The Transformation Domain Processing Of The Minitype Digital Image Disposal System

With the progress of large-scale integrated circuit, technique of computer network and technique of multimedia correspondence, the technique of image has been developed explosively. The disposal of digit image has become the study and research subject of engineering, computer science and biology and has been applied to the correspondence, war, public security and exploring in the universe. This task is aimed to construct a platform based on the teaching and scientific research for disposal of image and to offer a complete and low-priced system for disposal of image. This task includes a series of speedy arithmetic analysis and their programme implement in frequency domain after spatial domain. It also includes image enchancement in the frequency domain that is several frequency-domain filter. At last the task includes the arithmetic of wavelet transformation and its application in image copression.On one hand, this task made use of VC6.0 to deal with the gray image which was collected by Daheng VIDEO_PCI_XR CARD on the Windows operation platform through the way of interface; on the other hand, it made some researches and the realization of technique on the meeting joint of the function in Matlab engine and the disposal system of digit image. As a result, it can successfully transfer the image of Matlab to handle the function in VC6.0 and make a comparison on time and effect with the result made in VC6.0.
