The properties of texture present in an image can be derived in different ways. Local Binary Pattern(LBP) operator is one among them in which a centre pixel is compared with the neighboring pixels to obtain a feature vector. However, the directions are not obtained in this method. The Directional Local Extrema Patterns(DLEP) are used to encode the relationship between the reference pixel and its neighbors by computing the edge information in four directions .In this paper, we propose a new feature vector which is a combination of DLEP and Gabor filter to derive the feature which can be used in the process of Image retrieval.
