Abstract
Systems, methods and computer readable media for exposure quality detection are described. In some implementations, a method can include computing an overall image exposure score for an image. The method can also include determining one or more face regions in the image. The method can further include computing a face region exposure score for each face region. The method can also include combining the overall image exposure score and each face region exposure score to generate an exposure quality score for the image.
Claims17
A method comprising:
- computing an overall image exposure score for an image, the overall exposure score being based on a clipped pixel score and a tonal distribution score;
- determining one or more face regions in the image;
- computing a face region exposure score for each face region, the face region exposure score including a clipped pixel score and a face region tonal distribution score;
- adjusting the overall image exposure score and each face region exposure score according to a penalty value;
- combining the overall image exposure score and each face region exposure score to generate an exposure quality score for the image;
- and
- applying one or more of an overall exposure correction and an independent correction for each face region.
A method comprising:
- computing an overall image exposure score for an image;
- determining one or more face regions in the image;
- computing a face region exposure score for each face region;
- and
- combining the overall image exposure score and each face region exposure score to generate an exposure quality score for the image.
A system comprising one or more computers configured to perform operations including:
- computing an overall image exposure score for an image;
- determining one or more face regions in the image;
- computing a face region exposure score for each face region;
- and
- combining the overall image exposure score and each face region exposure score to generate an exposure quality score for the image.
