The Shape of Fruit Recognition Using Matching Round

Information extraction is an important part of the image processing. As the economic and technological development, the image quickly extracts information technology has been gained more needs and applications in many society fields. At home and abroad, there are many scholars to study how to quickly extract useful information from the image. Gray, binarization, the largest connected block extraction, contour extraction, corrosion, expansion and circle fitting technique have been used in this paper to match a known circle from a large number of irregular rounds.
