%CORNERDETECTOR   Corner detector
%
% SYNOPSIS:
%  error = cornerdetector(image_in,method,sigmas,parameter)
%
% PARAMETERS:
%  method:     Method to use. One of:
%    - 'Harris':     Harris corner detector. PARAMETER is the kappa.
%    - 'ShiTomasi':  Shi-Tomasi corner detector.
%    - 'Noble':      Noble's corner detector.
%    - 'WangBrady':  Wang-Brady corner detector. PARAMETER is the threshold.
%  sigmas:     The sigmas for the Gaussian smoothing applied.
%  parameter:  The additional parameter used in the method, some methods
%              don't use this.
%
% DEFAULTS:
%  method = 'ShiTomasi'
%  sigmas = 2
%  parameter = 0.04 for 'Harris' and 0.1 for 'WangBrady'.
%
