function [coutmarked_img]=corner(varargin)
% CORNER Find corners in intensity image.
% CORNER works by the following step:
% 1. Apply the Canny edge detector to the gray level image and obtain a
% binary edge-map.
% 2. Extract the edge contours from the edge-map fill the gaps in the
% contours.
% 3. Compute curvature at a low scale for each contour to retain all
% true corners.
% 4. All of the curvature local maxima are considered as corner
% candidates then rounded corners and false corners due to boundary
% noise and details were eliminated.
% 5. End points of line mode curve were added as corner if they are not
% close to the above detected corners.
%
% Syntax :
% [coutmarked_img]=corner(ICT_anglesigHLEndpiontGap_size)
%
% Input :
% I - the input image it could be gray color or binary image. If I is
% empty([]) input image can be get from a open file dialog box.
% C - denotes the minimum ratio of major axis to minor axis of an ellipse
% whose vertex could be detected as a corner by proposed detector.
% The default value is 1.5.
% T_angle - denotes the maximum obtuse angle that a corner can have when
% it is detected as a true corner default value is 162.
% Sig - denotes the standard deviation of the Gaussian filter when
% computeing curvature. The default sig is 3.
% HL - high and low threshold of Canny edge detector. The default value
% is 0.35 and 0.
% Endpoint - a flag to control whether add the end points of a curve
% as corner 1 means Yes and 0 means No. The default value is 1.
% Gap_size - a paremeter use to fill the gaps in the contours the gap
% not more than gap_size were filled in this stage. The default
% Gap_size is 1 pixels.
%
% Output :
% cout - a position pair list of detected corners in the input image.
% marked_image - image with detected corner marked.
%
% Examples
% -------
% I = imread(‘alumgrns.tif‘);
% cout = corner(I[][][]0.2);
% [cout marked_image] = corner;
% cout = corner([]1.6155);
% Algorithm is derived from :
% X.C. He and N.H.C. Yung “Curvature Scale Space Corner Detector with
% Adaptive Threshold and Dynamic Region of Support” Proceedings of the
% 17th International Conference on Pattern Recognition 2:791-794 August 2004.
% Improved algorithm is included in “A Corner Detector based on Global and Local
% Curvature Properties”and submitted to Optical Engineering.
