  • Method of detecting and quantifying blur in a digital image
    Patent number: 9076192
    Abstract: Method of detecting and quantifying blur in a digital image implementing a computer and comprising: —a step a) of obtaining a digital image; a step b) of obtaining a brightness parameter for each pixel on the basis of the digital image, the step b) comprising an operation of convolution with an edge detection matrix; a step c) of calculation of a score S1 comprising the maximum, calculated over all the pixels, of the brightness parameter obtained in step b); and a step d) a step of evaluating the digital image, the digital image being considered to be blurred if the score S1 obtained in step c) is strictly less than a first predetermined threshold, the score S1 providing a first quantity of blur present in the digital image.
