Version	Published	Release Notes
1.6.0.0	28 Apr 2014	1 Robustness of closed contour fitting is dramatically improved by smart initialization (see InitialCircle.cpp). 2 Line fitting is compared to Hough transform and RANSAC least squares. 3 Circle fitting is compared to circle Hough transform.	Download
1.5.0.0	24 Mar 2014	New features in AGSM version 2.2: 1 We made the AGSM Canvas app more robust by smart initialization and image padding. 2 Only one app for both 64-bit Windows and 64-bit Mac.	Download
1.4.0.0	21 Mar 2014	New features in AGSM version 2.1: 1 We added the AGSM Canvas App, which is an interactive software.	Download
1.3.0.0	21 Mar 2014	Fixed some typos in PPT.	Download
1.2.0.0	20 Mar 2014	1 We added the line fitting and circle fitting packages. 2 We re-implemented GVF in C++/MEX to make it much faster. 3 We implemented Bresenham algorithm in C++/MEX to generate points on a line. 4 All force/torque computations in C++/MEX.	Download
1.1.0.0	28 Sep 2012	changed the description	Download
