2DTG unveils upgrade to its Data Matrix Decoding Library – Release 18.01

Mon, 2018-01-22

This release represents major algorithmic improvement for our Data Matrix decoding library providing an increase in the success decode rate by about 30% (as measured by the numbers of undecoded images in our sample set of almost 3,000 Data Matrixes).  

This improvement includes:

  1. Algorithm enhancement to accommodate greater distortions of Data Matrices having damaged L-shape and/or Clock Pattern or DM symbols printed on curved surfaces
  2. New Decode Mode - Ultimate+ -  designed to improve decoding of samples that feature highly uneven illumination pattern. 

Though this “Ultimate+” algorithm is more time-consuming, it is very effective, particularly, on some “low quality” images, as follows:
