Advanced driver assistance systems (ADAS) are designed to increase driver's situational awareness and road safety by providing essential information, warning and automatic intervention to reduce the possibility/severity of an accident. Of the various types of ADAS modalities available, camera based ADAS are being widely adopted for their usefulness in varied applications, overall reliability and adaptability...
In computer vision, the Harris corner feature detector is one of the most essential early steps in many useful applications such as 3-D reconstruction. However, if it is implemented in software, the resulting code is probably not able to be executed in real time under low cost mobile processors. This paper proposes an efficient hardware approach that offloads the repetitive feature extraction procedures...

This paper presents a system for real-time calibration of moving and zooming video cameras. In order to satisfy the real-time constraints, the calibration of each video frame has to be computed before the acquisition of the next frame is completed (40 milliseconds for PAL standard). Because of such time requirements, the proposed system is based on a multi-DSP processor architecture: the digitized...
