SYSTEMS AND METHODS FOR GENERATING ENCODED REPRESENTATIONS FOR MULTIPLE MAGNIFICATIONS OF IMAGE DATA
Publication number: 20230343081Abstract: Computer-implemented methods and systems are provided for generating encoded representations for multiple magnifications of one or more query images. An example method for involves operating a processor to obtain a query image and identify a set of anchor points within the query image. The processor is operable to generate a plurality of sub-images for a plurality of magnification levels for each anchor point. Each sub-image includes the anchor point and corresponds to a magnification level of the plurality of magnification levels. The processor is operable to, for each magnification level, apply an artificial neural network model to a group of sub-images having that magnification level to extract a feature vector representative of image characteristics of the query image at that magnification level; and to generate an encoded representation for multiple magnifications of the query image based on the feature vectors extracted for the plurality of magnification levels.Type: ApplicationFiled: February 16, 2023Publication date: October 26, 2023Inventors: Hamid Reza Tizhoosh, Savvas Damaskinos, Arthur Edward Dixon -
Publication number: 20230335260Abstract: Various image diagnostic systems, and methods of operating thereof, are disclosed herein.

Patent number: 11769582Abstract: 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.Type: GrantFiled: November 5, 2019Date of Patent: September 26, 2023Assignee: HURON TECHNOLOGIES INTERNATIONAL INC.Inventors: Hamid Reza Tizhoosh, Wafik Wagdy Moussa, Savvas Damaskinos, Patrick Myles, Alfonso Carlos Ribes

Publication number: 20230230709Abstract: 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.Type: ApplicationFiled: February 17, 2023Publication date: July 20, 2023Inventors: Hamid Reza Tizhoosh, Patrick Myles, Savvas Damaskinos
