摘要:
A method for realistic stitching and showing image blocks of an electronically recorded multipart image wherein relative positional offset values of the image blocks recorded with overlap are determined in a co-ordinate system in directions x and y and stored in matrix format, and the image blocks to be presented are stitched together on the basis of the stored values the method comprising: subdividing the overlaps of the individual image blocks into smaller regions with fixed relative positions; picking up at least one region most useful for the determination of the stitching; determining the offset goodness value based on the similarity of pattern of the image blocks; stitching the blocks of the image so that first the two image blocks characterized by the best offset goodness values are stitched together and the two image blocks characterized by the worst offset goodness values are stitched together last, whereas only the co-ordinates of the images figuring in a table are modified in the course of the stitching process; and distributing the errors produced by the stitching process over several image blocks.
摘要:
The present invention relates to an automated digital image recording system (1) for digitizing slides (6). The image recording system (1) comprises a slide holding means (7, 17), a mechanism for actuating it, a first digital image recording means, a second digital image recording means of high magnification and a control unit (4) for a software-based control of the automated image recording. The image recording system (1) is adapted for digitizing a slide (6) having one or more regions with sample and at least one separate region that comprises a field of information. The first digital image recording means is adapted for reading out the at least one region comprising the field of information and comprises a digital preview camera (2) capturing a low resolution preview image of each of the one or more regions with sample separately. The control unit is provided with a routine for searching points of the low resolution preview images that belong to the sample.

A slide feeding unit for a microscope includes a slide magazine having a base plate; a toothed rack secured to a magazine side wall; and slide guiding elements perpendicular to an open magazine side. The unit further includes a magazine moving mechanism having a magazine-receiving trough including opposite side plates. Two rotary shafts supported by the trough extend along the trough side plates. Magazine-advancing feeding gears are supported by the side plates and may mesh with the toothed magazine rack. Lifting gears, held in the side plates, have pins on which the magazine is supported when raised or lowered. Driving worm gears are rotated by the shafts and mesh with the lifting gears. The unit also includes a slide feeding device having a robot arm displaceable perpendicularly to the direction of advance of the magazine for removing a slide from the magazine.
