Filters to obtain blurred image

Hello, Please can u suggest some filtering techniques to obtain the blurred image in image processing other than Gaussian smoothening filter.

Any convolution of your image with any arbitrary kernel will result in blurring, e.g.

blurredimage = convn(yourimage, ones(5)/25, 'same');  %convolution with kernel of 1s.

Sir, I'm getting a blank white background when i pass my input image to the above given function.

Most likely your image was uint8, convn always return an array of class double. You can convert it back to uint8, or change the display range when you use imshow.

Anyway, the point of my answer is that you can use any convolution kernel of your chosing to blur the image instead of using a gaussian kernel.
