Hello, with the recent update, in Opencv 3.4.3, the non-free algorithms such as SIFT and SURF are no more available. >>>importcv2>>>cv2.__version__'3.4.3'>>>cv2.xfeatures2d.SIFT_create()Traceback(mostrecentcall
然后,您可以运行以下 cmake 命令,确保根据您在上一节中找到的 NVIDIA GPU 架构版本设置 CUDA_ARCH_BIN 变量: $ cmake -D CMAKE_BUILD_TYPE=RELEASE \-D CMAKE_INSTALL_PREFIX=/usr/local \-D INSTALL_PYTHON_EXAMPLES=ON \-D INSTALL_C_E...
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...

Q: Why the packages do not include non-free algorithms? A: Non-free algorithms such as SURF are not included in these packages because they are patented / non-free and therefore cannot be distributed as built binaries. Note that SIFT is included in the builds due to patent expiration since...
