Efficient image reconstruction using partial 2D Fourier transform
In this paper we present an efficient way of doing image reconstruction using the 2D Discrete Fourier transform (DFT). We exploit the fact that in the frequency domain, informati...

Adaptive Spatial and Transform Domain FGS Coding
In inter-picture coding, block-based frequency transform is usually carried out on the predicted errors for each interblock to remove the spatial correlation among them. However, ...
