Resumo
Insects cause significant losses of stored grains in both quantity and quality. In the scenary,
it is of paramount importance an early identification of insects in grains to take control measures.
Instead of sampling and visual/laboratory analysis of grains, we propose to carry
out the insects identification task automatically, using computational methods to perform
endoscopic video analysis. The videos are recorded inside of grains warehouses by an endoscopic
camera. As the classification process of moving objects in video rely heavily on precise
segmentation of moving objets, we propose a new method of background subtraction and
compared their results with the main methods of the literature according to a recent review.
The main innovation of the background subtractionmethod rely on the binarization process
that uses two thresholds: a global and a local threshold. The binarized results are combined
by adding details of the object obtained by the local threshold in the result of the global threshold.
Experimental results performed through visual analysis of the segmentation results
and using a SVM classifier, suggest that the proposed segmentation method produces more
accurate results than the state-of-art background subtraction methods.
