Random chopping in ΣΔ modulators
(2009)
Σ∆ modulators make a clever use of oversampling and exhibit inherent monotonicity, high linearity and large dynamic range but a restricted frequency range. As a result Σ∆ modulators are often the preferred option for ...

A VLSI-oriented and power-efficient approach for dynamic texture recognition applied to smoke detection
(2009)
The recognition of dynamic textures is fundamental in processing image sequences as they are very common in natural scenes. The computation of the optic flow is the most popular method to detect, segment and analyse dynamic ...
