	Test Program README for XVISION.
  =============================================

These programs demonstrate most of the XVision libraries that are 
included in this release.  

grab_single:
	uses the Image class and the Video class to grab an image 
	and write it to a pgm file.

show_live:
	builds on grab single, demonstrating how to use the xvision
	classes for display of live video streams through XWindows.

linetest:
	shows how to use Edge trackers to track along lines.

cornertest:
	demonstrates one of the composite features that can 
	be built with the xvision framework, the Corner, synthesized 
	from two lines constrained to meet.

Blobtest:
	demonstrates simple region tracking using the BlobThreshold class.

ColorBlobTest:
	demonstrates color based region tracking using the BlobColor class. 
	 
SSDtest:
	demonstrates window based SSD tracking using Greg Hager's SSD algorithm.


These programs should have compiled when you built the system, 
as described in the README in XVision's root directory.  To get a list of 
the options you can use to run them, run the program with a -help
flag, or any other unrecognized string.     

As always, please direct any comments to hager-greg@cs.yale.edu or 
cantor-christopher@cs.yale.edu.  We will be happy to answer any questions 
or help you get your copy of xvision running on your system.  We especially 
want to know any problems you have or bugs you find.  Your feedback 
helps us improve the XVision package.
