Method and apparatus to recover scene data using re-sampling compressive sensing
First Claim
1. A method comprising:
- obtaining data of a scene;
re-sampling, the data of the scene to obtain re-sampled sensing data of the scene and a corresponding sensing matrix, the re-sampling using a plurality of entries, corresponding to a sampling rate for the data of the scene, and a probability parameter to control creation of the sensing matrix, the creation of the sensing matrix comprising probabilistically assigning values of the sensing matrix by evaluating the entries in the plurality of entries to determine whether a next entry of the plurality of entries indicates that a next value for the sensing matrix is to be a first value with a first probability or a second value with a second probability; and
constructing recovered data of the scene using the re-sampled sensing data of the scene and the corresponding sensing matrix.

Abstract
Methods, computer program products, and computer systems for recovering data of scene are provided. The techniques include: obtaining, by at least one processor, data of a scene; re-sampling, by the at least one processor, the data of the scene to obtain re-sampled sensing data of the scene and a corresponding sensing matrix; and constructing, by the at least one processor, recovered data of the scene using the re-sampled sensing data of the scene and the corresponding sensing matrix. In one embodiment, the method includes enhancing occluded data of the scene to construct the recovered data of the scene, where the recovered data of the scene facilitates identification of the scene. In another embodiment, the method includes compressing original data of a scene, the compressing including sampling the original data of the scene to select the data of the scene.
