Efficiency of chain codes to represent binary objects
WebThe primitives chain code (PCC) is described as an extension of the Freeman chain code, with each PCC codeword representing either a portion of a zero- to three-pixel chain or an endline, junction, or break feature. A simple context-free syntax is described which … WebFeb 17, 2024 · The algorithm of reflection symmetry detection based on the pair-wise alignment of skeleton primitive chains: 1. Build the skeleton of the shape and to code the skeleton by the chain of primitives . All skeleton vertices are considered as ordered. 2. Choose a vertex of the skeleton as start point. 3. WebThe conventional four-connected and eight-connected chain code by Freeman [1], primitive chain code by O’Gorman [3], and triangular, rectangular, and hexagonal cell by Bribiesca [2] are among the chain code proposed to represent 2D shape. eib football team
