【摘要】 图像复原技术具有广泛的应用领域,近年来已经成为国内外图像界研究的热点问题之一。对于运动模糊图像的高质量复原更是在安保监控,交通监控等领域中急需解决的问题本文主要研究了逆滤波、维纳滤波和Richardson-Lucy三种复原方法的原理,在有噪声(高斯、椒盐)和无噪声两种条件下分别对其做了匀速直线运动模糊恢复实验,并给出了图像质量评价的一些常用指标。实验结果表明：当图像中无噪声时,逆滤波复原的图像质量最高,其次为维纳滤波,RL方法复原的图像质量最低,但图像的清晰度仍然可以接受。在此试验结果的基础上,使用VC++设计开发了运动模糊图像复原系统并设计了易于实现的DSP板卡结构。该系统具有易于实现,运行稳定等优点,解决了目前同类系统不能使用多类算法对运动模糊图像进行复原的问题,具有一定的创新性,在同类产品中处于领先地位。该产品具有良好的商业化前景,如果投入到目前市场中,预期会取得较好的社会效益和一定的经济效益。运动模糊图像复原系统所涉及的知识面比较广,本文只对其中的三种关键算法作了讨论,并使用DSP硬件板卡加以算法的实现。以后将在系统功能的扩展、算法优化、DSP板卡设计等方面做进一步研究。更多还原

【Abstract】 The image restoration technology has the widespread application domain, in recent years already became one of domestic and foreign image research hot topics. Regarding the movement hazy picture’s high grade restoration is in the security monitoring, domains and so on transportation monitoring is urgently needed the solution the question.This article has mainly studied the liftering, the Weina filter and the Richardson-Lucy three kind of restoration method principle, in had the noise (Gauss, spiced salt) and does not have under the noise two kind of conditions to make the uniform rectilinear translation to resume the experiment fuzzily separately, and has given picture quality appraisal some commonly used targets. The experimental result indicated: When in the image does not have the noise, the liftering restoration’s picture quality is highest, next is the Weina filter, the RL method restoration picture quality is lowest, but the image clarity still might accept. In this test result’s foundation, used the VC++ designs to develop the movement hazy picture restoration system and to design the DSP board card structure which easy to realize.This system has easy to realize, movement stable and so on merits, solved the present similar system not to be able to use many kind of algorithms to carry on the restoration to the movement hazy picture the question, had certain innovation, was in the leading position in the similar products. This product has the good commercialization prospect, if invests into the present market, anticipated will obtain the good social efficiency and certain economic efficiency.The movement hazy picture restoration system involves the aspect of knowledge is quite broad, this article has only made the discussion to three essential algorithms, and uses the DSP hardware board card to perform the algorithm realization. Later in system function’s expansion, the algorithm will optimize, aspects and so on DSP board card design to do further studies.更多还原
