摘要：In automatic fabric inspection, fabric image acquires impulse noise due to malfunctioning in camera sensors, faulty memory locations in hardware, or transmission via a noisy channel. Eliminating such noise is an important preprocessing task. The fabric image should be enhanced to achieve a high interpretability of perception to detect defects. In this paper contrast stretching, grey level thresholding and median filters are used to enhance the fabric image. The performances of these methods are evaluated using Peak Signal to Noise Ratio (PSNR) and Mean Square Error (MSE). The contrast stretching with spatial median filter gives suitable results to enhance the perception of defects
