Research direction
The issue requests adding contour analysis functions similar to OpenCV. Start by reviewing OpenCV's documentation for findContours and related functions (https://docs.opencv.org/4.2.0/d3/dc0/group imgproc shape.html). Investigate how JuliaImages currently handles image processing pipelines. Consider whether to implement native Julia algorithms or wrap existing C libraries. Check the issue comments for any prior discussion on implementation strategy. Look for any existing forks or branches that have started this work.
