Vehicle Counting in Still Image
Vágner, Filip ; Juránek, Roman (referee) ; Špaňhel, Jakub (advisor)
The goal of this work is to compare models of convolutional neural networks designed to count vehicles in a static image using density estimation with a focus on different sizes of objects in the scene. A total of four models were evaluated - Scale Pyramid Network, Scale-adaptive CNN, Multi-scale fusion network and CASA-Crowd. The evaluation was done on three data sets - TRANCOS, CARPK, PUCPR+. Scale Pyramid Network achieved the best results. The model reached 5.44 in the Mean Absolute Error metric and 9.95 in the GAME(3) metric on TRANCOS dataset.

Vehicle Counting in Still Image
Jelínek, Zdeněk ; Juránek, Roman (referee) ; Špaňhel, Jakub (advisor)
The main goal of this thesis was to compare different approaches to vehicle counting by density estimation. Four convolutional neural networks were tested - Counting CNN, Hydra CNN, Perspective-Aware CNN and Multi-column CNN. The evaluation of these models was done on three different datasets. The Perspective-aware CNN has achieved the most accurate results across all datasets. This model has reached 2.86 Mean Absolute Error on the PUCPR+ dataset, proving that it is the most suitable for the vehicle counting problem.

Counting Vehicles in Image and Video
Gabzdyl, Dominik ; Herout, Adam (referee) ; Špaňhel, Jakub (advisor)
Analýza silničního provozu je stále náročnou úlohou. V průběhu této úlohy se vyskytují mnohá úskalí, která je třeba brát na vědomí. Například malé rozlišení obrazu, vysoký počet překrývajících se objektů, úhel kamery, rozmazání objektů v důsledku jejich pohybu nebo povětrnostní podmínky. Tato práce adresuje tato úskalí použitím konvolučních neuronových sítí. V této práci představuji novou architektu založenou na principu počítání regresí (Counting by Regression). Navržená architektura je inspirována některými state-of-the-art architekturami a vylepšuje přesnost na různých datasetech. Například na velmi malém PUCPR+ datasetu byla odmocnina ze střední kvadratické chyby (RMSE) snížena z 34.46 na 6.99 vozidel (měřeno na test setu). Dosažené výsledky ukázaly, že je zde stále prostor ke zlepšení a možný další výzkum v oblasti počítání regresí.

Vehicle Counting in Still Image
Hladiš, Martin ; Juránek, Roman (referee) ; Špaňhel, Jakub (advisor)
The goal of this thesis is to compare different models of convolutional neural networks, which use the principle of using density estimation to count the number of vehicles in a still image. The tested models were -- Counting CNN, Scale-adaptive CNN, Multi-Scale Fusion Net a Multi-scale CNN. Their estimation capability was tested using these datasets -- TRANCOS, CARPK, PUCPR+. The most accurate results were achieved by the Multi-Scale Fusion Net model. Its estimation accuracy using the dataset TRANCOS in the Mean Absolute Error metric achieved value of 8.05.

Vehicle detection in images
Pálka, Zbyněk ; Přinosil, Jiří (referee) ; Krajsa, Ondřej (advisor)
This thesis dissert on traffic monitoring. There are couple of different methods of background extraction and four methods vehicle detection described here. Furthermore there is one method that describes vehicle counting. All of these methods was realized in Matlab where was created graphical user interface. One whole chapter is dedicated to process of practical realization. All methods are compared by set of testing videos. These videos are resulting in statistics which diagnoses about efficiency of single one method.
