Study on recogniton of jujube insect by computer vision

摘要

Ancylis sativa Liu is a kind of insects to cause severe damage to jujube trees. This paper studies the recognition of Ancylis sativa Liu from catchers via using computer vision technique. The image of a Ancylis sativa catcher generally shows not only Ancylis sativa but also other objects. Consequently it leads to that the image has a complicated background and an uncertain interesting region. Ancylis sativa Liu are able successfully to be recognized from the image as follows. Firstly, the region of interest is extracted from the image by enhancing the contrast of Ancylis sativa Liu to the background. Secondly, the outline of Ancylis sativa Liu shape is drawn by identifying the vertexes of the object figure. The recognition of Ancylis sativa Liu is effective and practical. It can be expected to be applied to the detections of similar kinds of jujube insects.
