Hi Gursheen,
I understand that you want to find the center pixel value of a 3x3 matrix, which represents a small image or a section of an image.
I assume that you have a 3x3 matrix, and you are looking to extract the value of the center pixel, which is located at the second row and second column of this matrix.
In order to find the center pixel value of a 3x3 matrix, you can follow the below steps:
Define the 3x3 Matrix:
First, create or define your 3x3 matrix. This matrix represents the image or image section you are working with.
% Example 3x3 matrix
matrix = [1, 2, 3; 4, 5, 6; 7, 8, 9];
Access the Center Pixel:
The center pixel of a 3x3 matrix is located at the position (2,2). You can access this pixel directly using matrix indexing.
% Access the center pixel value
centerPixelValue = matrix(2, 2);
Display the Center Pixel Value:
For verification, you can display or output the center pixel value.
% Display the value
disp(['The center pixel value is: ', num2str(centerPixelValue)]);
In this example, the matrix is predefined, but you can replace it with any 3x3 section of a larger image if needed.
% Example output
% The center pixel value is: 5
This approach can be generalized to any 3x3 section of a larger image, where you need to extract the center pixel for processing or analysis.
Refer to the documentation of "matrix indexing" in MATLAB to know more about accessing elements: https://www.mathworks.com/help/matlab/math/matrix-indexing.html
Hope this helps!
