Abstract
The present disclosure discusses systems and methods to detect blur in digital images. The solution can be incorporated into the quality control systems of pathology and other slide scanners or can be a stand-alone solution. The solution can identify scanned images that include blur and cause the scanner to automatically rescan the blurry image. The solution can also identify regions of the scanned image that include blur. The solution can generate blur maps for each of the scanned images that identify regions of the scanned image that include blur.
Claims20
A system to prepare histological slides, comprising one or more processors to:
- a patch generator executed by the one or more processors to generate a plurality of patches from a digital image, each patch of the plurality of patches comprising a plurality of pixels;
- a feature extractor to calculate, for each patch of the plurality of patches, values according to one or more sharpness metrics;
- and
- a patch classifier to:
- determine a blur score for each patch of the plurality of patches, the blur score of the patch determined using the calculated values of the one or more sharpness metrics of the patch;
- and
- generate a blur map based on the blur score for each patch of the plurality of patches, the blur map including, for each patch of the plurality of patches, a parameter value between a first threshold value and a second threshold value that is based on the blur score of the patch.
A method for detecting a quantity of blur in images, comprising:
- generating, by a blur detector including one or more processors, a plurality of patches from a digital image, each patch of the plurality of patches comprising a plurality of pixels;
- calculating, by the blur detector, for each patch of the plurality of patches, values according to one or more sharpness metrics;
- determining, by the blur detector, a blur score for each patch of the plurality of patches, the blur score of the patch determined using the calculated values of the one or more sharpness metrics of the patch;
- and
- generating, by the blur detector, a blur map based on the blur score for each patch of the plurality of patches, the blur map including, for each patch of the plurality of patches, a parameter value between a first threshold value and a second threshold value that is based on the blur score of the patch.
