Abstract
Certain aspects of an apparatus and method for method and apparatus for tissue region identification may include segmenting the image into a plurality of regions, filtering out regions in the plurality of regions which are curvilinear, and isolating a target area where the tissue sample is identified as the plurality of regions not filtered.
Claims20
A computer-implemented method for identifying a tissue region in a digital pathology image comprising:
- segmenting the image into a plurality of regions;
- filtering out regions in the plurality of regions to exclude from the tissue region by fitting segments in the each of the plurality of regions to a curve to determine whether the segments are curvilinear;
- and
- isolating a target area where the tissue region is identified as the plurality of regions remaining after the filtering.
An apparatus for identifying a tissue region in a digital pathology image comprising one or more processors for executing:
- a segmentation module configured for segmenting the image into a plurality of regions;
- a segment filter module configured for filtering out regions in the plurality of regions to exclude from the tissue region by fitting segments in the each of the plurality of regions to a curve to determine whether the segments are curvilinear;
- and
- a region refinement module configured for isolating a target area where the tissue region is identified as the plurality of regions not filtered out.
A computer-implemented method for identifying a tissue region in a digital pathology image comprising:
- segmenting the image into a plurality of regions;
- filtering out regions in the plurality of regions to exclude from the tissue region by:
- computing an area of a bounding box enclosing a structure in a region of the plurality of regions;
- and
- determining the structure is an artifact to exclude when a ratio of the area of the bounding box to a computed area of the region is smaller than a threshold value;
- and
- isolating a target area where the tissue region is identified as the plurality of regions remaining after the filtering.
