This paper presents hardware and software systems which have been developed to provide haptic feedback for teleoperated laparoscopic surgical robots. Surgical instruments incorporating quantum tunnelling composite force measuring sensors have been developed and mounted on a pair of Mitsubishi PA-10 industrial robots. Feedback forces are rendered on pseudo-surgical instruments based on a pair of PHANTOM...
Text within a camera grabbed image can contain a huge amount of meta data about that scene. Such meta data can be useful for identification, indexing and retrieval purposes.Detection of colored scene text is a new challenge for all camera based images.Common problems for text extraction from camera based images are the lack of prior knowledge of any kind of text features such as color, font, size...
This paper presents an imaging technique for assessing the stimulation of H35 cells by TNF-alpha. Specifically, fluorescence from the stimulated cells is measured in order to produce intensity profiles that describe the dynamics of the NF-kappaB transcription factor. The approach offers a cost-effective, non-invasive and quantifiable alternative to traditional techniques used to acquire this intracellular...
This paper presents a solution to a general correspondence problem between a set of points (or image features) and a template, where the matching criterion includes linear parameters which reflect dynamic camera zooming during image-based tracking procedures. An algorithm is proposed which will solve this type of correspondence problem. Unlike most existing algorithms, which approach the solution...
This paper presents a robust approach based on evolutionary agents for projective reconstruction in the presence of missing data and unknown depths. Agents denote possible submatrices for rank constraints, and carry out some evolutionary behavior to exploit a vast solution space. Our approach combines the benefits of excellent searching ability of evolutionary agents for getting a good solution, with...
