| Abstract: | Rate of broken rice is an important factor in the measuring of appearance quality of rice.An automatic detection method of broken rice rate is obtained based on morphology principle,digital image processing and analyzing.Based on national standards,a detection method is developed which eliminates the noise of image and the bad illumination condition by morphology open operation,uses an improved Otsu algorithm to segment the image,and calculates rice number and area by region labeling algorithm.The experimen... |
