20090060303 | METHOD AND APPARATUS FOR AUTOMATED IMAGE ANALYSIS OF BIOLOGICAL SPECIMENS - A method including acquiring images of medical slides at a plurality of different focus positions, determining a position which produces a maximum value of pixel values relative to a pixel value mean, wherein said determining comprises using a pixel value mean as a coarse estimate of coarse focus position, and subsequently refining said coarse focus position to find a fine focus position, and wherein said refining comprises fitting to a polynomial, and using a specified portion of the polynomial as a fine estimate of focus position, and producing a focus control signal that is related to said maximum value to control a focus position. | 03-05-2009 |
20080260233 | AUTOMATED METHOD FOR IMAGE ANALYSIS OF RESIDUAL PROTEIN - A method for measuring residual protein in a cellular specimen including obtaining a low magnification image of a candidate object of interest, filtering the candidate object of interest pixels with a low pass filter, morphologically processing the candidate object of interest pixels to identify artifact pixels, identifying the candidate object of interest by eliminating artifact pixels, acquiring a higher magnification image of the subsample for the candidate object of interest, transforming pixels of the higher magnification image in a first color space to a second color space to differentiate higher magnification candidate object of interest pixels from background pixels, identifying an object of interest from the candidate object of interest pixels in the second color space, and determining the optical density of the protein in a cell contained in a subsample, wherein the optical density is indicative of the residual component of a cellular protein. | 10-23-2008 |
20080258061 | METHOD AND APPARATUS FOR AUTOMATED IMAGE ANALYSIS OF BIOLOGICAL SPECIMENS - An electronic microscope system including a processor, a movable stage movable in two orthogonal directions under control of the processor, the movable stage including at least one part that determines a current position of the movable stage, a microscope part, which magnifies a sample on the movable stage, an electronic camera part, which obtains an image of a magnified sample at a specified position controlled by the movable stage, and at least one vibration isolation mount, coupled to the stage and isolating vibration between the movable stage and the microscope part. | 10-23-2008 |
