Question

Advantages and disadvantages of sobel edge detection

Answer 1

Another advantage of the Sobeloperator is it can detect edges and their orientations. ... Overall, the Sobelmethod cannot produce accurate edge detection with thin and smooth edge. II) Canny Edge Detector. With Gaussian filter, any noise present in an image can be removed.

Answer 2

The main advantage of sobel edge detection is it is simplicity and the disadvantage was the signal to noise ratio.

Explanation:

• Sobel operator is its simplicity which is because of the approximate gradient calculation.
• Canny edge detection has greater computational complexity and time consumption because sobel operator it is more beneficial compare to canny edge detection.
• Another advantage of the Sobel operator is it can detect edges.
• There are some disadvantages are present in the Sobel method.
• The Sobel operator it is otherwise called as Sobel Feldman operator or Sobel filter.
• It is used in image processing and computer vision, particularly within edge detection algorithms where it creates an image emphasising edges.
