It uses a series method such as filtering to get a preprocess result, and does spot projection to get circum-rectangle of the accumulation object in order to get rid of the noise’s interference. It uses improved gray co-occurrence matrixes to reserve the contradiction of window’s size and the precision of segmentation. 2D OTSU threshold is used to get a precise segmentation result. Experimental results show that the area segmented by the method is clear and with high veracity.
