Aiming at the problems existing in the image texture detection,it is put forward a new method of Parallel Gray Level Grade Co-Occurrence Matrix.At first it is needed to determine the image grayscale distribution and to obtain the difference of information as separate categories;then through gray level-gradient co-occurrence matrix,it is calculated the change rate of the image grayscale.At last the channel process is decided and the pixel interconnected mapping test is made.Multichannel parallel process is the multiplication of single channel probability data of interconnection events.Experimental result shows this texture detection method is effective.
