Abstract

Methods, media, and systems for assessing the quality of a digital image. In an embodiment, both a micro-analysis and macro-analysis are performed. The micro-analysis comprises dividing the digital image into a plurality of blocks, for two or more of the plurality of blocks, determining a score based on a spatial frequency of the block, and generating a score map for the digital image based on the score for each of the two or more blocks. The macro-analysis comprises detecting artifacts in the digital image, computing a degradation score based on detected artifacts, and computing a whole-slide-quality score based on the score map and the degradation score.

First claim

What is claimed is:

1. A method for assessing a quality of a digital image, the method comprising using at least one hardware processor to:
perform a micro-analysis comprising
dividing a digital image into a plurality of blocks,
for two or more of the plurality of blocks, determining a score based on a spatial frequency of the block, and
generating a score map for the digital image based on the score for each of the two or more blocks; and

perform a macro-analysis compris…
