Abstract
The present disclosure relates to systems, non-transitory computer-readable media, and methods for extracting and tracing ridges at junctions, including confluences, corners, and terminals. For example, the disclosed systems generate, from a digital image, a pixel ridge using a distance transform and a depth-first traversal of pixels in the digital image. In some embodiments, the disclosed systems determine a junction within the pixel ridge by segmenting the pixel ridge into logical branches. In certain embodiments, the disclosed systems classify the junction as a confluence based on determining that the junction is made up of at least a threshold number of incident branches within the pixel ridge. In some embodiments, the disclosed systems reconstruct the confluence by detecting a region of deformity for the confluence and replacing pixels in the region of deformity with extrapolated pixels connecting incident branches.
