Subspace-Based Face Recognition in Analog VLSI
We describe an analog-VLSI neural network for face recognition based on subspace methods. The system uses a dimensionality-reduction network whose coefficients can be either progr...

A VLSI Architecture for a Fast Computation of the 2-D Discrete Wavelet Transform
In this paper, an efficient VLSI architecture for a fast computation of the 2-D discrete wavelet transform (DWT) is proposed. The architecture employing a three-stage cascade in p...
