2D FFT with Simultaneous Edge Artifact Removal

managed by Okinawa Institute of Science and Technology


2D Fast Fourier Transforms (FFTs) become a computational constraint for real-time/near real-time systems. FFTs inherently assume that image edges are periodic leading to high amplitude “cross-shaped” artifacts in the frequency domain. These artifacts can be propagated to later stages of processing, adversely affecting decision critical applications, such as, medical diagnostics.

Readiness Level (TRL)

technology validated in lab(The pie chart refers to the entire portfolio contained in the database of the helpdesk)

Technology Readiness Levels (TRL) are a method of estimating technology maturity of Critical Technology Elements (CTE) of a program during the acquisition process. The use of TRLs enables consistent, uniform, discussions of technical maturity across different types of technology.
