StaRSaC: Stable Random Sample Consensus for Parameter Estimation
We address the problem of parameter estimation in presence of both uncertainty and outlier noise. This is a common occurrence in computer vision: feature localization is perform...

Nonconvex compressive sensing and reconstruction of gradient-sparse images: Random vs. tomographic Fourier sampling
Previous compressive sensing papers have considered the example of recovering an image with sparse gradient from a surprisingly small number of samples of its Fourier transform. T...

Efficient product sampling using hierarchical thresholding
Abstract We present an efficient method for importance sampling the product of multiple functions. Our algorithm computes a quick approximation of the product on-the-fly, based on ...

A CMOS direct sampling mixer using Switched Capacitor Filter technique for software-defined radio
This paper proposes a novel direct sampling mixer (DSM) using Switched Capacitor Filter (SCF) for multi-band receivers. The proposed DSM has a higher gain, more flexibility and low...
