removing connected component
显示 更早的评论
How can I remove a connected component from an image of particular length?
Actually I am processing some images in which there is a connected component in the form of an arc, which starts with the start of image top and ends where image ends. its length is equal to or greater than the image height.
please help me in doing this

You can use ismember(), as shown in my BlobsDemo image segmentation tutorial: http://www.mathworks.com/matlabcentral/fileexchange/25157 First identify the index of the blob you want to eliminate. It can be based on its area, shape, perimeter, MajorAxisLength, or whatever. Then use ismember to get a labeled image without that particular blob.

Easy. Simply set everything to zero
labeledImage(:) = 0;
Now all components are gone. But what good is this to you?

That was it. All connected components will be erased once you execute that code.

This is not an "Answer" for Khawaja. It does not address his original question at the top at all.
