Surface Defect Detection of Rubber Oil Seals Based on Texture Analysis

Conference paper
Part of the Lecture Notes in Electrical Engineering book series (LNEE, volume 222)


The inspection of surface texture is an important part of many industrial quality control applications. The detection of features and classification based on it in a digital image is the key requirement in quality control systems in production and process. An inspection system to replace human inspectors should be capable of detecting flaws such as scratches, stains, (textural defects) and dents, cracks, blow holes (structural defects) occurring in various shapes and sizes. This paper aims at surface defect detection on rubber oil seals based on texture analysis. The proposed method is based on statistical method by extraction of textural features computed from Gray level co-occurrence matrix with different spatial relationships. As the defects were locally concentrated, computing the textural features of the entire image did not prove to be effective, hence the images were divided and then the features were obtained. Also a unique preprocessing method has been proposed and implemented.
