摘要： Computer-implemented methods and systems are provided for managing one or more images. An example method for indexing involves operating a processor to, divide an image portion of an image of the one or more images into a plurality of patches, for each patch of the image: detect one or more features of the patch; and assign the patch to at least one cluster of a plurality of clusters of the image, based on the one or more features of the patch. The processor is operable to, for each cluster of the image, select at least one patch from the cluster as at least one representative patch for the cluster; for each representative patch, generate an encoded representation based on one or more features of the representative patch; and generate an index identifier for the image based on the encoded representations of the representative patches of the image.

摘要： Various image diagnostic systems, and methods of operating thereof, are disclosed herein. Example embodiments relate to operating the image diagnostic system to identify one or more tissue types within an image patch according to a hierarchical histological taxonomy, identifying an image patch associated with normal tissue, generating a pixel-level segmented image patch for an image patch, generating an encoded image patch for an image patch of at least one tissue, searching for one or more histopathological images, and assigning an image patch to one or more pathological cases.

摘要： Computer-implemented methods and systems are provided for curating medical images for a medical image database. An example method for curating involves operating a processor to obtain a query medical image, assign the query medical image to an initial set of related images, and generate a similarity indicator for each image of the initial set. The similarity indicator is representative of a measure of similarity between image data of that image and the initial set. The processor is operable to define an intermediate set from the initial set based on the similarity indicators; and generate a relevancy indicator for each image of the intermediate set. The relevancy indicator is representative of a measure of the relevancy between relevance of the image and the intermediate set. The processor is operable to define a curated set of images from the intermediate set based on the relevancy indicators.

摘要： A computer-implemented method and system are provided for generating an encoded representation for one or more images. The method involves operating a processor to, for at least one image portion of a plurality of image portions of the image, receive a set of projection data representing an image intensity of the image portion along a plurality of projection directions; and identify a subset of projection data from the set of projection data associated with one or more dominant features. The set of projection data includes a subset of projection data for each projection direction of the plurality of projection directions. The processor is operable to generate the encoded representation based at least on a data variation within the subset of projection data for the at least one image portion.

摘要： An instrument and method for scanning all or part of a large specimen mounted on a specimen holder takes a plurality of measurements of each pixel in the whole or part of the specimen being scanned at a plurality of exposure values. A computer controls the movement of the specimen holder during scanning and again of the detector to produce a digitized image of all or part of the specimen with larger dynamic range than the dynamic range of the detection system. In a further embodiment, the instrument can scan two successive, identical strips at a different exposure values and combine the images from the two scans into one digitized image having a larger dynamic range than the dynamic range of the detection system.

摘要： An instrument and method for scanning large microscope specimen on a specimen holder has a scanning optical microscope that is configured to scan the specimen in one of brightfield and fluorescence. The specimen is dynamically tillable about a scan direction during a scan to maintain focus along the length of each scan line as the scan proceeds. A three dimensional image of the specimen can be obtained wherein the specimen tilt and relative focus are maintained from a first image contour to a second image contour through a thickness of a specimen.

摘要： A scanning microscope and method of operation has a scan filter with a repeat pattern of a plurality of rows that is repeated at least across an active area of an entire surface of an area detector. Each row is covered by a bandpass filter or an emission filter for a specific fluorophore or filters of a particular colour for each row. The scanning microscope can be used to obtain one or more of hyperspectral images, multispectral images, RGB images, RGBW images, W images and Single Field Of View images of a specimen using Moving Specimen Image Averaging. A method of obtaining one or more of the images is also described.

摘要： A mosaic scan filter array has a plurality of identical tiles, each tile have n rows and m columns where n is equal to a greater than 1 and m is equal to a greater than 2. One row of tiles extends a width of a detector array and constitutes a base pattern. The base pattern is repeated M times and each repetition is laterally offset in one direction by one pixel width. The base pattern and laterally offset repetitions constitute a repeat pattern. There are M×N filters selected from the group of one or more of the following: RGBW filters, fluorescence emission filters and a series of narrow spectral band filters covering a continuous spectral range. The mosaic scan filter arrays can be used with a scanning microscope or a scanning camera.
