Realization And Research Of Satellite Cloud Image Character Extraction And Image Display Technology

Recently, with the development of science and technology, the computer information processing has become the most important way for satellite cloud image processing. In remote sensing information, the satellite cloud image is one of the data source which includes abundant information, using image processing method extracted useful image information from satellite cloud image and judge the weather condition and change trend, that is the main work pattern in weather forecast field. So, it has become most important research direction for reasonable processing, analysis and application of satellite cloud image.In this paper, the general character of satellite cloud image was studied synthetically, on the basis of character analysis, the data format and pretreatment of original satellite cloud image information was studied, the common cloud image format and format transformation method was analyzed. Several efficient satellite cloud image pretreatment algorithm was studied, which includes image histogram enhancement, noise processing, etc, improve the quality of satellite cloud image and provide better guarantee for continuous processing and analysis. In addition, for observe the satellite cloud image better, the cloud image display technology and color processing technology was used, and the better and more direct observe way were provided.In this paper, choose the weather satellite cloud image as the research object, base on the edge and shape character extraction method, the image character extraction and display processing technology was studied, consider the abundant image and traditional method for reference, aim at character of satellite cloud image, using several satellite cloud image processing method adapt to the special image, which includes gray processing and fake color processing, three dimension processing, edge detection analysis, texture character analysis, threshold processing, and GVF model, etc. Base on the satellite cloud image theory knowledge and image processing method, combine with software engineering design method, the satellite cloud image processing software was designed, which achieved better experiment result. The experiment proves that the task has certain theory value and practical value.
