Patents by Inventor Philipp Kraehenbuehl

Philipp Kraehenbuehl has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9483709
    Abstract: 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.

  • Patent number: 9330434
    Abstract: Techniques are provided for content-aware video retargeting. An interactive framework combines key frame-based constraint editing with numerous automatic algorithms for video analysis. This combination gives content producers a high level of control of the retargeting process. One component of the framework is a non-uniform, pixel-accurate warp to the target resolution that considers automatic as well as interactively-defined features. Automatic features comprise video saliency, edge preservation at the pixel resolution, and scene cut detection to enforce bilateral temporal coherence. Additional high level constraints can be added by the producer to achieve a consistent scene composition across arbitrary output formats. Advantageously, embodiments of the invention provide a better visual result for retargeted video when compared to using conventional techniques.

  • Patent number: 9025880
    Abstract: 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.
