【Abstract】 In the background that X-ray has been applied in the field of food impurity detection,the traditional image processing algorithm of Canny operator need to set the threshold manually. In view of this shortcoming,a kind of improved adaptive threshold edge detection algorithm is proposed. With the hardware system set up,the X-ray image feature extraction and recognition,combined with the support vector machine method is used to determine whether there is a foreign body,and this achieve the desired goals.更多还原
