I have several =colleagues whoare interested in doing something similar on the PC platform and IT =looks tobe the best bet in the NIH Image price range (ie; free).  The Snappy =alsolooks to be the best bet for the application.  After checking the =archivesfor this list there seem to be several different opinions/experiencesregarding the Snappy.  Can someone with experience with the Snappy bring =meup to date?  If it doesn't work with the current version are there plans =forcompatability in future versions?  Are previous versions which the =Snappy wascompatable with (?) still available?  I have also looked at the =miroVideoVideo DCI plus and the Reveal Video Artist packages.  Any info regardingthese or other framegrabbers would be invaluable.  How about the macrolanguage?   Can acquisition and stack functions be macro'd (I use stackfunction in NIH Image to compare before and after treatment pictures to =showchanges in posture)?In my personal opinion, ImageTool is a great product (but then again, I =wrote it). As for the Snappy, I continue to be amazed at the quality of =the pictures it acquires.  For the price, you cannot beat it.  As for =whether or not it will meet your needs, that depends on what they are.  =As for options, ImageTool currently supports the DT3155 card, and the =next release (due real-soon-now) adds support for the 3152 and support =for both NT and Windows 95.  We have been working with Coreco and =Matrox, and hope to add support for their cards not long after the next =version of ImageTool is released.Regarding the Snappy, the current version of ImageTool does not work =with the Snappy.  We have determined that the fault lies with the Snappy =itself, nevertheless we have modified ImageTool to make the Snappy work.Our macro language is very simple right now, mainly to be used to =automate multi-step processes.Don------------------------------Date: Thu, 1 Aug 1996 21:24:09 -0700From: Don Wilcox To: "'ImageTool List Server'" Subject: RE: Automatic thresholding "hump" sizeMessage-ID: <01BB8068.30EFDA00@slip58.xroads.com>Recently in IT-List----------I just got IT and am using the 'Find Object' command and auto-selectto identify objects.  IT asks what the 'hystogram HUMP' size is.  I canchange this value,  and identify different object but do not know what =the'hump' size really is.  I could not find any information on this in thehelp, Does anyone know what it is?        Thanks for any help!The hump size defines the range of values that must be alternately the =same, or different, in order for the algorithm to recognize a change in =the histogram.  The algorithm basically works as follows.  First, a =histogram is computed of the area to be evaluated.  The histogram is =scanned linearly, looking for humps and valleys of the given size.  All =pixels with gray values in a given hump are reassigned the median value =in that hump, all pixels in valleys are trned white.  This thresholded =image is what is used to identify objects.  By changing the hump size, =you can experimentally change the sensitivity of the algorithm.

Then I compiled it with bc45 (not bc4.52). But when I compiled the it.cpp about serval hundreds lines,bc45 reported one error and stoped with no further infomation.Then I checked it.ide, it seemed that there are short of some source file.From the IT's introduction, the source file are also included in /pub/it.Please tell me how to solve the problm. Another,I use VC 4.0 much more than BC.I devolop OCX for other software now . I compare OCX with IT's idea ,find their goal in some aspect to be achived  are same .Maybe use some tech independ of language,it have more advantages.

After the selection of the Area of  Interest  by  the MagicTracker, our Plug-in (ELFO.DLL) detects strips on  bitmap image,  computes the area and the position of individual strips  and send it to the Result Window.  I plan to continue with: a)  Direct acquisition of image by the MCI-based frame grabber (I have     Intel Smart Video Recorder).b)  Testing and improvement of the strips detection using the more     sophisticated algorithm.c)  presenting of results of detection by the graph with the possibility of     the interactive work.  Therefore I would appreciate the answer to the following questions:1) How  can I exploit my 16-bit DLL for image acquisition in 32 bit    environment (I have heard something about THUNKING, but I have no    experiences with it). Can anybody give me the reference to the problem    of thunking or  the suggestion how to solve the problem of 16-bit MCI    driver in IT project. Solving of this problem can make  available     for IT users the really broad range of frame grabbers.2) Exists there the set of test images for the gel analysis to verify my    ELFO algorithm performance? (eventually comparing with some other similar    programs)?ThanksZoltan-------------------------------------------------------------------Dr. Zoltan Tomori, Institute of Experimental Physics,Slovak Academy of  Sciences, Watsonova 47,Kosice, SlovakiaPHONE:(4295) 762240, FAX:(4295)6336292  E-mail:tomori@linux1.saske.sk--------------------------------------------------------------------------------------------------Date: Thu, 8 Aug 96 15:33:48 BSTFrom: elrn@lut.ac.uk (R.

Because Istarted counting there this is why I never got over my 7-9 objects. Am Idealing with some predefined area of interest? If so, how can I countthe whole image?
