    Electronic Trace Fossil Image Retrieval Based on Extended Direction Local Binary Pattern

    Based on the direction local binary pattern (dLBP) and the center-symmetric local binary pattern (CS-LBP), an improved direction local binary pattern (idLBP) was presented. The directionality, coarseness and c...

    Improved Region Local Binary Patterns for Image Retrieval

    Two extended patterns, direction local binary pattern (D-LBP) and variance direction local binary pattern (vD-LBP) were introduced in the paper. More texture features are obtained in the new operators by intro...

    An Extended Center-Symmetric Local Ternary Patterns for Image Retrieval

    A new texture spectrum descriptor was proposed for region description in the paper, which is an extension of center-symmetric local ternary pattern (CS-LTP). Different from CS-LTP, the central piexl of the reg...

    Shape Retrieval Based on the Relativity of Chain Codes

    The direction chain code has been widely used in image retrieval for its simplicity and low storage requirement. One problem is that the traditional methods did not consider the relativity among the chain code...
