Because there are a lot of original information at the edge during image processing, thus, we can get the real image data in terms of the data acquisition. The usage of edge is often in the case of some irregular geometric objects, and we determine the contour of the image by combining with signal transmitted data. At the present stage, there are different algorithms in image edge detection, however, different types of algorithms have divergent disadvantages so It is diffi cult to detect the image changes in a reasonable range. We try to use wavelet transformation in image edge detection, making full use of the wave with the high resolution characteristics, and combining multiple images, in order to improve the accuracy of image edge detection.展开更多

In the process of scientific and technological progress, ensuring that technology can serve the public better is a problem that needs to be faced in our study. In our daily life, computer networks have become essential to everyone, and the use of computers can bring a lot of convenience to the public which is also an important guarantee for the continuous development of society. However, when we use computers, we will face the problems related to computer network security. These problems will bring a lot of negative results for users or industries. Based on these considerations, in the process of using a computer network, we have to maintain the network system. In this paper, we discussed the development situation and problems of computer network security at the present stage. And in the process, we are looking for more solutions to maintain the security of computer network.展开更多
