Real-Time Lane Detection and Rear-End Collision Warning System On A Mobile Computing Platform

Accident prevention systems have recently been a part of many modern cars to reduce injuries and casualties on the road. However, the high cost of components and equipment have limited such accident prevention systems to mostly available in higher-end and luxury vehicles. Therefore, an economical method of using a smartphone application for real-time lane detection and rear-end collision warning system for drivers on the road is crucial so that a wider class of road users can benefit from such safety system. The Android-based application uses image-processing algorithms coupled with the monoscopic camera on the smartphone as the main sensor to perform lane and vehicle detection. The novelty of this work lies in the use of the monocular vision of the camera to estimate the distance with the vehicle up ahead. The system is able to distinguish unintentional lane departure or if the driver is traveling too close to the vehicle in front, where an acoustic warning system is used to notify the driver of a potential accident.

Visiting Lectures: Parallel Coordinates in Computer Vision and Object Detection with WaldBoost

Dr. Dubska and Dr. Juranek from Brno University of Technology introducing their research

Dr. Marketa Dubska and Dr. Roman Juranek from Brno University of Technology (BUT) from Czech Republic will give presentations about

Parallel Coordinates in Computer Vision and
Object Detection with WaldBoost

Wednesday September 24, 2014 at 14:30-16:00 in Room 2411 (seminar room at MVPR).

See the abstracts below.

Welcome!

Prof. Heikki Kälviäinen

Dr. Marketa Dubska: Parallel Coordinates in Computer Vision

The presentation focuses on usage of parallel coordinates in computer vision. The parallel coordinate system represents the space with axes which are mutually parallel. It can be used as a parameterization of lines and points for the Hough transform which requires only rasterization of lines, therefore it is very fast and accurate. The method is demonstrated on the matrix code extraction and the detection of vanishing points in Manhattan world images or roadside data.

Dr. Roman Juranek: Object Detection with WaldBoost

In my talk, I will briefly introduce WaldBoost algorithm for training object detectors (e.g. detection of faces in images). And I will summarize our research on acceleration of the detection process on various architectures (CUDA, FPGA). Finally, I will introduce our current research on multiview object detection with randomized forests, and its applications to traffic surveillance - detection of cars on highways.

Video Processing, Action and Object Detection

The talk addresses video processing algorithms with focus on action detection, object detection, and shortly also mentions other techniques, such as high dynamic range processing. Action detection, from the point of view of this talk is based on processing of video sequences using space-time features run though visual vocabulary, converted into BOW and classified using SVM. The main point of research is not improvement of the detection itself, although the solution is a state of the art one, but rather investigation of how the size of the video sequence being processed affects the detection rate and whether an optimal length exists and how it is dependent on the individual actions to be detected. Object detection in images is one of the key algorithms of computer vision. The talk will also address recent advances in object detection at FIT and its implementation in programmable hardware, specifically in FPGA. The implementation of WaldBoost, LBP and LRD feature extraction, memory layout, and prediction of neighborhood results will be given. HDR image acquisition from multiple exposure cameras and HDR image encoding present important problems in image acquisition. As for the HDR, current advances in HDR acquisition and encoding will be briefly presented as well as a possibility of exploitation of HDR in the above algorithms. Performance and results will be discussed as well and a future work outlined. Additionally, some brief information about current direction of research at FIT in object detection, HDR image acquisition, and other relevant direction.

Human Vision and Computer Graphics

Human visual system is a complex and sophisticated network. It adapts to different object distance, luminance level, illumination hue, contrast or detail level. Our sight can deal with rapid light changes, immense contrasts or very dim light. On the other hand, some of the mechanisms are sources of optical illusions. Modern computer graphics is often inspired by human vision. Local contrast, global illumination or hue perception are perceived differently to the artificial image capture. Understanding of our vision helps to capture, process and reconstruct images more reliably.
