Classification of Grain Based On the Morphology, Color and Texture Information Extracted From Digital Images

Brazil is one of the largest grain producers in the world and grain classification are of great importance to the industry, since they are related to quality and economic factors. The objective of this study was to use methods of data analysis of shape, color and  texture extracted from  digital images for grain classification. From the results obtained it was demonstrated that  the  use of  patterns of  morphology, color  and  texture  extracted from images using  the  digital imaging processing techniques are effective for grain classification. The LBP texture pattern proved the most efficient information among the three, and with it alone was possible to reach a 94% hit rate. Combining addition to the pattern shape of LBP information with FCC and color with HSV was possible to improve the success rate to 96%.

USING PYTHON WITH SIMPLECV TO DETECT A CORN KERNEL IN DIGITAL IMAGE

Corn  kernels  can  have  their  nutritional  and  economic  value  hindered  by factors such as breakage and rot on the grain. The grain classification, in general, is made  by  visual  inspection  of  licensed  professionals,  and  is  a  tedious  and  tiresome process. Besides, the possibility of error is large, due to visual human subjectivity. In an attempt to reduce this subjectivity by using image processing techniques, this paper presents a computational  method  for  acquiring, preprocessing, and segmentation of corn  kernels  of  digital  images. It  is  expected  that,  with  the  proposed  program, researchers  can  have  either  their  focus  or  their  efforts  on  feature  extraction, recognition and interpretation of grains under analysis without spend time with steps related to image manipulation issues.
