I am trying to improve my webcam based OpenCV mouse controller for disabled people (MFC C++ application): https://preability.com/face-controlled-mouse ...
I'm using the Lucas-Kanade sparse optical flow method where I'm finding feature points using the Shi-Tomasi corner detector Good Features to Track. H ...
I use opencv to calculate optical flow between 2 images (frame_t and frame_t+1). Then I want to use optical flow to warp frame t to get warped_frame_t ...
Any expert on opencv to help!! I need to draw the arrows to visualize the optical flow of lukas kanade method, i'm using arrowedline for this, but the ...
I have a 498-frames-long image sequence for which I calculated optical flow using cv2.calcOpticalFlowFarneback. Therefore now I have 497 vector maps r ...
I'm a beginner in python and raspberry pi and for a school project we're using a raspberry pi 3 and a camera module (fixed) and the idea is when u mov ...
I am trying to differentiate between camera motion and tool motion in a surgical video. I have tried optical flow using opencv farneback and pass the ...
I have been playing around with optical flow algorithms in python, and would like to apply them on the famous Yosemite sequence (a sequence of 15 fram ...
I am trying to understand some computer vision topics. One main difference I observed between these two is that In optical flow, the 2nd image is ofte ...
I need to take the output flow (shaped (cols,rows,2)) of a dense optical flow calculated through this: flow = cv2.calcOpticalFlowFarneback(im0, im1, ...
How do I perform Optical Flow on a set of images? I want to read multiple images and perform Optical Flow (Lucas Kanade) on them. However I get solut ...
I work on master's dissertation and I am looking for an method of calculating optical flow for pedestrian detection or pedestrian tracking based on op ...
so I'm currently detecting and localizing an object between two subsequent frames, and due to the nature of the localization algorithm I'm employing, ...
I am working on a hardware-based solution ( without GPU) for dense optical flow to get real-time performance @ 30fps with decent accuracy. Something c ...
I'm trying to get the amount of motion by calculating the optical flow magnitude between two images (in Python 3.7 and cv2 v4.0). But passing the same ...
I'm running the optical flow tutorial from opencv and the direct problem is the calcOpticalFlowPyrLK produces the error (-215:Assertion failed) img.de ...
I am working on human motion prediction. I should predict the movement of the human's hand. I use optical flow to detect the motion in a real video an ...
I have a video and I need to simulate frames using Optical Flow; i.e. having a frame and the Optical Flow that represents the pixel translation for th ...
I got stuck with a strange behavior, trying to initialize NVENC in ME-only mode. OpenEncodeSessionEx() always fail with #15 - "This indicates that an ...
