Patent number: 11373272Abstract: A system and method for improving the detail of a digital signal comprising at least three dimensions can be implemented by extracting a plurality of data cubes containing two x-planes, two y-planes, two z-planes, and amplitude information at eight locations in this x, y, and z space. A primary and secondary direction and a data plane for each data cube can then be selected based on difference calculations of eight locations in the x, y, and z directions, resulting in a 2×2 data square. This data square can then be used to compute a network neighborhood, which can subsequently be used to calculate first and second order gradient information. The first and second order gradient information can be used to construct an output signal that has greater detail than the input signal.Type: GrantFiled: November 23, 2020Date of Patent: June 28, 2022Assignee: MindAptiv, LLCInventors: John J.
