The computing platform selects a plurality of seed points associated with the height field and calculates a Hessian matrix of the height field. The Hessian matrix is used by the computing platform to trace (a) one or more ridge curves associated with the height field and (b) one or more valley curves associated with the height field using the plurality of seed points."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Robust automatic computation of ridges and valleys of a height field","description":"A computer-implemented method for computing ridges and valleys of a height field includes a computing platform receiving a plurality of sample points associated with a dataset and an indication of an ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9754180","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
