Design Of Video Image Capture And Process System Based On VC++6.0

Digital image technology has become an important source for human to accessinformation，because of the advantages of its large amounts of information，convenient of processing and transportation，and a wide range of applications．Theapplication of video image processing technology mainly includes the field of digitalbroadcasting， consumer electronics， video surveillance， medical imaging anddocument image processing．These products have a common technical basis：acquisition，display，processing and network transmission of video signal．In thispaper，the basis of this technology for research and design，closely linked to the hotspots of market consumption，with a strong technology extensionality．This thesis，after analyzing the general function and introduction of planningoverall designing of digital video system，focuses on the design of the variousparts．Design is mainly divided into two parts：The first part is video signal acquisition and display．This section is based on theVFW platform design，the API function provided by VFW software package offunction library provided by Microsoft for development，give full play to theadvantage of VFW function modules．The main work of this part contains: design andimplementation of video signal acquisition，buffer storage and display programs，thispart can achieve good results about image from camera input to PC real-time dynamicdisplay．Second part is video image processing．This part design based on the MFCplatform，and give full play to the advantages of the MFC library．The main work ofthis part contains：After briefly introducing the basic concepts and display principle ofthe digital bitmap，using MFC library to process digital bitmap，including theimplementation of image geometric transformation，color processing，smoothing andsharpening processing， finally to realize the video image processing platformminiaturization and convenient．The two parts in this article combine conveniently，implement acquisition andprocessing system of video image successfully．This way to develop video imagealgorithm is flexible，short design cycle，easy verification，has great advantage．...
