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. Platform: |

Description: 本项目名称是：基于FPGA的指纹识别模块设计。
主要内容为：本模块采用xilinx公司的Spartan 3E系列XC3S500E
型FPGA作为核心控制芯片，通过富士通公司的MFS300滑动式电容指纹传感器对指纹图象进行提取，然后对提取的指纹图像进行灰度滤波、图像增强、二值化、二值去噪、细化等预处理，得到清晰的指纹图象，再从清晰的指纹图象中提取指纹特征点，存入外部FLASH作为建档模板。指纹比对时，采用同样的方法获得清晰的指纹图像，建立比对模板，然后将比对模板与建档模板利用点模式匹配算法进行比对，得出比对结果。该模块利用嵌入式软核实现系统的管理，利用硬件实现指纹识别，保证了系统功能的完整性与识别的正确性。该识别模块可用于门禁、考勤、安检、保险箱柜等很多方面，也可和计算机等设备联机使用，满足各个方面的不同需求，因此它的设计具有很广泛的应用前景和市场价值。
-The project name is: FPGA-based fingerprint identification module design.
The main contents are: the use of this module xilinx s Spartan 3E Series XC3S500E
FPGA-based control chip as the core, through the MFS300 Fujitsu fingerprint slide sensor capacitance extraction of the fingerprint image, and then extracted gray-scale fingerprint image filtering, image enhancement, binarization, denoising Second, refinement, etc. pre-treatment have been given clear fingerprint image, and then a clear fingerprint image from the extracted fingerprint feature points, into the external FLASH file as a template. Fingerprint matching using the same method to obtain a clear image of the fingerprint to establish than the template, and then will be the template file templates and the use of point pattern matching algorithm than the right, than the results obtained. The module is the realization of the use of soft-core embedded system management, the use of fingerprint recognition hardware implementation Platform: |

Description: For the detection of sign each frame is analysed.
First the image is Converted into gray scale image and then threshold is performed.
Then by using blob analysis portion of red part is extracted.
Then this extracted part is compared with each template.
If the template is matched with extracted part then a rectangle is drawn at the location of extracted part in that frame.
In this way rectangle is drawn at all the frames and at the end all frames are played using implay video command.
Recognition and display the Name of Traffic Sign
Now when the template is matched with extracted blob this is done by using correlation.
Each template is matched with extracted blob by correlating each template and extracted part.If there’s exactly or 50 match then a check is assigned that its completely matching with the extracted blob sign.
Now template is recognized Now the name of recognized sign is concatenated with the red sign.
Image of Sign is Deigned and will be provided With the Source Code.
