Hello all,

I am a beginner here. I have been given a project in my college to extract edges of a car door. The edges are to be smooth and accurate. I used edge detection savitky_golay_filter and got an image as follows.

The original image: (reduced the size during upload)

Applied savitky_golay_filter at three different thresholds 40,167,240 and blended all the images to get most of the edges of the above image. After this I took only the red edges and converted the entire image to grey scale.

The below is the resultant:

Now the edges are not smooth and continous. How to smooth the edges so that I get sleek and continous lines?

I just changed the threshold condition

red_comp = rbgtest(:,:,1)>rbgtest(:,:,2) & rbgtest(:,:,1)>rbgtest(:,:,3);
windowSize = 10;
kernel = ones(windowSize) / windowSize ^ 2;
blurryImage = conv2(single(red_comp), kernel, 'same');
binaryImage = blurryImage > 0.5; % Rethreshold
figure(2),imshow(binaryImage)
