In this paper, the concept of compressive acquisitive image sensor is extended to the temporal domain. Architecture of a compact CMOS image sensor designed based on the design paradigm capture??compress??store is proposed. The image sensor array is divided into quadrants. Spatial compression algorithm is integrated into quadrant-level circuit and carried out on-line before the storage phase. All the...
In this paper, a reconflgurable multi-precision Radix-4 Booth multiplier structure is presented. The reconfig- urable 8 x 8 bit multiplier unit can be cascaded to form a multiplier that can adapt to variable input precision requirements. The number of bits can be extended by concatenating more stages together. For example, four 8 x8 bit units can be used to build a 16 x 16 bit Booth multiplier. In...
Gaussian mixture models (GMM)-based classifiers have shown increased attention in many pattern recognition applications. Improved performances have been demonstrated in many applications, but using such classifiers can require large storage and complex processing units due to exponential calculations and a large number of coefficients involved. This poses a serious problem for portable real-time pattern...
