Hello,

I have this cannyed image:(http://)

I would like to find the coordinates of the points in the frame of reference of the image that have the white colour (RGB approx higher than 190 190 190)

Thank you for your help!

Hi Berak,

This question has been similarly asked but not successfully answered. I would be enormously grateful if someone could give a hand on this. My academic life depends on it.

Kindly

Jacob

I want to find the corners of the image attached.

I tried finding the canny edges to make it easier as I was only left with the plank edges but Im not sure this is the best approach.( maybe drawing straight lines through the fainted edges and then find corners but I dont know how I could do it)

I am looking to find the 2 edges of this wooden plank

Code is:

import numpy as np
from matplotlib import pyplot as plt
from scipy import ndimage
from skimage import filter
import cv2

img = cv2.imread('/.../plank5.jpg',0)

edges11 = cv2.Canny(img,100,200)

edges22 = cv2.Canny(img,380,460)

plt.subplot(131)
plt.imshow(img,cmap='gray')
plt.axis('off')
plt.title('Gray Image', fontsize=20)

plt.subplot(132)
plt.imshow(edges11,cmap = 'gray')
plt.axis('off')
plt.title('Lower MinVal', fontsize=20)

plt.subplot(133)
plt.imshow(edges22,cmap = 'gray')
plt.axis('off')
plt.title('Higher MinVal', fontsize=20)

plt.subplots_adjust(wspace=0.02, hspace=0.02, top=0.9,
                    bottom=0.02, left=0.02, right=0.98)
plt.show()
