How to Draw a Bounding box over a Sobel Edge Detected object
I am detecting an object using the Sobel edge detector. If the object is present, I want to draw a bounding box over the object. To be more specific,
original image
sobel edge detected image
As you can see from the above image, I want to draw a bounding box over the detected object (i.e a plank in this case)
My code for sobel detection is,
import cv2
import numpy as np
img = cv2.imread('2.jpeg')
img = cv2.cvtColor(img,cv2.COLOR_BGR2GRAY).astype(float)
edge_x = cv2.Sobel(img,cv2.CV_64F,1,0,ksize=3)
edge_y = cv2.Sobel(img,cv2.CV_64F,0,1,ksize=3)
edge = np.sqrt(edge_x**2 + edge_y**2)
cv2.imwrite('messigray.png',edge)
