Abstract: In the literature local based methods are popular in extracting facial features. The local binary pattern (LBP) and its variants are one of the popular approaches to extract local features more significantly and precisely and they have been using in many image processing applications. The texons based methods also extract local structural information on a micro grid of 2 x 2 and they are very popular in CBIR. This paper has overcome the disadvantages of the existing texton methods by proposing gradient integrated texton matrix (GITM).This paper initially derives a gradient on facial image and then derives textons on the gradient image. The proposed gradient integrated texton matrix (GITM) defined textons by combining the textons derived in TCM and MTH and GITM has overcome the ambiguity issues of MTH in identification of textons and representation issues of minute textons and complex fusing operations of TCM. The proposed GITM represents the blob, triangle and line shapes of 2 x 2 grids and is specially intended for facial image analysis and can achieve higher face recognition rate than other local based methods. The GLCM features derived on GITM integrates the structural, edge, texture and statistical features of facial images more accurately and precisely. The proposed GITM is specially intended for facial image analysis and can express the spatial correlation of textons and can be considered as a generalized visual attribute descriptor. The proposed GITM descriptor is experimented on popular databases and the results are compared with state of art local representative based methods, the experimental results demonstrate the efficacy of the proposed method over the existing ones.
