Caliper Software for Milled-Rice – Counts the number of grains, headrice and broken kernels September 14, 2008

Milled rice software caliper This is an application for counting milled rice grains, determining the count of headrice, broken, and brewers. Using these grade factors, the caliper software (as I call it) is able to estimate the total weight in terms of percentage. Weight estimation of rice grain is performed using linear regression and support vector machines (SVM). It uses AForge library from AForge.NET for various image processing task.

I did this software for Bureau of Post-harvest Research Extension (BPRE) and indirectly, to National Food Authority (NFA) for the purpose of quickly determining the grain size of milled rice.

The demo and initial version of the caliper software is available for download here:

To use the software, simply install the application, then open the sample image included in the installation (“bigas.bmp”), then that’s it!  You can try it for other similar problems, like corn, barley, etc.  Please give me feedback if problems arises.  For any questions, you may email me at {vlad_crasher at yahoo point com}.

UPDATE: Yesterday (September 15, 2008), they told me that the test was successful!  The classification result did matched with the manual methods performed by human inspector.

Few months ago, I completed a utility capable of measuring the percentage by weight of headrice, broken kernels and brewers for .  A screen shot is shown below.

The software is used for determining the grain size of a given milled rice sample.  Additional information about other milled rice grade factors are also provided as follows:

  1. Total number of kernels and weight of the milled rice sample
  2. Number of headrice and weight
  3. Number of broken kernels including its total weight
  4. Brewers

I will provide more information soon.  Keep posted!  And hey… feel free to comment.  Tell me what you think!
