OpenCV NumPy

This function reads an image from a specified path, converts it to a grayscale image, and then applies thresholding to get a binary image. After that, it uses OpenCV's findContours function to detect contours in the image and draws them on the original image. Finally, it displays the image with contours.

OpenCV NumPy

This function uses functions from the OpenCV library to detect rectangular regions in an image, assuming these regions are squares. It first converts the image to a grayscale image, then creates a binary image using thresholding. It then finds contours in the binary image and filters out possible square contours. Finally, it calculates the bounding rectangles for each square and draws these rectangles on the original image.
