چکیده

In this paper a real-time surface inspection method based on texture features is introduced. The proposed approach is based on the Local Binary Pattern (LBP) texture operator and the Self-Organizing Map (SOM). A very fast software implementation of the LBP operator is presented. The SOM is used as a powerful classifier and visualizer. The efficiency of the method is empirically evaluated in two different problems including textures from the Outex database and from a paper inspection problem.

GPU architecture for unsupervised surface inspection using multi- scale texture analysis

Surface inspection in manufacturing scenarios is strongly related to accuracy and runtime requirements. To ensure high accuracy and reliable defect detection results, in many applications the environment will be modified with respect to constant illumination and well defined system behavior. In these cases early vision algorithms like edge detection or thresholds are applied for surface inspect...

Genetic Learning Based Texture Surface Inspection

This paper presents a novel approach of visual inspection for texture surface defects. It is based on the measure of texture energy acquired by a kind if high performance 2D detection mask, which is learned by genetic algorithms. Experimental results of texture defect inspection on textile images are presented to illustrate the merit and feasibility of the proposed method.

Comparative evaluation of texture analysis algorithms for defect inspection of textile products

Quality inspection of textile products is an important problem for fabric manufacturers. Currently, the quality control of a fabric of width 1.6-2.0m. which moves at a speed of 8-20 m/min is mostly done by human operators. Texture analysis plays an important role in automatic visual inspection of surfaces. There has been a limited number of applications of texture processing techniques to autom...

Automatic surface inspection using wavelet reconstruction

In automatic surface inspection, one has to solve the problem of detecting small surface defects which locally break the homogeneity of a texture pattern. Textures are generally classified into two major types, structural and statistical [1]. Structural textures are those that are composed of repetitions of some basic texture primitive, such as directional lines, with a deterministic rule of di...
