Visual saliency estimation for images and video

摘要

Methods and apparatus for visual saliency estimation for images and video are described. In an embodiment, a process includes decomposing, by a processor, an image into elements, wherein each element includes at least one pixel. The processor then calculates a first image measure indicative of each element's uniqueness in the image on a per element basis, and a second image measure indicative of each element's spatial distribution in the image on a per element basis. A per element saliency measure is provided by combining the first image measure and the second image measure, or by utilizing the first image measure, or by utilizing the second image measure.

1. A method, comprising:
decomposing, by a processor, an image into elements, wherein each element comprises at least one pixel; calculating, by the processor using a first Gaussian filter, a first image measure in linear time, the first image measure indicative of each element's uniqueness in the image on a per element basis; calculating, by the processor using a second Gaussian filter, a second image measure in linear time, the 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.
