Feature description based on center-symmetric local mapped patterns

Abstract: Local feature description has gained a lot of interest in many applications, such as texture recognition, image retrieval and face recognition. This paper presents a novel method for local feature description based on gray-level difference mapping, called Center-Symmetric Local Mapped Pattern (CS-LMP). The proposed descriptor is invariant to image scale, rotation, illumination and partial viewpoint changes. Furthermore, this descriptor more effectively captures the nuances of the image pixels. The training set… Show more

“…Other than our proposed textural model, we evaluated the robustness and efficiency of our HPIL model in comparison with other existing texture descriptors using our VELscope ® database, such as gradient directional pattern (GDP) [ 60 ], gradient directional pattern 2 (GDP2), geometric local textural patterns (GLTP) [ 61 ], improved Weber local descriptor (IWLD) [ 62 ], localized angular phase (LAP) [ 63 ], local binary pattern (LBP) [ 64 ], local directional pattern (LDIP) [ 65 ], local directional pattern variance (LDiPv), inverse difference moment standardized (IDN) [ 66 ], local directional number pattern (LDNP) [ 67 ], local gradient increasing pattern (LGIP) [ 68 ], local gradient patterns (LGP) [ 69 ], local phase quantization (LPQ) [ 70 ], local ternary pattern (LTeP) [ 71 ], local tetra pattern (LTrP) [ 72 ], monogenic binary coding (MBC) [ 73 ], local frequency descriptor (LFD) [ 74 ], and local mapped pattern (LMP) [ 75 ]; however, the overall results with these textural descriptors were quite modest (as shown in Table 5 ) as compared to those obtained with our HPIL model, which makes it not suitable for classifying OPMD and standard regions.…”
