Techniques are disclosed for parallel computing of a line of sight (LoS) map (e.g., view-shed) in a parallel computing system. For example, a method for computing an LoS map comprises the following steps. Data representing at least one image is obtained. An observation point in the at least one image is identified. A portion of the data that is associated with a given area in the image is partitioned into a plurality of sub-areas. The plurality of sub-areas are assigned to a plurality of processor elements of a parallel computing system, respectively, such that the data associated with each one of the plurality of sub-areas is processed independent from the data associated with each other of the plurality of sub-areas, wherein results of the processing by the processor elements represents the LoS map. The parallel computing system may be a multicore processor.
A method for computing a line of sight (LoS) map, comprising:
A parallel computing system for computing a line of sight (LoS) map, the parallel computing system comprising a plurality of processor elements, wherein the parallel computing system is configured to:
An article of manufacture for computing a line of sight (LoS) map for use in a parallel computing system comprising a plurality of processor elements, the article of manufacture comprising a computer readable storage medium tangibly embodying a computer readable program code which, when executed by the parallel computing system, causes the parallel computing system to:
