Detailed Description

Focus stacking.

Function Documentation

fstack()

function im = fstack	(		imlist,
			varargin )

Focus stacking.

SINTAX

im = fstack(imlist) im = fstack(imlist, opt1, val1, opt2, val2,...)

DESCRIPTION

Generate extended depth-of-field image from focus sequence using noise-robust selective all-in-focus algorithm [1]. Input images may be grayscale or color. For color images, the algorithm is applied to each color plane independently

OUTPUTS

im, is a MxN matrix with the all-in-focus (AIF) image.

INPUTS

images, is a cell array where each cell is a string with the path of an image.

Options and their values (default in perenthesis) may be any of

the following

nhsize, Size of focus measure window (9). focus, Vector with the focus of each frame. alpha, A scalar in (0,1]. Default is 0.2. See [1] for details. sth, A scalar. Default is 13. See [1] for details.
