ismooth

Gaussian smoothing

out = ismooth(im, sigma) is the image im after convolution with a Gaussian kernel of standard deviation sigma.

out = ismooth(im, sigma, options) as above but the options are passed to CONV2.

Options

'full' returns the full 2-D convolution (default)
'same' returns OUT the same size as IM
'valid' returns the valid pixels only, those where the kernel does not exceed the bounds of the image.
