چکیده
In this study we test the idea of using a graphics processing unit (GPU) as an embedded co-processor for real-time speed-limit sign detection. We implement a system that operates in real-time within the computational limits of contemporary embedded general-purpose processors. The input to the system is a set of grayscale videos recorded from a camera mounted in a vehicle. We implement a new technique to realize the radial symmetry transform efficiently using rendering primitives accelerated by graphics hardware to detect the location of speed-limit sign candidates. The system reaches up to 88% detection rate and runs at 33 frames per second on video sequences with VGA (640x480) resolution on an embedded system with an Intel Atom 230 @ 1.67 GHz and a Nvidia GeForce 9200M GS.

A Template-Based Approach for Real-Time Speed-Limit-Sign Recognition on an Embedded System Using GPU Computing
We present a template-based pipeline that performs realtime speed-limit-sign recognition using an embedded system with a lowend GPU as the main processing element. Our pipeline operates in the frequency domain, and uses nonlinear composite filters and a contrastenhancing preprocessing step to improve its accuracy. Running at interactive rates, our system achieves 90% accuracy over 120 EU speed-...
متن کاملA Camera Based Speed Limit Sign Recognition System
To improve traffic safety, an automatic traffic sign detection system would be important to assist the driver. In this paper, an approach for detecting Norwegian speed limit signs is proposed. It consists of three major steps: Color-based filtering, locating sign(s) in an image and detection of numbers on the sign. About 91% correct recognition is achieved for a selection of 198 images. Ongoing...
متن کاملDetection of Norwegian Speed Limit Signs
In this paper an approach for detecting Norwegian speed limit signs is proposed. It consists of three major steps: Color-based filtering, locating sign(s) in an image and detection of numbers on the sign. Very good results are obtained for the two first steps and for the third one work is still in progress.
متن کاملJoint interpretation of on-board vision and static GPS cartography for determination of correct speed limit
We present here a first prototype of a “Speed Limit Support” Advance Driving Assistance System (ADAS) producing permanent reliable information on the current speed limit applicable to the vehicle. Such a module can be used either for information of the driver, or could even serve for automatic setting of the maximum speed of a smart Adaptive Cruise Control (ACC). Our system is based on a joint ...
متن کاملThe Speed-limit Sign Detection and Recognition System
This paper proposes a system that detects and recognizes speed-limit signs automatically. The system detects potential speed-limit sign regions by detecting maximally stable extremal regions (MSERs). The recognition is achieved by using a Support Vector Machine (SVM) classifier. The proposed system provides robustness and high accuracy in detecting and recognizing speed-limit signs when input i...
