Conventional radial distortion compensation methods use a calibration object or specific features within a scene. However, in this paper, we propose an automatic radial distortion compensation using a structured light system without a calibration object, a specific scene like a straight line, or knowledge of calibration parameters. When the projector illuminates straight lines along epipolar lines,...
The new Wound Diagnostics Tool (WDT) software package presented here aims to produce wound progress statistics that have clinical significance by linking digital image-based and three-dimensional (3D) geometry maps of the ulcer with existing traditional risk assessment techniques and other wound progress tracking information. All this information is then combined in a detailed electronic report that...
Speech recognition and speaker detection technique from audio visual fusion information attract much attention. In the visual side information, namely lip reading area, most of recent studies are based on analyzing shape of mouth, whereas few studies are based on analyzing lip motion. However, analysis associated with mouth motion gives essential cues for obtaining utterance mechanics. Thus, as a...
This paper introduces a non-temporal multiple silhouettes in Hidden Markov Model (HMM) for offering view independent human posture recognition. The multiple silhouettes are used to reduce the ambiguity problem of posture recognition. A simple feature extraction of the 2D shape contour based histogram is used for image encoding and K-Means algorithm is applied for clustering and code-wording of eight...
As an intelligent system, the self-tracing smart car contains a core of MCS12 micro control unit (MCU) of Freescale. Acquiring useful information provided by a CMOS camera, the system can recognize the pathway and give proper parameters, as well as choosing optimized control algorithm for image acquisition, noise filtering, shape reforming, PID or fuzzy logical control and memory methods for precise...
