代码说明:

  均值滤波和中值滤波 图像是一种重要的信息源,通过图像处理可以帮助人们了解信息的内涵,然而在图像使用和传输过程中,不可避免会受到噪声的干扰,因此为了恢复原始图像,达到好的视觉效果,需要对图像进行滤波操作。根据噪声种类不同,可以采用不同的滤波方法,均值滤波是典型的线性滤波算法,能够有效滤波图像中的加性噪声,而中值滤波器是能够有效滤除脉冲噪声的非线性滤波器,但传统中值滤波去脉冲噪声的性能受滤波窗口尺寸的影响较大, 在抑制图像噪声和保护细节两方面存在矛盾。本文首先对不同均值滤波器在处理不同噪声方面的优缺点进行了分析,然后分别用中值滤波器和自适应中值滤波器对被椒盐噪声污染的图像进行了滤波操作,发现自适应中值滤波方法不仅可以有效滤波椒盐噪声,同时还可以有效地克服中值滤波器造成图像边缘模糊的缺点。(Mean filtering and median filtering)

    说明:  虚拟内窥镜关键技术研究 虚拟内窥镜技术(Virtual Endoscopy)是虚拟现实技术在现代医学中 的应用。它利用医学影像作为原始数据,融合图像处理、计算机图形学、科 学计算可视化、虚拟现实技术,模拟传统光学内窥镜的一种技术。它克服了 传统光学内窥镜需把内窥镜体插入人体内的缺点,是一种完全无接触式的检 查方法。虚拟内窥镜的研究旨在为医生提供诊断依据,还可应用于辅助诊断、 手术规划、实现手术的精确定位和医务人员的培训等。(Research on key technologies of virtual endoscopy virtual endoscopy (Virtual Endoscopy) is a virtual reality technology in modern medicine. It has made use of medical imaging as an original data, the integration of image processing, computer graphics, scientific visualization, virtual reality technology to simulate a conventional optical endoscope technology. It overcomes the traditional optical endoscope to be inserted into the endoscope body of the shortcomings of the human body is a no-contact inspection method. Virtual Endoscopy of the study was to provide diagnosis for doctors, but also applies to diagnosis, surgical planning, to achieve precise positioning of surgical and medical personnel training.)
