Images distorted through defocus, motion blur, under-sampling or other reasons may be equalized. Equalized spatial frequency signals may be used to determine correspondence matching between images. Image patches from two or more image signals may be identified and analyzed to determine image patches that contain similar representations of the real scene, with sufficient local details for accurately computing cross-correlation."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Methods and systems of local signal equalization","description":"Methods and systems of equalizing spatial frequency signals for images are provided.
