COordinate Rotation Digital computer (CORDIC) is a unit that is widely used in the applications such as scientific calculators, signal/imageprocessing, communication systems, robotics, 3-D graphics etc. exhibits huge computations and requires large power. this paper presents an approximate low power Repetitive Iteration CORDIC (RICO) architecture that calculates sine/cosine values very efficiently. In the proposed RICO, number of iterations are fixed and a specific iteration is repeated to reduce the implementation complexity. An additional comparator based logic that evaluates direction of micro-rotation within RICO reduces the data dependency between each iterations. the efficiency of the proposed RICO is evaluated in Discrete Cosine Transform (DCT) by implementing DCT using only three RICO units. Post-synthesis simulation results show that the proposed RICO achieves area and power savings of 37.19% and 94.05% respectively over the Conventional CORDIC at the cost of 29.39% increase in latency.

An image captured in dark environment usually has ambient illumination, but the image looks dark and noisy. However, the use of flash can introduce unwanted artifacts such as sharp shadows at silhouettes, red eyes, and non-uniform brightness in the image. We propose a new framework to enhance photographs captured in dark environments by combining the best features from a flash and a no-flash image. We use sparse and redundant dictionary learning based approach to denoise the no-flash image. A weighted least squares framework is used to transfer sharp details from the flash image into the no-flash image. We show that our approach is simple and able to generate better images than that of the state-of-the-art flash/no-flash fusion method.
