Segmenting irregular shapes in images using deep region growing with an image pyramid

摘要

A system for determining a region of interest in an image. The system includes a memory and an electronic processor. The electronic processor is configured to create an image pyramid for the image. The image pyramid includes a plurality of layers. For each layer of the image pyramid, the electronic processor is configured to initialize internal states of nodes of a spatial lattice and iteratively update the internal states of the nodes using spatially gated propagation. Each node in the spatial lattice represents a block of pixels in the image and is connected to a node representing a neighboring block of pixels in the image. The electronic processor is also configured to identify the region of interest based on the internal states of the nodes at a convergence of the spatial lattice having nodes representing values included in a first layer of the image pyramid.
