Title: SYSTEM AND METHOD FOR MEASURING IMAGE RESOLUTION VALUE
Abstract:
A system and method for measuring an image resolution value. The method for measuring an image resolution value comprises: convoluting an image by using an image feature extractor, to extract a first feature image from a part of the image (240); down-sampling, by using the image feature extractor, the first feature image obtained by convolution to obtain a second feature image with low resolution (250); performing column transformation on the down-sampled second feature image by using the image feature extractor, to obtain a single-column feature vector (260); and performing resolution value calculation on the single-column feature vector by using a predicator, to obtain a resolution value of the image (270). The method can measure a resolution value of an image quickly, is easy in training, uses few parameters, and can measure the resolution value accurately in real time. The method is widely applicable to an optical imaging system and a medical imaging system.
