This work describes a cascade detection of vehicles in Unmanned Aerial Vehicle (UAV) images and videos. There are some new approaches used in the detection. In particular, the Region of Interest (ROI) search is not only based on GIS and navigation data, but also employs visual method based on rapid image segmentation and road detection. The work also suggests doing ROI segmentation by the superpixel technique and trainable four-level cascade detector that uses artificial neural networks as classifiers. Characteristics of the being analyzed regions (combined superpixels) are based on geometric and texture features, as well as on deep features extracted from the image patches by nonlinear auto encoders. To improve the detection quality of the moving vehicles a separate stage of the detector based on optical flow analysis was introduced. Proposed detection algorithm was benchmarked on the real UAV videos and showed the sufficiently high accuracy. Performance of the algorithm allows supposing the on-board usage.

This article discusses the possibility of applying the methods of allocating super pixels in the task for detecting moving and stationary vehicles in images obtained from the unmanned aerial vehicle (UAV) which flying over roads and parking lots. The paper will also consider the specificity of images obtained when shooting with the UAV, the specificity of the image processing, and formed the requirements for segmentation algorithm applicable to the task. Author of the article has developed the application required to measure the average image processing speed in the video stream and the application for evaluating vehicles partitioning quality. This application works with the test image, on which the location of the vehicle were determined by the human. A study was conducted of the several algorithms for image segmentation: LIC, Quick Shift, Felzenszwalb-Huttenlocher, and Model based clustering algorithm. The article presents data on the speed and accuracy of the evaluation of these algorithms in the task for UAV's images segmentation. In conclusion, author has chosen methods that suitable for their use in specific application task. For image segmentation, it was decided to use two of the most appropriate method: segmentation algorithm Felzenszwalb-Huttenlocher and developed by the author earlier algorithm based on the approach to clustering model based clustering. The article also discusses possible further ways of unification super pixels containing regions with vehicles. Further work will focus on the modification, parallelization and accelerate software implementation of FHS and MBC. The author will be also investigate the question of the possibility of Markov Chains to solving the task for super pixels association to the regions and the question of the applicability of the binary classification of regions for the detection of vehicles.
