VISUAL SALIENCY ESTIMATION FOR IMAGES AND VIDEO

摘要

Methods and apparatus for deriving a saliency measure for images and video are described. In an embodiment, a process includes decomposing, by a processor, an image into elements, wherein elements cluster the image and each element consists of spatially connected pixels. The processor then calculates a first image measure indicative of each element's uniqueness in the image on a per element basis, and calculates a second image measure indicative of each element's spatial distribution in the image on a per element basis. The processor then provides a per element saliency measure by combining the first image measure and the second image measure.

1. A method for deriving a saliency measure, comprising:
decomposing, by a processor, an image into elements, wherein elements cluster the image and each element consists of spatially connected pixels; calculating, by the processor, a first image measure indicative of each element's uniqueness in the image on a per element basis; calculating, by the processor, a second image measure indicative of each element's spatial distribution in the image on a per element basis; and providing, by the processor, a per element saliency measure by combining the first image measure and the second image measure.
