摘要： A method of processing a set of images of a scene is disclosed. The set is represented by a plurality of picture-elements defining an image plane, and the images are characterized by different light intensity spatial distributions but the same viewpoint relative to the scene. The method comprises: for each of at least some picture-elements, independently selecting a direction parallel to the image plane, constructing a weighted vector field based on the selected direction, and calculating a height of a surface in the scene perpendicular to the image plane based on the constructed weighted vector field. The method further comprises reconstructing a three-dimensional spatial representation of the surface based on the heights; and transmitting the spatial representation to a computer readable medium.

摘要： A method comprising: mapping an image onto multiple level sets connected by multiple branches, wherein each of said level sets corresponds to a predefined range of values for an attribute of said image; associating multiple pixels of said image to said multiple level sets in accordance with the value of each pixel; identifying a source level set associated with a source pixel of said multiple pixels; for each of said multiple pixels, determining that a distance between said source pixel and one of said multiple pixels is within a predefined threshold, wherein said distance is calculated as a function of a first distance between said source level set and said level set associated with said one of said multiple pixels; in one embodiment, the determined distance is applied to an image processing application to produce a processed image, and the processed image is rendered on a rendering medium.

摘要： A method training a randomized decision tree through multiple iterations, each is based on: a) Receiving multiple data samples that include data subsets, each data subset corresponds to an attribute. b) Distributing the data subsets to slave processing units after sorting the data samples in consecutive ascending order by updating a first index that identifies trajectories of the training data samples through the tree nodes of the previous tree level. c) Simultaneously processing the data subsets to identify split functions for each tree node with respect to each data subset and updating a second index that identifies the trajectories of the training data samples through the tree node of the current tree level. d) Collecting the split functions from the slave processing units and constructing the current tree level by selecting a preferred split function for each tree node of the current tree level.
