Abstract
Representation and classification of color texture generate considerable interest within the field of computer vision. Texture classification is a difficult task that assigns unlabeled images or textures to the correct labeled class. Some key factors such as scaling and viewpoint variations and illumination changes make this task challenging. In this paper, we present a new feature extraction technique for color texture classification and recognition. The presented approach aggregates the features extracted from local binary patterns (LBP) and convolution neural network (CNN) to provide discriminatory information, leading to better texture classification results. Almost all of the CNN model cases classify images based on global features that describe the image as a whole to generalize the entire object. LBP classifies images based on local features that describe the image’s key points (image patches). Our analysis shows that using LBP improves the classification task when compared to using CNN only. We test the proposed approach experimentally over three challenging color image datasets (ALOT, CBT, and Outex). The results demonstrated that our approach improved up to 25% in the classification accuracy over the traditional CNN models. We identify optimal combinations for each dataset and obtain high classification rates. The proposed approach is robust, stable, and discriminatory among the three datasets and has shown enhancement in classification and recognition compared to the state-of-the-art method.

Summary
E presented approach aggregates the features extracted from local binary patterns (LBP) and convolution neural network (CNN) to provide discriminatory information, leading to better texture classification results. 1. Introduction e motivation of the usage of CNN models as features descriptors is the ability of the deep neural network to capture the high-level features that can be a key point for the classification of the texture images. Is success motivates us to propose a new technique for color texture classification based on the convolution neural network and local binary pattern to extract global and local features and combine them to obtain high color texture classification results. 2. Convolution Neural Network e primary concept of using CNN features is its capability to capture the high-level features that are considered the key point to separate the texture image. In (1), Pc P(m, n) is the central pixel at (m, n) location, and Pj P(mj, nj) is a neighboring pixel of the central pixel Pc, where
