of …

The boundary chain code (BCC) is defined as a compact technique for encoding image segmentation by representing only the boundary points of an object, utilizing a starting coordinate and directional …

Shape number of a boundary is defined as the first difference of a chain code of the smallest magnitude. The order n of a shape number is the number of digits in its representation. The following figures …

A chain code is a lossless compression based image segmentation method for binary images based upon tracing image contours. The basic principle of chain coding, like other contour codings, is to …

The directional code representing any particular section of line is relative to (and thus dependent upon) the directional code of the preceding line segment. What this means is that relative chain codes have …

The first difference of a chain-coded boundary depends on the starting point. The shape number of such a boundary, based on the 4-directional code is defined as the first difference of smallest magnitude.

11.1 Representation – Chain code codes are used to represent a boundary as a connected sequence of straight line segments of specified length and direction.

The chain code descriptor of various hand shapes was calculated and tested with different classifier such as k-nearest- neighbour (k-NN), Support vector machine (SVM) and Naive Bayes. Principal …

The 4 directional chain code of the object is 0321 and 8 directional chain code of the object is 0642 . Starting point of an object defines the chain code.

Chain_code Chain code feature generation for image processing: Chain codes are used for finding directionality in shape boundaries. They are one of the most useful shape descriptors. By studying …
