Shape analysis of common bean (Phaseolus vulgaris L.) seeds using image analysis

Abstract:Morphological features of common bean (Phaseolus vulgaris L.) seeds were measured in five bean cultivars (Akhtar, Ks21189, Ks31169, G11867 and khomein) using digital image analysis. The images of seeds were captured using digital camera (Canon G7). The images were analyzed using image processing toolbox of MATLAB ver. 7.6 software. Morphological features including Area, Perimeter, Major and Minor Axis Length, Eccentricity, Convex Area, Extent, Compactness, Aspectratio, Feret Diameter, Roundness and Elongation were extracted on binary image. The bean cultivars which used in this study showed significant difference in all features. It was concluded that morphological features are powerful tool which could separates the seed cultivars. More numerical results described in the paper.
