Machine Vision Research Sub-Tools

The tools contained in this section are less fixed in nature and may not have yet been released for use external to the group. These tools are in a state of flux and may be subject to change at any time, depending upon research requirements. We endevour to keep the most recent versions of proven algorithms up-to date but there is often a lag between the current reseach and inclusion of new techniques. Such techniques will however generally be available as executable demonstrations.

• Calib: calib_tool()

  This tool is used for the calibration of images via the estimation of the parameters of projective camera models. It controls a single graphical Tv structure and has access to the global stereo calibration structures via get calib and set calib buttons.

• Edge Geom: edge_tool()

  This tool is an iterface to the routines in Tina system for performing edge detection, edge based stereo processing and recovery of wire frame geometrical scene descriptions. The tool must be used in conjuction with the Stereo or Mono tools for input output and display and operates on the mono, left and right image global data structures, which can be viewed on their associated Tvs.

• Corner: corner_tool()

  The Corner Tool is an iterface to the routines in Tina system for performing corner detection and corner based stereo and temporal matching. The tool must be used in conjuction with the Stereo or Mono tools for input output and display and operates on the mono, left and right image global data structures.

• PMF Stereo Test: stereo_test_tool()

  This tool provides an iterface to Tina subroutines for the use of edge string based stereo algorithms. This tool should be used in conjunction with the stereo sub-tool and operates on the left and right image global data structures.

• Correlation Stereo: st_corr_tool()

  The Stereo Corr Tool provides an iterface to Tina subroutines for the use of image correlation based stereo algorithms. This tool should be used in conjunction with the stereo sub-tool and operates on the left and right image global data structures.

• Pairs: pairs_tool()

  The pairwise tool provides an iterface to the Tina subroutines for generic object recognition of 2D projected shape via the use of pairwise geometric histogrammes. This tool should be used in conjunction with the Mono sub-tool and operates on the mono global data structures.

• Matcher: matcher_tool()

  The matcher subtool provides an interface to the Tina subroutines for the location of 3D wireframe objects. It has associated with it additional Tv tools for scene and model display. This tool should be used in conjunction with the stereo, edge and corner tools and operates on the left and right image global data structures.
