Method and apparatus to recover scene data using re-sampling compressive sensing

A computer system comprising:

• a memory;
• and
• at least one processor in communication with the memory, wherein the computer system is configured to perform a method, said method comprising:
• obtaining, by the 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, the re-sampling using a series 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 series of entries to determine whether a next entry of the series 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, 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.
