How to explicitly access mjpeg backend for videocapture in opencv

由 家住魔仙堡 提交于 2021-02-08 05:15:15
问题 When I execute following: availableBackends = [cv2.videoio_registry.getBackendName(b) for b in v2.videoio_registry.getBackends()] print(availableBackends) I get ['FFMPEG', 'GSTREAMER', 'INTEL_MFX', 'V4L2', 'CV_IMAGES', 'CV_MJPEG'] . If I now try: print(cv2.CAP_FFMPEG) print(cv2.CAP_GSTREAMER) print(cv2.CAP_INTEL_MFX) print(cv2.CAP_V4L2) print(cv2.CAP_IMAGES) print(cv2.CAP_MJPEG) all work except the last one AttributeError: module 'cv2.cv2' has no attribute 'CAP_MJPEG' . How can I explicitely

问题 I am new to cmake. I have a project which uses dlib and opencv. They are defined as submodules which are in third_party folder. I want to link them to my main project which is 'node' with cmake but I could not achieved. I am sharing my project tree. I did with find_package(OpenCV) and target_link_libraries(recognition-node ${OPENCV_LIBS}) way but I need to compile from source without installing anything. At last, I just want to write 'cmake . && make' . ├── CMakeLists.txt ├── node │ ├── build

I downloaded the dependencies as shown here: http://docs.opencv.org/3.1.0/d3/d52/tutorial_windows_install.html While configuring cmake, the first thing it shows is: FP16: Compiler support is available A library with BLAS API not found. Please specify library location. LAPACK requires BLAS A library with LAPACK API not found. Please specify library location. The problem is, that I don't know how to specify the location. For the

问题 I am new to OpenCV, I need help removing the watermark from this image, I tried using inpaint but I want a more automated way of feature mapping and inpainting, pls help me with it. 回答1: If all your images are like this and have a watermark as shown in the question having a light gray watermark then a simple thresholding operation will work. import cv2 img = cv2.imread('watermark.jpg') _, thresh = cv2.threshold(img, 150, 255, cv2.THRESH_BINARY) cv2.imshow('Result', thresh) cv2.waitKey(0) cv2
