ANALYSIS OF BLUR AND NOISE INFLUENCE ON DIGITAL IMAGE QUALITY
Annotation
The combined method of evaluation of digital image contrast and sharpness is proposed. Analysis of blur and noise influence on digital image quality is carried out. The dependences of image contrast and sharpness on defocusing under different levels of noise are calculated. The joint consideration of contrast and sharpness for digital image quality evaluation is found to be important precondition.
