Detection and Classification of Road Users in Aerial Imagery Based on Deep Neural Networks
Hlavoň, David ; Hradiš, Michal (referee) ; Rozman, Jaroslav (advisor)
This master's thesis deals with a vehicle detector based on the convolutional neural network and scene captured by drone. Dataset is described at the beginning, because the main aim of this thesis is to create practicly usable detector. Architectures of the forward neural networks which detector was created from are described in the next chapter. Techniques for building a detector based on the naive methods and current the most successful meta architectures follow the neural network architectures. An implementation of the detector is described in the second part of this thesis. The final detector was built on meta architecture Faster R-CNN and PVA neural network on which the detector achieved score over 90 % and 45 full HD frames per seconds.

Deep Learning for 3D Image Analysis
Hlavoň, David ; Herout, Adam (referee) ; Španěl, Michal (advisor)
This work deals with usage of fully convolutional neural network for segmentation of bones in CT scans. Typical issue is limited size of dataset while training on medical images. Experiments show that training on patches gives score of segmentation 95,1%. Training on whole images gives score 30% less than training on patches. As metric F-measure was used. BVLC Caffe Framework was used for training neural network.
