Tria Image Processing Demo Program
 
Below you will find a link to download the Tria Demonstration program.  The program is fully functional with the exception of "Save" functions.  The demo program becomes fully activated following purchase and installation of the hardware security key.  This will allow you to test drive the program on example images and your own images.  (As an anti-piracy measure, the grid function has been locked on. This does not affect the image data.)

Blind deconvolution is "blind" because you are missing crucial information about what created the image.  Success depends on your knowledge of the imaging system and a certain amount of trial and error.   With you as the potential purchaser, there are two scenarios we would like to avoid:
  1. Your first attempt does not yield satisfactory results, and you are thus discouraged about the process.
  2. You purchase Tria, and it turns out that your images may contain too much blur, or too much noise, to be significantly improved.
To avoid these situations, use the Tria Demo to
  1. practice on the included examples,
  2. take the time and read through the help file, and
  3. apply the Tria's methods to your specific images.  Start with small images to make the processing easier.

You can also use the images on this website for practice.  However, keep in mind that these images may have been reduced in size and compressed.

With apologies to Linux users, Tria currently runs on Windows (XP, Vista and "7", 32 and 64-bit versions) machines only. The program is robust, and includes examples and an extensive help file. I recommend using a machine with 1 GB of RAM for operating on images smaller than 1024 by 1024 pixels, and 2 GB of RAM for larger images. (Also increase your paging memory to the maximum level.) Image processing in any form is computationally intensive, so a fast processor helps.  Tria does operate on Apple machines running special software such as Parallels, but we do not have an Apple version of the software.

Note: Tria will most likely still run on Windows 2000, but we no longer have a machine to test it on. 


Download the latest version of Tria by clicking:

Download Tria Demo Version 2.8.09 (standard)


After download, unzip the file and run the TriaSetup/Release/TriaSetup.msi program.


This package includes the executable, and the help file.  Also download the Tria ImagePack1,  which contains the example images and a starter set of SeDDaRA reference images.  Unzip the ImagePack in the Tria Application folder after installation.

We have created a new pack of images.  Tria ImagePack2 includes a set of fractals that can be used as reference images for AstroPhotos.  The images come in a range of sizes from 512 to 4096 pixels a side.

Download Tria ImagePack2

New: We have created a new pack of reference images, sized 4096 by 4096.  Tria ImagePack3 includes several fractals that have proved beneficial for SeDDaRA deconvolution.  Most of the images are in 8-bit tiff format and will need to be converted to the Tria rtif format for use in SeDDaRA.


We have also created a 64-bit version of Tria.  Download this version only if you are using a 64-bit version of Windows.  The demo program has been tested on Vista and produced no errors.  However, we have experienced problems with the hardware security key in the past.  As far as we can tell, these problems have been resolved.

Download Tria Demo Version 2.8.11 (64-bit)

Special Note:  We noticed a web posting that stated the user had some difficulty running this program.  The demo has been downloaded over 2000 times with few reported problems.  However, this specific problem was not reported to us, and we could not determine the nature of the problem.  If the suggestions below do not resolve any difficulties you may experience, let us know.  We abhor inoperable software as much as you do, and will work with you to resolve it, even with the demo program.


Known Software Issues
  1. For XP installation, an error can occur concerning the driver "MSVBVM60.dll".  A user fixed this problem by upgrading the XP operating system to Service Pack 2.
  2. Some Tria functions only operate on certain types of images.  SeDDaRA reference images can only be created from grayscale images. 
  3. Tria uses the Microsoft software for opening up jpeg images.  Even though some jpegs are in 8-bit format, they are often opened as 24-bit color images.  After opening Tria does a check to see if the 24-bit image is actually grayscale and may convert it.
  4. Tria may have some difficulties processing larger images (greater than 2048 pixels per side).  This is typically a memory problem.  You may want to add more RAM to your computer, or reduce the image size.  We have verified that Tria can process a grayscale 4096X4096 image on a PC with 2 GBytes of RAM.  However, memory is allocated by the operating system and is often stingy.
  5. Area of Influence produces an error when the AoI size is larger than the image.  The error is valid, but the user should be warned.
  6. The demo version permits creating reference images that can be used with SeDDaRA, but not saving them.
  7. Tria 32-bit does run on 64-bit machines but the 64-bit version will not operate on a 32-bit operating system.
  8. Before version 2.4, Tria used elements from Microsoft Frameworks 1.1.  For some reason, version 1.1 is not included in later versions, and must be loaded independently.  You can download it from this page.
  9. With version 2.4, Tria uses only Microsoft Frameworks 3.5.  Some computers may have to be updated to this version.


Thank you for your interest in Tria Image Processing.
