【摘要】 随着大规模集成电路、计算机网络技术和多媒体通信技术的进步，图像技术得到了爆炸性的发展。数字图像处理已经成为工程学、计算机科学、生物学等各种学科学习和研究的对象，它广泛的应用在通信、宇宙探测、军事公安等方面。本课题主要是建立一种基于教学和科研综合型的图像处理平台，提供一套完整的且价格低廉的图像处理系统。 本课题将包括图像的摄入和保存、平滑、直方图、锐化、边缘提取、分析与描述、频域变化等一系列基本处理过程。为了理论联系实际，本课题还对指纹，文字等线条纹图像的识别进行了初步的探讨，其目的是构造自动处理某些信息的机器系统，以代替人类完成分类和辨识的任务，尤其是指纹识别对于安全保障，公安破案方面有很大的帮助。为了使计算机识别时能很快的提取关键特征，提高准确度，减少时空耗费，本课题在分析了多种传统的条件细化、模板细化、形态数学上的细化等多种细化方法的原理和优缺点后，提出了一种新的模板细化算法，该算法毛刺较少，避免了过度的腐蚀，同时具有良好的连通性。 本课题一方面在Windows操作系统平台上，通过人机界面的方式利用VC6.0对大恒VIDEO_PCI_XR卡采集后的灰度图像进行软件处理，另一方面对Matlab引擎库函数和数字图像处理系统的接口进行了研究和技术实现，从而在VC6.0环境中成功调用Matlab的图像处理函数，在时间和效果两方面和VC6.0的处理结果进行了比较。更多还原

【Abstract】 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 basic’ handling course of absorbing and preserving the image, image’s flat moving, intuitionistic picture, sharp changing, edge extracting, analyzing and describing the image and the change in the frequency range. In order to relate theory with practice, this task made an elementary research on the discrimination of fingerprint, character and some linear images else with the purpose of constructing a machinery system which can deal with some information automatically and can replace the human being to finish the job of classification and discrimination. And that system has a great help especially for the safeguard and solving cases. Aimed at advancing the speed of extracting the key characters, improving the veracity, cutting down the cost of time and space, this task put forward a new template thinning algorithms after analyzing the principle, disadvantages and advantages of many thinning methods including condition thinning, template thinning and thinning in morphology maths. This algorithm with good collection has less thin-hair, and avoid excessive erosion.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 V.C6.0 and make a comparison on time and effect with the result made in V.C6.0.更多还原
