Binary Image Contour Detection

This function converts the input image to grayscale, applies thresholding to obtain a binary image, and then finds contours in this binary image.

Technology Stack : OpenCV

Code Type : Image processing

Code Difficulty : Intermediate

                
                    
def find_contours(image, mode='default'):
    # Convert the image to grayscale
    gray = cv2.cvtColor(image, cv2.COLOR_BGR2GRAY)
    # Apply thresholding to get a binary image
    _, thresh = cv2.threshold(gray, 127, 255, cv2.THRESH_BINARY)
    # Find contours in the binary image
    contours, _ = cv2.findContours(thresh, mode, cv2.CHAIN_APPROX_SIMPLE)
    return contours
