  • Patent number: 12079958
    Abstract: The method is used for creating an all-in-focus image of a portion of an iridocorneal angle of an eye starting from a plurality of images (610), these images being shallow field-depth images of that portion taken with different focus planes but with a same image frame; the method comprises the steps of: A) pre-processing (620) said plurality of images so to obtain a plurality of single-channel images if the images of said plurality are color images, B) calculating (630) an initial focus map starting from said plurality of single-channel images, C) creating (640) an initial estimated all-in-focus image starting from said initial focus map and said plurality of single-channel images, D) calculating (650) an initial edge map starting from said initial focus map and said plurality of single-channel images, E) iterating (660) a regularization process until a stop regularization condition is met, wherein the regularization process comprises removing one or more edge points of the initial edge map by considering a r

  • Publication number: 20190150726
    Abstract: The method of creating and processing a color image of an iridocorneal region of an eye includes the preliminary step of calibrating a pair of a color image detector device and a color illuminator device; and the examination steps of: detecting the color image through the detector device including a bi-dimensional array of pixels, wherein the color image is in a color space defined by three color dimensions, selecting a sub-image within the detected image corresponding to a region of interest, computing a statistic parameter of the selected sub-image, wherein the statistic parameter is selected from the group including an average value, a variance value, a minimum value, a maximum value, a skewness value, a kurtosis index value, a distribution, and a distribution gradient of a color component, determining an indicator based on the statistic parameter through a statistical classifier, and providing the indicator as an examination result.

  • Patent number: 9380939
    Abstract: A fundus photographing apparatus includes: a photographing unit including a fundus illumination optical system to illuminate a fundus of a patient's eye and a fundus photographing optical system having a light receiving element to obtain a fundus image of the illuminated eye; and an alignment unit to position the photographing unit with the eye based on a predetermined alignment reference position. The alignment unit includes: an extracting part to extract, by image processing, an image region formed by reflection light from a portion other than the fundus from the fundus image obtained by the fundus photographing optical system; a gravity center calculating part to determine, by arithmetic processing, a gravity center position of the extracted image region; and a control part to perform alignment control of the photographing unit with the eye based on the calculated gravity center position and the alignment reference position.
