[Other resource] 采用小波进行图像消噪

Description: 数字图像在产生过程中经常会受到噪音污染。因此，对于数字图像应该对其进行去噪音处理。在传统的基于傅里叶变换的信号去噪音方法中，可以使得信号和噪音的频带重叠部分尽可能的小，这样就可以在频域通过时，不需改变滤波方法而将信号和噪音分隔开来。但是，如果信号和噪音的频域重合时，用该方法进行噪音处理的效果就比较差。-digital image in the selection process will be subject to regular noise pollution. Therefore, the digital image should be carried out to deal with the noise. Based on the traditional Fourier Transform method of signal to noise, can result in a signal and noise bands overlap small as possible, so it can be adopted in the frequency domain, the need to change methods of filtering the signal and noise to separate. However, if the signal and noise in the frequency domain coincidence, the method for dealing with the effects of noise on the relatively poor.

Description: 直方图均衡能有效地对数字图像进行增强处理，其主要缺点是处理后的数字图像大量损失灰度层次，且增强力度不够．提出了在子块部分重叠直方图均衡的基础上，引入保留灰度级直方图均衡理的方法，使得处理后的图像对比度得到较大的增强，又不损失灰度级，且相邻像素间灰度过渡平，图像柔和、真实．针对处理后方块效应严重的图像，依据人眼的视觉特性和数字图像数据的特，提出了自适应行列分比例方法来有效消除块效应．-Histogram equalization can effectively enhance the digital image processing, its main drawback is the treatment of significant loss of gray-scale digital image level, and strengthen weak. Proposed overlap in the sub-block histogram equalization, based on the introduction of gray-scale histogram equalization reserves management approach, making the processed image contrast is greatly enhanced, without loss of gray-scale, and the adjacent pixels transition level grayscale, image soft and true. Dealing with the serious effects of the image block, based on human visual characteristics and the characteristics of digital image data, the percentage of the ranks of proposed adaptive method to effectively reduce blocking artifacts.

[Special Effects] Image-Alignment-and-Stitching

Description: This tutorial reviews image alignment and image stitching algorithms. Image align- ment (registration) algorithms can discover the large-scale (parametric) correspon- dence relationships among images with varying degrees of overlap. They are ideally suited for applications such as video stabilization, summarization, and the creation of large-scale panoramic photographs. Image stitching algorithms take the alignment estimates produced by such registration algorithms and blend the images in a seam- less manner, taking care to deal with potential problems such as blurring or ghosting caused by parallax and scene movement as well as varying image exposures. This tu- torial reviews the basic motion models underlying alignment and stitching algorithms, describes effective direct (pixel-based) and feature-based alignment algorithms, and describes blending algorithms used to produce seamless mosaics. It closes with a dis- cussion of open research problems in the area.
