2D CONVULUTION OF LETTER E-3D PLOTS.JPG

This is my required work to convolve letter E with small square, Circle and Large square and by doing this I have to draw their 3D plots. I don't know how to start this. I used conv2 command but its not working directly.

Two points you may have overlooked.

You need to do it on monochrome images, not color. So extract the color channels and do it one color channel at a time.
You need to cast the uint8 to double before you pass the array into conv2.

I need to do the above task through convolution. It would be helpful to me if you teach me how to start writing this code. It looks very difficult for me. Plz help me

在 MATLAB Online 中打开

windowSize = 9;
kernel = ones(windowSize)/windowSize^2;
blurredImage = conv2(double(grayImage), kernel, 'same');
surf(blurredImage);
colormap(gray(256));
