 Hi Tom, Thanks for your note.
 Re linking of edges: the info I was looking for was the linking of
 edge elements for blocks scenes, such as used in Gunnar's thesis
 (he does not describe his algorithm). I presume similar techniques
 have been used in other blocks programs (not including line following).
 None of your references was to a blocks program!
 Further, I was interested in connecting  long, linked edges into
 object boundaries. For blocks scene, this is easily accomplished
 by fitting straight lines and finding intersections etc. I was
 looking for a more intelligent way of connecting the segments,
 based on some notions of outside of an object and restrictions
 on the smoothness.   I know of no such attempts, do you?
 
 On color edges, I have been in touch with AJT. I was more interested
 in color "edges" as you defined it, and was looking for a program
 to see how you fitted the "moments" of three components. I have
 some trouble finding the moments in the output of Heuckel, and
 was looking for a short cut by looking at some existing program.
 
 I have some good results on linking Heuckel output in straight line
 segments for the tank scene. Connecting these segments into a complete
 boundary, however, seems to be tricky.
 
 Going to Maryland conf. tomorrow. Talk to you when I return.
 
 Ram.

 1. I will be up at AI lab, this Fri (Mar 14). Would like to
   see you for some time. Have some thoughts to discuss  and also some details to be cleared.
 2. Tried to load your lateral inhibition edge detector (local.5t),
   got some undefined globals using vision.11 and undeclared variables
   using a later version of vision. It is perhaps just a small bug.
   I was hoping to see its results on some images.
 Hope to see you on fri.
 Ram.

 Hi Tom,
 	I could use some of the Hand-Eye routines right away. Mainly,
 I like to use the picture file input and output routines. In the mean
 time I have written some of my own, but they are just quick hacks.
 I may come up to SU later this week. If someone can look into it
 before, it would make my job easier, else I will struggle with it then.
 Our paper got accepted to the Conf. at Maryland. No written paper is
 required. I think that I will go. Were  you planning on it too?
 Ram.

 Tom, I want to use some of the Hand Eye library routines and need
 their source files to compile here. I understand that Karl Pingle
 has left. Is someone else taking over his function and knows about
 such things?
 Your new Vision Language write up is much better. I still have trouble
 with data structures and details of what exactly does each operation do.
 Please send me a note if someone can help with the Hand Eye stuff.
 (If you have problems with Network mail, leave a note on the 
 Stanford system.)
 Thanks.
 Ram.
