The method further calculates a sharpness threshold as a function of the filtered pixel values. In addition, the method calculates a sharpness weight for each filtered pixel value as a function of the filtered pixel value and the sharpness threshold. The method calculates a weighted pixel value for each filtered pixel value as a function of the filtered pixel value and the corresponding sharpness weight for the filtered pixel value. The method further calculates a sharpness value for the image as a function of the weighted pixel values."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Calculating a sharpness value","description":"For calculating a sharpness value, a method filters an image with an edge extraction filter to generate filtered pixel values for each pixel of the image.
