- Abstract:
-
In this study, a modified complete local binary pattern (CLBP) feature extraction method based on the local contrast enhancement is proposed to address the influence of illumination on the feature extraction of fabrics and the limitations of the traditional CLBP algorithms. In this method, a local contrast enhancement algorithm is used to preprocess the fabric images that are affected by illumination, and the modified CLBP algorithm is used to calculate the feature value of every lattice in every image after lattice segmentation and to subsequently calculate the relative divergence KLD between the feature of every lattice and the standard feature value. Subsequently, the calculated relative divergence will be compared with the threshold, and the lattice that exhibits a value larger than the threshold is considered to be a defect area. The experimental results obtained using the standard star pattern and the box pattern databases denote that the proposed method is better than the remaining preprocessing methods, and the recall rate of the majority of the detection results obtained using this method can reach approximately 0.99.
