SMART is a program that processes colour images. The size of the processed image, which is displayed on the computer screen, is 512x512 pixels (horizontal x vertical resolution). A pixel is each one of the elements generated from the digitalisation of an analogue image (the one obtained by the camera); therefore, it is the minimum image information unit. Logically, the greater the resolution (the number of pixels contained in an image) is, the higher the precision obtained. Nonetheless, a price must be paid. Higher resolution means that a greater volume of information will have to be treated, the computer will need more time to process it, whereupon a faster and more powerful machine will be required to make sure that no images remain unprocessed (otherwise, this would lead to a loss of information).
It should be underlined that great care has been taken to make sure that SMART treats high-resolution images without letting any images remain unprocessed. To attain this goal, mathematical algorithms and different digital image processing techniques have been used to reduce analysis time. This is the reason why SMART will not work to its full potential in computers that do not comply with the minimum requirements.

In order to run at its potential, SMART needs the system to fulfil some requirements:

1. Pentium II processor (preferably Pentium III or AMD K-7) with an Intel PCI chip set that supports and enables PCI-to-posted memory writes. Its hard Disk should have at least 10 Mbytes free for installing SMART, but it needs more free space to save zone definition, sceneries, tracks, results...

2. At least one available PCI 32-bit or 64-bit bus master expansion slot (the frame grabber will be installed here).

3. At least 64MB of RAM (for Windows 95, 98, NT and 2000), 128 Mb preferably.

4. A VGA that supports 800x600 and 32-bit true colour RGB display (1024x768 and 32 bits recommended for future versions). There is no need to have a graphic accelerator installed.
   

5. A video source (TV camera and/or video tape recorder:

   1. Camera: it should be a standard PAL or NTSC with a resolution of at least 400 lines. Infra-red cameras can also be used.

   2. Video-tape recorder: a quality image system should be used, like sVHS. VTR must provide TBC (Time Base Corrector).
      

6. An image digitising card: Data Translation, model DT 3153.

7. A software protection key (provided by Panlab, s.l.).

8. Two versions of the software: the full operative version (SMART), which allows complete image acquisition operations and data analyses, and a second version (SMART_DT), which only allows data analyses. (both provided by Panlab, s.l.).
   

NOTE: As has been said, a video tape recorder can be added to the system in order to reproduce experiments which have been previously carried out and taped. Besides, a second monitor other than the computer screen can be incorporated into the system.

Here is a detailed report of the system specifications :
