Computed tomography (CT) detectors require wide dynamic range (DR) and high linearity. This paper reports the design of a new CMOS pixel with in-pixel acquisition front-end for CT in a 0.35 mum CMOS process. The detector uses a synchronous partial quantization scheme to linearly expand the dynamic range with a constant potential well size. A low-power analog-to-digital converter is also designed in...
A fast super-resolution reconstruction algorithm designed for license plate recognition is proposed in this paper. It uses a new reduced cost function to produce images of higher resolution from low resolution frame sequences. Computational cost required in this algorithm is much lower compared with other methods. The effectiveness of the proposed algorithm is demonstrated through blind reconstruction...
A fast super-resolution reconstruction algorithm is proposed in this paper. It uses a new reduced cost function to produce images of higher resolution from low resolution frame sequences. The result photos can greatly promote the recognition rate, and reduce the hardware requirements for imaging system. Blind reconstruction experiments using real videos of moving vehicles showed that the proposed...
