A few more academic papers have been published that use Pixcavator for image analysis. An amazing variety of fields!

Google doesn’t know the difference between topology and topography, or at least definies the former via the latter. That’s just pathetic! 

I tried to illustrate the relation between Topology, Algebra, and Geometry using delicious donuts.

It may be seem strange to some that topology is related to counting but consider the fact that the key step here is to recognize that these are separate – disconnected — objects! (There are also two holes.) As you can see both computing and measuring have to rely on counting, at least initially. So, yes, topology comes first.

It’s time again to announce that the students’ applications for participation in the grant “REU Site: Computational Science Training at Marshall University for Undergraduates in the Mathematical and Physical Sciences” are being accepted. Over the summers of 2010–2012, the Departments of Mathematics, Physics, and Chemistry at Marshall University will jointly host twelve students for ten weeks of instruction and research in computational science.

The general goal is to do something new computationally while learning some math. These are the two that I supervised last summer:

• 3D image analysis by James Molchanoff
• The topology of data by Joseph Snyder, and

 

 They correspond to the first two items on this new set for 2011:

As a joint product of Intelligent Perception and AssaySoft Inc. we release Pixcavator DLL.

This library supplies the developer with a basic tool for image analysis and computer vision. The output contains the most fundamental data about the image: a list of all objects in the image along with their measurements, locations, and other characteristics. The DLL allows anyone with Microsoft Visual Studio to create new software based on the methods presented in this site. To understand the algorithms, read Grayscale Images.

This is how DLL works:

Essentially, we take care of the math for you and let you concentrate on:

• user interface,
• file management,
• data management,
• domain knowledge.

The package provides programmatic access to the low level image processing algorithms employed in our popular image analysis software. These methods have been proven in numerous applications.

This package can be used as a component in a variety of software for image analysis applications. You can think of it as a plug-in. It is a VS C# solution.

The package contains just two DLLs and a short description. Its operation is also very simple.

• The input:
  • the image,
  • the settings for size and contrast.
• The output:
  • the list of objects in the image along with their measurements and other characteristics,
  • the list of contour points for each object.
