    Abstract: Described herein is an object recognition system in low illumination conditions. A 3D InIm system can be trained in the low illumination levels to classify 3D objects obtained under low illumination conditions. Regions of interest obtained from 3D reconstructed images are obtained by de-noising the 3D reconstructed image using total-variation regularization using an augmented Lagrange approach followed by face detection. The regions of interest are then inputted into a trained CNN. The CNN can be trained using 3D InIm reconstructed under low illumination after TV-denoising. The elemental images were obtained under various low illumination conditions having different SNRs. The CNN can effectively recognize the 3D reconstructed faces after TV-denoising.

  • Patent number: 11363228
    Abstract: Techniques are described for implementing ramp voltage generators with current steering architectures that provide high power supply noise rejection. For example, a current steering architecture uses a sample and hold block and a driver block to control and drive a current steering network. Both generate signals that track supply voltage variations, and those signals are used to generate a ramp voltage. For image sensor applications, image tolerance to ramp noise can be very low when the ramp voltage is low, but can increase appreciably as the ramp voltage increases. As such, embodiments can be implemented to provide high PSR at low ramp voltages, even if the PSR degrades at higher ramp voltages, while maintaining high linearity over the entire ramp voltage.
