The Edge Detection of Rice Image Based on Mathematical Morphology and Wavelet Packet

摘要：

In accordance with the characteristics of the paddy images, this article designs a rice image acquisition device which consisted of one low-cost CCD sensor camera, two LED lamps, a detection box, a test-bed, and a PC computer. The device was designed to work to facilitate the study of image processing algorithms. Firstly, the algorithm of wavelet packet and mathematical morphology in the method is taken to smooth the interferences of surface scratches and glistens effectively. Secondly, the processed image is detected the image edge with Canny operator. In this paper, we used three algorithms of edge detection including: morphological edge detection, wavelet packet edge detection, edge detection combining morphological and wavelet packet. Experiments show that the edge detection combining morphological and wavelet packet can denoise and protect images has good practicality for its relatively high measurement precision, which are of great value towards the engineering practice.
