Abstract
A computer-implemented system and method for predicting an image quality of an image are disclosed. For an input image, the method includes generating a first descriptor based on semantic content information for the image and generating a second descriptor based on aesthetic features extracted from the image. With a categorizer which has been trained to assign a quality value to an image based on first and second descriptors, a quality value is assigned to the image based on the first and second descriptors and output.
Claims23
A method for predicting an image quality of an image comprising:
- for an input image:
- generating a first descriptor based on semantic content information for the image;
- generating a second descriptor based on aesthetic features extracted from the image;
- with a categorizer which has been trained to assign a quality value to an image based on first and second descriptors, assigning a quality value to the image based on the first and second descriptors;
- and
- outputting the image quality value.
A system for generating an image quality assessment for an image comprising:
- memory which stores:
- a content feature extractor for generating a first descriptor based on semantic content information for an input image;
- an aesthetic feature extractor for generating a second descriptor based on aesthetic features extracted from the image;
- and
- a categorizer which has been trained to assign a quality value to an image based on the first and second descriptors;
- and
- a computer processor in communication with the memory for implementing the extractors and categorizer.
