The proposed method can match ink color and dye used in colorimetric reaction in terms of their absorption in spectral range (e.g., red, green, blue). A near-zero absorption channel can then be used to normalize absorption channels and construct a composite image."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Robust colorimetric processing method for paper based sensors","description":"The present disclosure proposes a colorimetric method that couples sensor design with image processing to enable automated evaluation of test results obtained by paper-based sensors.
