Dmytro Kyrychuk, Andriy Segin · 2021
This paper presents peculiarities of dataset preparation for convolutional neural network training and specificities, which influence the further object recognition by trained network. The influence of illumination and contrast of images from dataset on quality of network training was researched. Rationality of using neural network transfer learning for increasing accuracy of recognition was demonstrated. The object recognition ability of a convolutional neural network while scaling the object or changing objects’ appearance relatively to initial images from training dataset was researched. The results of influence of illumination on quality of object recognition by trained network and influence of background on the quality of feature selection were presented.
