Abstract
This disclosure provides systems, methods, and devices for image processing that support noise reduction in low-light video sequences. The noise reduction is accomplished through a cascaded set of operations that are configured based on each set of operations location within the cascaded pipeline. The cascade may be implemented as a series of cascaded image post-processing engines (IPEs) within an image signal processor (ISP).
