Abstract
An apparatus, method and an image quality guide document are disclosed. The method includes, for at least one image in a set of images undergoing image enhancement, identifying image quality-related features for the image based on enhancements being applied to the image, identifying image content-related features based on content of the image, determining a content-based degradation of the image based on the identified image quality-related features and image content-related features, and generating a thumbnail of the image. The method further includes generating an image quality guide document for the set of images in which at least one of the thumbnails is associated with a respective text description that is based on the determined content-based degradation.
Claims19
An automated method for generating an image quality guide document, comprising:
- for at least one image in a set of images undergoing image enhancement:
- identifying image quality-related features for the image based on enhancements being automatically applied to the image,
- identifying image content-related features based on content of the image,
- determining a content-based degradation of the image based on the identified image quality-related features and image content-related features, and
- retrieving a photograph shooting tip for correcting the degradation in the image, based on the determined content-based degradation;
- and
- generating an image quality guide document for the images in the set of images in which a visual representation of at least one of the images is associated with a respective text description that is based on the determined content-based degradation and that includes the shooting tip associated with the image for avoiding the content-based degradation.
An apparatus for generating an image quality guide document for a set of images, comprising:
- an enhancement detector which outputs image quality-related features for images in the set based on enhancements being applied to the images;
- an image content analyzer which outputs image semantic content-related features for images in the set, the image content analyzer identifying low level features of the image and classifying the image based on the low level features using a classifier which has been trained on images that are each manually assigned to a semantic category selected from a set of predefined semantic content based categories;
- a degradation classifier which receives the output image quality-related features and image semantic content-related features and outputs a content-based degradation for at least one of the images in the set;
- and
- an image quality guide document generator which generates an image quality guide document for the set of images in which at least one of the images is associated with a respective text description that is based on the determined content-based degradation.
An image quality guide document rendered in tangible media which includes an arrangement for a set of processed images and automatically generated associated text descriptions associated with at least some of the images, each text description describing a content-based degradation of the image, an image enhancement applied to correct the degradation and, for at least one of the images, a respective shooting tip for avoiding the content-based degradation.
An image processing method comprising:
- applying at least one automated image enhancement to at least one of a set of input images to generate a set of enhanced images including automatically evaluating image quality features for the input image to determine whether the image meets predetermined acceptable values for the image quality features;
- identifying image quality-related features for the at least one input image based on a stored log of the at least one applied enhancement;
- identifying image content-related features based on content of the at least one image;
- and
- generating an image quality guide document for the set of images in which at least one of the images is associated with a respective text description that is based on the identified image quality-related features and image content-related features.
