opencv 图像特征检测算法akaze

采用opencv2.1,实现了一个全新的背景切除高效算法(Using opencv2.1, implements a new algorithm for background removal efficiency )

CT拍摄拍摄一周，步进1度，360张投影图像，使用S-L滤波，滤波反投影FBP算法进行二维断面重建(CT filming for a week, step 1 degrees, 360 projection images, using S-L filter, filter back projection FBP algorithm for two-dimensional section reconstruction)

this programme for robots localisation uses the library opencv

opencv將彩色影像轉成灰階和canny並存檔(opencv convert color images to grayscale and canny and archive)

对图片中的人脸可以进行自动的标注，并显示出来。(The face of pictures can be automatic tagging, and displayed)

使用opencv提取图片中光斑的质心达到了亚像素级别(Using OpenCV to extract the centroid of the spot in the picture reaches sub-pixel level.)

此代码是基于OPENCV设计的关于图像细化的源代码，采集图像细化所用代码(This code is based on the image thinning OPENCV design source code, the code used to capture images thinning)

opencv2的入门级书籍，大家可以好好学习一下基础(Opencv2 entry level books)

说明：  programa libre cvv para cualquiera

说明：  通过knn分类算法识别魔方的色块颜色，加入是否识别成功判断，成功识别率比阈值法识别更高。有完整的备注(Through the KNN classification algorithm to identify the color block of the cube, the success rate is higher than the threshold method. Code has complete comments)
