The method further includes compressing the spatial feature descriptor by determining a minimum number of bits needed to represent N, and generating a sorted array representing a ranking of the N patches based on the binary string of comparison results. Each element of the sorted array is associated with a corresponding patch of the N patches and stores a value representing a ranking of the patch relative to the other N−1 patches and coded using the minimum number of bits needed to represent N. The sorted array may be further compressed using a progressive bit representation decimation process."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Lossless spatial feature descriptor compression","description":"A computer-implemented method includes receiving a spatial feature descriptor representing a binary string of comparison results between specified pairings of N patches in a region of an image, N bein","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9799130","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.
