2D FFT with Simultaneous Edge Artifact Removal

TECHNOLOGY DESCRIPTION

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.

BENEFITS

- Artifact-free processing
- Near-real-time processing
- 100 fps for 2048 x 2048 pixel image
- PXIe based interface based for industrial applications

LIMITATIONS

- Image size
- Frame rate

APPLICATIONS

- High speed industrial tracking
- Image processing
- Medical diagnostics (MRI, CT, etc.)
- Electron microscopy
- Astronomical imaging
