Dual-channel fabric fault detection method based on two-dimensional empirical mode decomposition

The present invention relates to a dual-channel fabric fault detection method based on two-dimensional empirical mode decomposition. Aiming at each step method and parameters in the fabric image feature two-dimensional empirical mode decomposition, an optimal decomposition method is employed to obtain IMFI consisting of fabric texture information and IMF2+3 consisting of rough scale gray information; the texture energy is extracted by using optimal Laws texture measurement, the binaryzation operation is performed, and a texture detection channel result is obtained; the binaryzation operation of the IMF2+3 is carried out, and a gray detection channel result is obtained; and the texture detection channel result and the gray detection channel result are fused, and the fabric fault detection result is obtained, wherein the pixel with the value of 255 in the result represents a faultless region, and the pixel with the value of 0 in the result represents a fault region. The dual-channel fabric fault detection method based on the two-dimensional empirical mode decomposition solve the problem that the two-dimensional empirical mode decomposition is short of the scheme of fabric image decomposition, and on the basis, provides a dual-channel fabric fault detection method according with a human eye work mode.
