摘要

An image analysis system for analyzing biological specimen images is disclosed. The system may include: a superpixel generator configured to obtain a biological specimen image and group pixels of the biological specimen image into a plurality of superpixels; a feature extractor configured to extract, from each superpixel in the plurality of superpixels, a feature vector comprising a plurality of image features; a clustering engine configured to assign the plurality of superpixels to a predefined number of clusters, each cluster being characterized by a centroid vector of feature vectors of superpixels assigned to the cluster; and a storage interface configured to store, for each superpixel in the plurality of superpixels, clustering information identifying the one cluster to which the superpixel is assigned. The system may also include a graph engine configured construct a graph based on the stored information, and use the graph to perform a graph-based image processing task.

說明書

FIG. 6 illustrates an example computing device 600, in according to some embodiments. Computing system 600 may correspond, for example, to system analysis 100, to a portion thereof, or to any other computing system suitable for performing the functionality described below. Computing system 600 may include a processing resource 610, which, as discussed above, may correspond to processor 117 or to any other processing resource suitable for performing the functionality described below. Computing system 600 may also include a non-transitory computer-readable storage medium 620, which, as discussed above, may correspond to memory 116 or to any other non-transitory computer-readable storage medium capable of storing instructions executable by processing resource 610.

In the particular example shown in FIG. 6, medium 620 may store instructions 622, 624, 626, 628, 630, 632, and any other instructions that can be fetched, decoded, and executed by processing resource 610. Instead of or in addition to retrieving, decoding, and executing instructions, processing resource 610 may include any number of electronic circuits comprising any number of electronic components for performing the functionality of any number of instructions in machine-readable storage medium 620. With respect to the executable instruction representations (e.g., boxes) described and shown herein, it should be understood that part or all of the executable instructions and/or electronic circuits included within one box may, in other examples, be included in a different box shown in the figures or in a different box not shown.
