In this paper, a new descriptor for the feature extraction of images in the image database is presented. The new descriptor called the Contourlet Co-Occurrence is based on the combination of the contourlet transform and the Grey Level Co-occurrence Matrix (GLCM). In order to evaluate the proposed descriptor, we perform the comparative analysis of existing methods such as Contourlet, GLCM descriptors with the Contourlet Co-Occurrence descriptor for image retrieval. Experimental results demonstrate that the proposed method shows a slightly improvement in the retrieval effectiveness.
