查询词典 image area

Microscope and image analysis technique are adopted in 《JB/T 7990-1998》. The "grain size" tested by microscope is expressed by the "largest breadth" of the grain image. When the grain size is tested by image analysis instrument, the grain size is expressed by the diameter of a circle whose area equals the grain image's.

Detailed description has been given individually to the abnormal colours, lineament and circular structure and image features on the multi-geographycal information composite image. We have studied the ore control effect of circular and lineament structure to the multimetal ore, and come to the point that the Xianghualing region is a complex ore control area by circular and lineament structure.Therefore, we build a remote sensing imag model for ore field in the region. Within the circular structure, the northwest lineament crosses the northweast lineament and forms frames that control the metal ore distribution. According to the features of the found deposits and their coherent image, we conclude that there are two symbols for ore looking.

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.
