OpenCV

问题 I'm struggling to understand why I cant get a "LIVE" feed from my IP camera. It appears that there is a buffer and it causes the frames to build up if not being read - and as each iteration of my code takes some time there is a backlog and it ends up being almost slow mo to whats actually happening. I found the below code which triggers a thread to do the reading of the camera on a loop to try and avoid this. But now i'm getting a "LIVE" feed for around 5 frames and then it stalls and shows

问题 Hello I'm currently running code that sends data from Python to JavaScript. Currently, because I'm not able to send data straight from the primary code I'm running, I am communicating between UDP Connections across two separate Python Files: I merged UDP Server Code with the Main Code I'm running which is an OpenCV Eye Coordinate Tracker. This UDP Server carries the Eye Coordinate data and sends it to the UDP Client which I have merged with the Websocket Server that is communicating with a

问题 I want to use openvino-opencv for my Qt ( Qt5.7.1 ) based project. I have downloaded and installed openvino411 (corresponding to opencv411) following the instructions here in windows10 https://docs.openvinotoolkit.org/latest/_docs_install_guides_installing_openvino_windows.html#Configure_MO. I write a .pri file to demploy the opencv in Qt: INCLUDEPATH += C:/openvino-411/openvino_2019.2.275/opencv/include CONFIG(release, debug|release):{ LIBS += -LC:/openvino-411/openvino_2019.2.275/opencv/lib

问题 Hi stackoverflow community, I have a tricky problem and I need your help to understand what is going on here. My program captures frames from a video grabber card (Blackmagic) which just works fine so far, at the same time I display the captured images with opencv (cv::imshow) which works good as well (But pretty cpu wasting). The captured images are supposed to be stored on the disk as well, for this I put the captured Frames (cv::Mat) on a stack, to finally write them async with opencv: cv:

问题 I have obtained an image after applying k-means with clusters = 3. Now I want to obtain 3 separate images on the basis of colours obtained after k-means. For example, consider the attached image. Now I need one image such that it contains only the blue square. One having the letter v and one with just the background Is there any possible way to do that using OpenCV and python. 回答1: The most general and simplest way to do it is using the three unique gray colors for each region. (Although I

问题 I want to change this background into the original black. This background is not pure black. Its values contain 1, 2 or 3. After using the following code I got the background value very near to black but not black. Although the background looks black img = cv2.imread("images.bmp") gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY) ret, thresh = cv2.threshold(gray, 0, 255, cv2. THRESH_BINARY) img[thresh == 5] = 0 kernel = cv2.getStructuringElement(cv2.MORPH_ELLIPSE, (5, 5)) erosion = cv2.erode(img,

问题 I'm developing a project (in Python) that does video processing using OpenCV. Now I'm planning to implement that in my android phone. I read that Qpython supports python on android. So is there any way to import third party libs like OpenCV in Qpython. Thanks in advance. 回答1: You can install opencv from qpython libraries(install from QPypi). QPython --> Libraries --> QPypi --> opencv-qpython --> install Use it as import cv 回答2: In Qpython3 there is a pip program (not sure if on qpython too)
