I want to detect edges of shelf only to count number of shelves and count of partitions in shelf. I used OpenCV but it detects edges of all objects in images but I don't want to detect edges of other objects except shelves. Any idea how to do this.
# USAGE import numpy as np import cv2 def auto_canny(image, sigma=0.33): v = np.median(image) lower = int(max(0, (1.0 - sigma) * v)) upper = int(min(255, (1.0 + sigma) * v)) edged = cv2.Canny(image, lower, upper) return edged def main(imagePath): image = cv2.imread(imagePath) gray = cv2.cvtColor(image, cv2.COLOR_BGR2GRAY) blurred = cv2.GaussianBlur(gray, (3, 3), 0) auto = auto_canny(blurred) cv2.imshow("Canny", auto) cv2.waitKey(0) if __name__ == "__main__": main("images/shelf_data1.png")
