Abstract
Techniques related to no-reference image and video quality evaluation are discussed. Such techniques may include generating, for a still image or video frame, features including a natural scene statistics based feature and an image quality based feature and determining an image evaluation indicator associated with the still image or video frame based on a mapping of the generated features to the image evaluation indicator.
Claims25
A method for performing no-reference image or video evaluation comprising:
- determining a candidate image is a valid image for quality evaluation based at least in part on a composition check of the candidate image or a category check of the candidate image;
- generating features associated with the valid image, wherein the features comprise at least one natural scene statistics based feature and at least one image quality based feature;
- and
- determining an image evaluation indicator associated with the valid image based on a mapping of the generated features to the image evaluation indicator.
A system for performing no-reference image or video evaluation comprising:
- a memory configured to receive a valid image for quality evaluation;
- and
- a central processor coupled to the memory, the central processor to determine a candidate image is a valid image for quality evaluation based at least in part on a composition check of the candidate image or a category check of the candidate image, to generate features associated with the valid image, wherein the features comprise at least one natural scene statistics based feature and at least one image quality based feature, and to determine an image evaluation indicator associated with the valid image based on a mapping of the generated features to the image evaluation indicator.
At least one machine readable medium comprising a plurality of instructions that, in response to being executed on a device, cause the device to perform no-reference image or video evaluation by:
- determining a candidate image is a valid image for quality evaluation based at least in part on a composition check of the candidate image or a category check of the candidate image;
- generating features associated with the valid image, wherein the features comprise at least one natural scene statistics based feature and at least one image quality based feature;
- and
- determining an image evaluation indicator associated with the valid image based on a mapping of the generated features to the image evaluation indicator.
