OCV_OPTION(OPENCV_ENABLE_NONFREE "Enable non-free algorithms" ON)第212行 OFF改成ON,否则后续编译成功但是运行SURF算法时会报错: error: (-213:The function/feature is not implemented) This algorithm is patented and is excluded in this configuration; Set OPENCV_ENABLE_NONFREE CMake option and rebui...
Hello, with the recent update, in Opencv 3.4.3, the non-free algorithms such as SIFT and SURF are no more available. >>> import cv2 >>> cv2.__version__ '3.4.3' >>> cv2.xfeatures2d.SIFT_create() Traceback (most recent call last): File "

光流算法(Optical flow algorithms) 人脸和目标识别(Face and object recognition) 表面匹配(Surface matching) 文本检测和识别(Text detection and recognition) 02如何部署OpenCV? 一般来说我们会使用OpenCV的C++和Python版本,所以下面分别对其安装进行介绍,以ubuntu系统为例。
换成了3.0版本之后，对nonfree模块测试的还不够，所以暂时还没有直接给出像之前2.0版本那样方便的nonfree库。而是放在了xfeatures2d头文件和xfeatures2d库中。xfeatures2d比nonfree多了实验性二维特征算法（Experimental2DFeaturesAlgorithms）。想在3.0版本中使用SURF的话，暂时需要自己对OpenCV进行编译。...
