I have the following code that worked well with OpenCV 3.4.1 and now is not working with OpenCV 4.1.0 and gives an error. I do not know how to adapt the code wi
In order to extract texture-based features; LBPs (Local Binary Patterns) are used in many background-foreground detection algorithms. It is easy to understand w
I'm developing a Python module, with OpenCV, that connects to an RTSP stream to perform some preprocessing on the video (mostly, reducing fps and resolution), a
I'm trying to convert an image from RGBA to RGB. But the conversion to RGB is adding padding to the image. How can I convert without the padding? Or how can I r
I would like to know the difference between contrast stretching and histogram equalization. I have tried both using OpenCV and observed the results, but I stil
I would like to calculate a couple of texture features (namely: small/ large number emphasis, number non-uniformity, second moment and entropy). Those can be co
I am trying to convert YUV2 frames generated by V4l2 to RGB. I was able to convert YUV2 to RGB cv2.cvtColor(im, cv2.COLOR_YUV2RGB_YUYV) using OpenCV. Currently
I have cloned https://github.com/akTwelve/Mask_RCNN and run the demo code. Everything works fine and runs correctly but the image processing part has incorrect
