We are interested in grey-scale digitizing some pathology microscope slides for alignment with medical images. We have a Mac II, and are looking for two things: 1. Video Digitizer 2. Analysis software MacWEEK just put out a Graphics Arts supplement that lists many video digitizers, ther prices, resolution, etc. Two look inexpensive enough for our grant money to pay for: QuickCatpure ($995, 256 Grey levels, real time acquisition) MacVision ($399, same grey levels, real time acquisition) Both have 640x480 resolution. Anybody have experience with these? Is MacVision shipping and functional? Why is it $600 cheaper? The Supplement also points out two image processing software packages: Image Studio and Digital Darkroom. Do either of these allow you to do feature analysis, like area of a feature, histogram analysis, FFT, etc? Sure appreciate any info y'all have.

We received the QuickCapture board and software from Data Translation (617) 481-3700 and we are very pleased with it. It is very fast and the quality is superb (7 good bits). It allows different input video configurations, and we plan to hook up RBG and then ddigitize each. The input video line is software selectable. The interface is suggestive and allows the images to be displayed on the screen at about 7 frames/sec and captured and saved in TIFF format. Additional features will become available when their software is completed next month. I don't know the other board, but typically the lower prices translate into slower on-board clock times which translates into less than real-time capture. Also make sure you know how many bits are solid. 7 out of 8 bits is very good (i.e., the top seven bits do not fluctuate with a stable input image). phil...
