Description: Image alignment is a process of matching one image called template (let s denote it as T) and another image I (see fig. 1). There are many applications of image alignment, such as tracking objects on video, motion analysis and many other tasks of computer vision.
In this article we will implement these two algorithms in C language using Intel OpenCV open-source computer vision library as base for our implementation. We also will try to compare these two algorithms and will see which one is faster.

Description: In this project we have implemented a method for recognition of Printed Characters by extracting some features from the gray scale image using a Bank of Gabor Filters. In this project we initially segment the given word image into words and words into characters. We apply these characters to a bank of Gabor Filters .From the output of these Gabor Filters we extract features namely normalized Centroid ,Normalized area .We form a vector using these parameters and then compare these vectors with the reference vectors which were computed earlier using reference characters. Finally we print the character corresponding to the reference vector which is closest to the computed vector. - In this project we have implemented a method for recognition of Printed Characters by extracting some features from the gray scale image using a Bank of Gabor Filters.

Description: 为了解决光谱恢复对图像匹配高精度的问题, 提出了一种高精度图像匹配算法———利用光流确定图像的运动场对图像进行匹配。该算法克服了传统的基于灰度匹配方法受图像插值精度影响的缺陷以及运算速度和精度的局限性。与基于MAD 块匹配算法和归一化相关系数块匹配算法进行比较, 该算法实现了图像序列高精度匹配, 而且硬件实现简单, 计算复杂度较低。-To address the spectrum of the resumption of high-precision image matching problem, a high-precision image matching--- the use of optical flow algorithm to determine the image of the stadium to match the image. The algorithm to overcome the traditional matching method based on gray-scale image interpolation accuracy by the effects of defects, as well as the speed and accuracy of computing limitations. MAD-based block matching algorithm and the normalized correlation coefficient to compare block-matching algorithm, the algorithm achieved a high-precision image sequence matching, and simple hardware implementation, lower computational complexity.

Description: 本程序主要四大功能特点:
1、继承了 YUVViewer 可以同时打开多窗口的特点；
2、继承了 Elecard YUV Viewer 可以进行两幅图像对比的特点；
3、增加了宏块信息显示功能；
4、增加了两图对比时同步帧跳转功能：
例如对于错误码流，不同的错误隐藏算法可能造成解码序列长度不同，这时要比较两个序列就很不方便。而该功能正是为了解决这个问题，即以另一序列的显示图像为标准，在当前序列中寻找与其完全相同的图像。 -Four main features of this procedure: 1, inherited YUVViewer can also open multiple windows of the characteristics 2, inherited Elecard YUV Viewer can be characterized by comparing two images 3, an increase of the macro block information display 4, increasing When comparing the two plans simultaneously frame jump function: for example, the error stream for the different error concealment algorithm for decoding the sequence length may result in different time sequences to compare two very inconvenient. And the function is precisely to solve this problem, that is another sequence of display images as the standard sequence search in the current image with exactly the same.

Description: an introduction to wavelets
-Wavelets are mathematical functions that cut up data into di® erent frequency components,
and then study each component with a resolution matched to its scale. They have advantages
over traditional Fourier methods in analyzing physical situations where the signal contains
discontinuities and sharp spikes. Wavelets were developed independently in the ¯ elds of mathematics,
quantum physics, electrical engineering, and seismic geology. Interchanges between these ¯ elds
during the last ten years have led to many new wavelet applications such as image compression,
turbulence, human vision, radar, and earthquake prediction. This paper introduces wavelets to the
interested technical person outside of the digital signal processing ¯ eld. I describe the history of
wavelets beginning with Fourier, compare wavelet transforms with Fourier transforms, state properties
and other special aspects of wavelets, and ¯ nish with some interesting applications such as

Description: It can detect human emotion from image. First it take an image, then by skin color segmentation it detect human skin color then it detect human face. Then it separate the eyes & lip from the face. Then it draw bezier curve for eyes & lips. Then it compare the bezier curve of eyes and lips to the bezier curves of eyes & lips that are stored in the data base. Then it find the nearest bezier curse from the data base & give that data base stored bezier curve emotion as this image emotion.
