摘要： A method of decomposing a set of scans of different views of overlapping objects into constituent objects is presented. The method involves an initialization process whereby keypoints in two views are determined and matched, disparity between keypoint pairs are computed, and the keypoints are grouped into clusters based on their disparities. Following the initialization process is an iterative optimization process whereby a cost function is calculated and minimized assuming a fixed composition matrix and re-solved assuming a fixed attenuation coefficient. Then, the composition matrix and the attenuation coefficient are updated simultaneously, and the solving, the re-solving, and the updating steps are repeated until there is no significant improvement in the result.

摘要： A method and system for scheduling events into a set of opportunities is presented. The method includes 1) dividing a path of an image acquisition device so that there is at least a first portion and a second portion at any given moment, wherein each of the first portion and the second portion includes at least one state and the first portion includes a null state in which no image is taken; 2) combining each state in the first portion with at least one state in the second portion one by one to generate a series of updated sequences; and 3) selecting at least one of the updated sequences based on a merit value associated with each of the updated sequences. The invention uses only two groups out of all the relevant opportunities for most calculations, and is especially applicable to situations like satellite pass scheduling.
