Does anyone has the codes of the Sobel edge technique？

The Sobel edge technique is extensively utilized in the microscopic imaging, computer vision,and image processing，please refers to the articel(https://doi.org/10.1002/apj.2745). Thank you.

I'm not going to pay money to research your question on your behalf.

See fspecial(), imfilter(), edge()

Otherwise, you're going to have to elaborate on how you intend to apply the tool.

Hello Albert,

I do not have much knowledge in the Sobel Edge Detection Technique. So, I cannot directly help you with your code. However, I can guide you on how you can achieve this.

To my knowledge, you can do using sobel MATLAB function. I have attached relevant documentations below which can give you a better understanding on this.

• Generate Code to Detect Edges on Images Using Sobel Function
• Sobel Edge Detection Algorithm with Computer Vision Toolbox
• Find edges in 2-D grayscale image

There is a Geeks for Geeks page for this, you can check this too:

• MATLAB – Image Edge Detection using Sobel Operator from Scratch

Hope this helps.

Thank you so much for your help, could you send me a example code for it which can make easily understand.
