The first step is to eliminate all kinds of noises generated in the process of collecting traffic video by means of median filter; Then we finish image sharpening with Laplace operator to clarify edges of the video images; finally, image contrast is enhanced with the help of the second-developing packet SDK-2000, which is provided by our video-collecting card. This way, much more satisfactory images are obtained, and preparation is already made for the following work, thats image analyse.Thirdly, according to the characteristics of our system, mobile objects are distinguished by means of image difference. Then some features such as regional area, length and width of traffic objects are selected and extracted. After processing of scale filter, we successfully recognize those moving vehicles appearing in the monitoring regions.Fourthly, some corresponding algorithms are brought forward to automatically identify those familiar traffic peccancies of many sorts, such as red light violation, yellow-line covering, parking in prohibited spots, over-speed running and converse running. Then we find means to snap pictures and to intercept videos of the spot, and collect a lot of relevant information such as the time, the block, the running direction and the weather conditions and so on. According to this information, our traffic management departments could make correct decisions on punishing those drivers who have broken the traffic rules.Considering the complexity of traffic environments on particular blocks, in order to monitor other traffic peccancies effectively, we also have designed the scheme to carry out traffic monitoring by manual.

First, it was to obtain two binary images from segmenting image by two thresholds. Second, erosion, opening and closing were done to the two images according to some knowledge of the shape and location of the objects in the image that we have already known. Last, the edge information from the image segmented by a high threshold was put into the image segmented by a low threshold. It is the way to segment and discern circular objects accurately from the complex image and can greatly improve the accuracy rate of discerning.

When audience face these images, it is natural to invoke the memory of source images, and it is such basic memory or source images intention that produce the reaction and confrontation to Xu's works, spur his works to enter audience's habitual recognition of images, and combine thinking with image cognition to form new interpretation of images, as to highlight the dubiety of source images and to increase the possible reinterpretation of source images, but the artist's conceptual interference is not close-ended but discloses the mechanism of contemporary image reading: i.e. the interaction between image and audience, as result such works are the presence of artistic conception but the absence of artist and that artist doesn't stress the input of personal experience into the work, but looks for the methodology of image-construction and the combination of thinking methods for creating the entity of joint between image and language.

当观众面对这些图像时，很自然地唤起对原有图像的记忆，正是这种基本记忆或原图像意图的捕捉对许昌昌的作品产生了反作用和对抗，促使作品图像进入到观众的图像识别习惯中，将思考与图像认知结合，形成新的图像阐释，既是突出原图像的可疑性，又增加了对原图像的重新解释的可能性，但艺术家的观念介入并不是封闭的，而是敞开了当代图像阅读的机制：即图像与观众的互动性，这样的作品是艺术观念在场而艺术家缺席，艺术家不强调个人生活经验进入作品，而是寻求图像构成的方法论和思维方法论的结合，创造图像与语言切合的实体。
