The processor specifies (i) a first corresponding point similar to a first feature point included in the reduced reference image, from the reduced comparative image, using a first filter for 3×3 pixels, and (ii) a second corresponding point similar to a second feature point in the reference image, corresponding to the first feature point, from the comparative image, using a second filter for 5×5 pixels, on the basis of a position of the first corresponding point specified in the reduced comparative image."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Image processing apparatus and image processing method","description":"A processor executes a program and reduces reference and comparative images to reduced reference and comparative images, in a ratio of ½, by setting a pixel signal value of each pixel in each image us","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9667841","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.
