Map-Based Microscope Positioning
نویسندگان
چکیده
In microscopy, regions of interest are usually much smaller than the whole slide area. Various microscopy related medical applications are liable to benefit greatly from microscope auto positioning in previously defined regions of interest. In this paper we present a method for image-based auto positioning on a microscope slide. The method is based on localization of a microscopic query image using a previously acquired slide map. It uses geometric hashing, a highly efficient technique drawn from the object recognition field. The algorithm exhibits high tolerance to possible variations in visual appearance due to slide rotations, scaling and illumination changes. Experimental results indicate high reliability of the algorithm.

متن کاملAutomatic Positioning of a Surgical Microscope
A procedure for interactive navigation of a fully motorized surgical microscope is presented. This procedure uses preoperative MRTor CT-images to generate a 3D-model of the patient which then acts as the basis for navigation during surgery. The relation between tracking system, microscope and 3D-model is established using a simple calibration method based on the Horn [Ho87] algorithm. It enable...
متن کاملA simultaneous localization and tracking method for a worm tracking system
The idea of worm tracking refers to the path analysis of Caenorhabditis elegans nematodes and is an important tool in neurobiology which helps to describe their behavior. Knowledge about nematode behavior can be applied as a model to study the physiological addiction process or other nervous system processes in animals and humans. Tracking is performed by using a special manipulator positioning...
