Classification: CPC G | IPC G

Claim 26:
27. An apparatus for determining classifications based on whole slide images (WSIs), the apparatus comprising:
a processor;
a memory device storing software instructions for determining tissue or cell morphology classifications or regressions; and
a classification engine executable on the processor according to software instructions stored in the memory device and configured to:
obtain a test WSI;
generate a varied-size feature map for the test WSI by generating a grid of patches for the test WSI, segmenting the test WSI into tissue and non-tissue areas, and converting patches comprising the tissue areas into tensors;
generate at least one bounding box based on the patches comprising the tissue areas;
segment the at least one bounding box into feature map patches;
generate a fixed-size feature map based on at least a subset of the feature map patches; and
determine a WSI-level tissue or cell morphology classification or regression for the test WSI using a classifier model trained to process the fixed-size feature map such that a WSI-level tissue or cell morphology classification or regression is determined based on the fixed-size feature map.
