This paper describes a method for video sequences denoising that exploits extra-information provided by the image sensor. Fixed Pattern Noise and Temporal Noise are removed by analyzing a series of lines placed at the top of the imager. Index Terms — Noise Reduction, Fixed Pattern Noise, Temporal Random Noise.
This paper describes a temporal filter aimed to the simultaneous cancellation of fixed pattern noise and temporal noise from image sequences by exploiting all the data provided by a typical image sensor (e.g. CCD/CMOS).
A CMOS image sensor that employs a vertically integrated double junction photodiode structure is presented. This allows colour imaging with only two, wider bandwidth, filters. The sensor uses a 184 x 154 6-transistor pixel array at a 9.6 μm pitch. Results of the device characterisation, and colour image reconstruction using the prototype sensor, are… (More)
An accurate model of CMOS image sensor noise performance is useful in optimising sensor design and setting targets, ultimately leading to improvements in image quality. Many attempts at modelling CMOS image sensor noise are based on over-simplistic assumptions and may not incorporate a sufficient variety of noise sources to yield a realistic simulator… (More)
A cost-optimized 40nm CMOS integrated powerline communications SoC is presented. This SoC includes all the analog and digital components required for the HomePlugAV standard. Circuit techniques for the RXPGA and TX line driver are described. The powerline SoC can achieve full HPAV 200Mbps PHY rate and operates with a 96dB channel dynamic range with low… (More)
