Real time 3d surface feature extraction on fpga
Tellioğlu, Zafer Haşim; Ulusoy, İlkay; Department of Electrical and Electronics Engineering (2010)
Three dimensional (3D) surface feature extractions based on mean (H) and Gaussian (K) curvature analysis of range maps, also known as depth maps, is an important tool for machine vision applications such as object detection, registration and recognition. Mean and Gaussian curvature calculation algorithms have already been implemented and examined as software. In this thesis, hardware based digital curvature processors are designed. Two types of real time surface feature extraction and classification hardwar...
Real time traffic sign recognition system on FPGA
Irmak, Hasan; Bulut, Mehmet Mete; Akar, Gözde; Department of Electrical and Electronics Engineering (2010)
In this thesis, a new algorithm is proposed for the recognition of triangular, circular and rectangular traffic signs and it is implemented on an FPGA platform. The system can recognize 32 different traffic signs with high recognition accuracy. In the proposed method, first the image is segmented into red and blue regions, and according to the area of the each segment, the dominant color is decided. Then, Laplacian of Gaussian (LoG) based edge detection is applied to the segmented image which is followed by...

Real time FPGA implementation of Full Search video stabilization method
ÖZSARAÇ, ismail; Ulusoy, İlkay (2012-04-20)
Full Search video stabilization method is implemented on FPGA to realize its real time performance. Also, the method is implemented and tested in MATLAB. FPGA results are compared with MATLAB's to see the accuracy performance. The input video is PAL which frame period is 40 ms. The FPGA implementation is capable of producing new stabilization data at every PAL frame which allows the implementation to be classified as real time. Simulation and hardware tests show that FPGA implementation can reach the MATLAB...
Real Time FPGA Implementation of Super Resolution for Infrared Cameras
AKTUKMAK, Mehmet; Halıcı, Uğur (2015-08-24)
At present, the quality of image taken from infrared cameras is low compared to the other cameras because of manufacturing technology. Therefore, resolution enhancement processes are becoming more important for these cameras. Super resolution is a good approach to solve this resolution problem. In general, the systems that infrared cameras used require video processing to perform in real time. So, a suitable approach should be selected and implemented to work in real time. The computational load and process...
