In this paper, the observation technique on the miCTO environments with a real-time virtual reality camera system, whitch is constructed with a dynamic focusing lens and a smart vision sensor using the “depth from focus” criteria, has been discussed In the operation with a microscope, such as the micro-surgery, DNA operation and etc., the small depth of a focus makes bad controllability to actu...
A novel robust digital image watermarking scheme based on singular value decomposition (SVD) and micro-genetic algorithm (micro-GA) is proposed in this paper. In an SVD-based watermarking scheme, the singular values of the cover image are modified to by considering multiple scaling factors to embed the watermark image. Determining the proper values of scaling factors is not an easy task. Here w...
Active Q control may be used to modify the effective quality (Q) factor of an atomic force microscope (AFM) micro-cantilever when operating in tapping mode. The control system uses velocity feedback to obtain an effective cantilever Q factor to achieve optimal scan speed and image resolution for the imaging environment and sample type. Time delay of the cantilever displacement signal is the mos...
In this Paper a micro display for an intraocular vision aid (IOVA) projecting an image of the environment onto the retina is presented. The display comprises an image of an array made out of single LED pixels. It is connected to a CMOS driver circuit using flip-chip technique. Since micro lenses have to be integrated into the substrate material for proper image projection onto the retina the ge...
