Spiral FFT: An efficient method for 3-D FFTS on spiral MRI contours
The Fast Fourier Transform (FFT) allows the Discrete Time Fourier Transform (DTFT) to be efficiently sampled on a uniform grid in frequency. In many applications, including Magnet...

Generalised Parallel Bilinear Interpolation Architecture for Vision Systems
Bilinear interpolation is widely used in computer vision for extracting pixel values for positions that lie off the pixel grid in an image. For each sub-pixel, the values of four ...

Progressive RBF interpolation
Interpolation based on Radial Basis Functions (RBF) is very often used for scattered scalar data interpolation in n-dimensional space in general. RBFs are used for surface reconst...

Color filter array interpolation based on spatial adaptivity
Conventional approach in single-chip digital cameras is a use of color lter arrays (CFA) in order to sample di erent spectral components. Demosaicing algorithms interpolate these ...

3D Head Tracking Based on Recognition and Interpolation Using a Time-of-Flight Depth Sensor
This paper describes a head-tracking algorithm that is based on recognition and correlation-based weighted interpolation. The input is a sequence of 3D depth images generated by a...
