We introduce a new mono-camera system with multi-infrared lights for human posture recognition, which is based on the 3D body shape recovered from the body silhouette and cast shadows. We propose a new voxelization method inspired from the Shape From Silhouettes (SFS) approach for Visual Hull (VH) reconstruction. Our setup consists of 4 infrared lights installed in the different upper corners of a...
Recognition of banknotes is a prevalent problem for blind and visually impaired people. The bionic eyeglass is a mobile platform that integrates several common visual detection and recognition functions. Relevant shapes are extracted from the image flow of the banknote shown to the mobile camera using adaptive thresholding and morphological shape filters. In a two-level classification scheme different...
We present a novel system for automatic identification of vehicles as part of an intelligent access control system for a garage entrance. Using a camera in the door, cars are detected and matched to the database of authenticated cars. Once a car is detected, License Plate Recognition (LPR) is applied using character detection and recognition. The found license plate number is matched with the database...
We review some recent techniques for 3D tracking and occlusion handling for computer vision-based augmented reality. We discuss what their limits for real applications are, and why object recognition techniques are certainly the key to further improvements.
