Based on analysis of contours of irregular region, and according to the characteristic that massive continuous code and the same specific code combination are usually contained in a region boundary's vertex chain code, a new effective contour tracking algorithm and representation method based on the pixel vertex matrix is proposed. Moreover, we re-encoding the new vertex chain code using a Huffman...
Forest fire detection includes satellite monitoring, manual monitoring, aerial survey and so on. Compared with these expensive ways, a more practical fireproofing surveillance system needs to be built. An image capture system can be set up in the tower to sent fire image back to the command centre, using the short wave radios equipped for manual monitoring in the towers. Considering the finitude of...
Medical image registration methods based on the maximization of mutual information have shown promising results. But it needs much computing time. This paper presents a new method to rigid registration based on the combination of scale images and mutual information. Firstly, the concept of area morphology is introduced. And then, the scale images are constructed with the area morphological operators...
