Hello Arpit<br><br>If you are referring to this method: <a href="http://en.wikipedia.org/wiki/Difference_of_Gaussians">http://en.wikipedia.org/wiki/Difference_of_Gaussians</a><br>you can try to simply use two RecursiveGaussianImageFilter with two different sigmas, and substract the smoothed images with DifferenceImageFilter.<br>

Hey,<br>

month...I wanted to know how can we implement a difference of gaussian<br>
filter("NOT" DifferenceOfGaussianGradientFilter) on a grayscale image.<br>
<br>
