FORident Software is pleased to announce the release of HemoSpat v1.9.1 for Mac OS X 10.9-10.10, Windows 7, Windows 8, and Windows 8.1. This update is available to all registered users.

This release addresses a couple of issue discovered during a Math & Physics for Bloodstain Pattern Analysis course at the Ontario Police College earlier this month. Thanks to Irv for reporting the issues and testing the fixes!

The fixes focus on drag & drop of images into a project – due to timing issues, some images could be duplicated – and on zooming of images. The memory requirements for displaying images was reduced and the speed of zooming of images was dramatically improved.

FORident Software is pleased to announce the release of HemoSpat v1.9 for Mac OS X 10.9-10.10 [64-bit Intel], Windows 7, Windows 8, and Windows 8.1. This update is available to all registered users.

In June 2015 I had the opportunity to teach an Advanced HemoSpat course at the Canadian Police College (CPC). We used HemoSpat version 1.8 and focused on using the new stain selection technique. This allowed me to observe its use to come up with better methods and, along with feedback from the class, used that information to fine tune the process.

HemoSpat version 1.9 introduces these refinements to make the process clearer and more streamlined.

I wrote up an article about the new stain selection workflow which should give a better idea of how it works in practice.

This release also contains many bug fixes and optimizations. For download links and a more complete list of changes, please see the release notes.

As always we look forward to hearing your feedback and suggestions!

HemoSpat version 1.8 introduced the capability to do stain selection within HemoSpat. Using reference images, the user analyzes one stain in the image and the Point Select tool allows the analysis of any other stain in the image very quickly.

This process has several benefits:

  • it speeds up the documentation process dramatically
  • it encourages the use of more stains for an analysis
  • it allows peer review of the stain selection process

In June 2015 I had the opportunity to teach a HemoSpat course at the Canadian Police College (CPC). We used HemoSpat version 1.8 and focused on using the new stain selection technique. It was clear that documenting the scene was a lot faster and that the analysts tended to use more stains in their analysis of the impact patterns. Overall it was a great validation of the process.

This was also a great opportunity for me to see the new feature in action – what worked, what didn’t, and what could be improved. I used this information along with feedback from the class in order to fine tune the process. HemoSpat version 1.9 introduces these refinements to make the process clearer and more streamlined.
