Is there any way to detect edge in this situation?
I try to detect edge using python. There are hundreds of algorithms for edge detection, however, the image is very obscure and unclear. The most serious problem is one edge is located at the local maximum value, but the other edge is located slightly shifted from local maximum value. Through the detailed examination, I found the other edge is located
I am trying to save frames from a webcam via Python and ffmpeg, but the video becomes way to fast
I get a stream of cv2 images from my webcam and want to save it to a video file. After playing a bit with cv2.VideoWriter() it turned out that using ffmpeg would provide more options and – apparently, following a few threads here on SO – lead to better results. So I gave the VidGear Python library a try, and
Trying to Count Faces Using OpenCV, Haar Cascades and Raspberry PI
So I have a project for a trail camera to count people entering the trail by detecting their faces. There isn’t any power available so I am stuck using a Raspberry Pi 3 B+ for power reasons. I am currently using opencv and Haar cascades to detect faces. My problem is two-fold. The first one is that my counter behaves
Create Voronoi art with rounded region edges
I’m trying to create some artistic “plots” like the ones below: The color of the regions do not really matter, what I’m trying to achieve is the variable “thickness” of the edges along the Voronoi regions (espescially, how they look like a bigger rounded blob where they meet in corners, and thinner at their middle point). I’ve tried by “painting

And for that, I would need the value my function returns through ssh. With a simple example : slaveScript.py masterScript.py I would like, for this example

Is it possible to create a random shape on an image in python?
I need to create some spots on an image. The spots are of irregular shape (mainly I was trying to add a big circle then trying to add smaller circles on the edges of the big circle so it gets an “irregular” circular shape). Here I just showed one circle in the example. As I have a directory full of
How to efficiently loop over an image pixel by pixel in python OpenCV?
What I want to do is to loop over an image pixel by pixel using each pixel value to draw a circle in another corresponding image. My approach is as follows: Looping this way is somewhat slow. I tried adding the @njit decorator of numba, but apparently it has problems with opencv. Input images are 32×32 pixels They map to
import cv2 not working in vscode but working in pycharm
I got import cv2 to work on pycharm but for some reason it does not work on my visual studio code despite doing the same thing I did with pycharm which was to pip install opencv-contrib-python on a virtual enviroment. I created a virtual enviroment in vscode and the file is part of my project file and I selected the
