ABSTRACT

Defect of onion was depreciated the product value and cause storage disease seriously. In this paper dose a onion surface check using a real time image process at the onion production line. Finally developing a automatic selection system using image processing technique. This system does false retrieval of a onion at a onion production line. At first, a onion image was read in real time using a CCD camera. In this paper, we use an area scan CCD camera. Image is converted into a binary code image using a high-speed imaging process board afterwards. And RGB color image is converted into a HSI color image. Then, onion surface feature is extracted by a HSI color image. Surface false retrieval is finally executed using a onion feature. In this paper, we use an area feature of a onion image.
