In the paper, an attempt towards morphological analysis implementation into grain physical features extraction, with the use of APR software, has been presented. The main objective of the research is to determine the physical characteristics of wheat grains in order to assess the automatic grain quality review. Photographic macro images of wheat grains were taken for the purpose of this study, and then they were processed using the APR application. Properly prepared graphic material has been subjected to segmentation and morphological analysis. Parameters derived from morphological analysis are presented synthetically and form the basis for further research focused on statistical analysis.
