Concrete pipelines and working scripts using OpenCV 4+ pythonic API: one project builds HSV + color masks, erosion/dilation, Canny edges and HoughLinesP to detect left yellow and right white lanes; the second uses grayscale, Gaussian blur, frame differencing, thresholding and contour area filtering to produce bounding boxes for moving cars. Code and examples live on the uploader’s GitHub and the methods demonstrably detect lanes and vehicles though lighting changes cause failures, making parameter tuning essential.
