MATLAB: How we can amplify an image with nearest neighbour interpolation amplificationImage Processing Toolbox how we can amplify an image with nearest neighbour interpolation Best Answer Amplify?? you mean resize? if that's what you mean here is the codeIResized= imresize(I,scale,'nearest'); Related SolutionsMATLAB: When image is rotated its pixels get very low and image become very distorted If you're using imrotate(), try using the 'bilinear' or 'bicubic' interpolation option, instead of the default 'nearest' neighbor option. MATLAB: Does ‘imresize’ generate artificial pixel RGB values which are not contained in the original image Hi,Yes for interpolation methods like bilinear, bicubic. But if you want to avoid it.As suggested by Adam you can try interp2.I would also suggest something similar. The imresize has 'nearest' as it's Interpolation method. You can try that too. J = imresize(I, 0.5, 'nearest');This shrinks by factor of two using nearest-neighbor interpolation. This is the fastest method, but it has the lowest quality.
