Abstract: In order to identify the chest bitmap bullet holes quickly and accurately through image processing, a new method, which combines bullet hole edge features with the HIS color space characteristics, is presented to realize the chest bitmap bullet holes identification. The chest bitmap bullet holes edge is determined and strengthened with the morphological edge detection algorithm, to improve the contrast between the holes edge image and the background. And then the color feature data is extracted to identify the bullet holes in the chest bitmap. Experiments and calculation results show that this method can be used to extract the bullet holes from just an imaging chest bitmap accurately, and to reduce the influence of image recognition effects from natural environment light, dust, distortion and the target image noise caused by vibration.
