This paper expounds the working principle of pharmacy robot vision system combining with the mechanical structure of the pharmacy robot. Firstly, the visual system takes the digital images of ampoules and penicillin bottles by the CCD camera. Secondly, we use the functions of OpenCV to extract the ROI of bottle image, filter, segment, and extract the characteristic parameters such as diameter, height,...
Finding reliable corresponding points between two images of a scene is a fundamental problem in computer vision. In this paper, a hybrid scheme is proposed, which combines invariant spatial feature and frequency domain based methods in a hierarchical multi-scale way. The Fourier-Mellin Transform is applied to obtain the transformation parameters at the coarse level between the two images; then, the...
We present an agent-based full body tracking and 3D animation system to generate motion data using stereo calibrated cameras. The novelty of our approach is that agents are bound to body-part (bone structure) being tracked. These agents are autonomous, self-aware entities that are capable of communicating with other agents to perform tracking within agent coalitions. Each agent seeks for ldquoevidencerdquo...
Wall-pasted cell segmentation plays an important role in ectogenetic anti-virus experiment. Traditional Gabor filter (TGF) has been introduced to enhance the cell boundaries, which resulted in a reasonable segmentation. However, the boundaries are of arbitrary orientations, which make the orientation selectivity of TGFs become a computational burden, because Gabor filters of six or more orientations...
