Subject:      Images recording 

     Hi everybody, 
          I'm working with a b/w video camera and I would like 
     to record my images on magnetic tape. Normal VCR are 
     equipped with automatic gain control (AGC) and other proces- 
     sing features which are disturbing in my case. I would like 
     to know if anybody knows the name of a company offering VCRs 
     not equipped with these features and specially suited for 
     scientific recording of images. 

     Thank you!

Subject: Re:  Yet ANother Image Proc. Toolkit 

The info in a recent Vision-List about Bristol's image Toolkit was 
interesting and worthwhile to announce on Vision-List.  However, there 
seem to be quite a few of these beasts floating around (esp. in 
academia), some of which are public domain (i.e., free, no maintenance, 
maybe some documentation), some of which have been pseudo- 
commercialized, some of which have been commercialized, etc.  Perhaps 
Vision-List would be a good conduit for compiling a list of the known 
image toolkits and their availbility status.  If you can find a willing 
compiler (i.e., a human) who would edit the responses sent in by 
Vision-List readers, it would probably be a very good service to the 
Vision community (as you might guess, this implies I am not 
volunteering, but perhaps a call for a volunteer in a Vision-List 
announcement might succeed).

[ I agree that this would be worthwhile.  Those with information, please 
  post the information, and I will repost.  In particular, specify: the  
  language, target system and portability, scope of routines, copyrights,  
  support and maintenance, responsible person(s) to contact, extent of  
  constructs (e.g., image processing, region-based, abstractions for  
  object description, etc.), and (if appropriate) the cost of the system.

Subject: Perception data wanted 
Keywords: sensory input references 
Organization: Telecom Research Labs,IPF,Melbourne, Australia 

Is the following sentence meaningful? 

	"Unimpaired humans receive XX% of all sensory input visually." 

If it is: 
	  a) what is the value of XX? 
	  b) how is this determined? 
	  c) what is the standard reference on this? 

If not: 
	  a) what _can_ be meaningfully said in this context? 
	  b) what are the issues which complicate such estimates? 
	  b) what is the standard reference on the relative 
	     importance of the different senses? 

Please reply by email. 
I will summarize responses. 

Thankyou,

I am doing research in exploiting human visual systems characteristics for 
better image generation and compression. If you are doing research on related 
topic or one of the following topics : 
_ Image segmentation using human visual properties and applications in image 
compression. 
-The use of visual models for better image generation. 
-The use of spatial and temporal characteristics of the visual system to 
enhance image quality and update rates. 
     Contact me, regarding your most recent publications in any of the above 
topics. Thank you
