I am trying to do image processing using edge detection on several images. But it's working for all the images except the one I cropped and edited. Please help me. I really need to get this done.

% Display the original Image image = imread('stop.jpeg'); % Read Colour Image and convert it to a grey level Image myimage = rgb2gray(image); % Apply Sobel Operator % Display only Both Edges sobelhz = edge(myimage,'sobel','both'); imshow(sobelhz,[]); title('Sobel - Both Edges');

%Change the file name, save as some different name.
% Close Matlab and Restart it again
% Nothing wrong in the following code
clc; clear all; close all;
% Display the original Image
image=imread('safety night.jpg');
% Read Colour Image and convert it to a grey level Image
myimage=rgb2gray(image);
imshow(myimage);
title('Gray Scale Image');

Hi Shahrin,
I tried reproducing the issue,
One thing for you to note in your code is that the name of the image is different in the code. The file is named stopD.jpg, and your code is calling stop.jpeg.
So, that could be one cause of the issue. When I did try to reproduce I got an output which I have attached. Please verify that it is the correct output.
Hope this helps,
Cheers!
