Image restoration has been a research topic deeply investigated within the last two decades. As is well-known, total variation (TV) minimization by Rudin, Osher, and Fatami [6] offers superior image restoration quality and involves solving a second order nonlinear partial differential equation (PDE). In more recent years, some effort has been made in(More)
Noises in videos can occur during recording and transmission. The advancement of the processor technology makes real time video denoising possible on multicore processors. In this paper, we investigate parallel techniques for denoising the real-time video on a multi-core processor. We compare two strategies: a block strategy, which assigns a group of(More)
The ultrasound videos are mainly contaminated by multiplicative noises but also contaminated with additive noises. As the past few decades, there are some studies to remove the noises from ultrasound images as in the JY model [1] and the variational model which removes both types of noises. However, denoising these noises from the ultrasound video is the(More)
In this paper, we proposed a new parallel iterative asynchronous method for Gauss-Seidel and Successive Over-Relaxation (SOR) for finite difference method (FDM) and finite element method (FEM). The approach attempts to minimize the thread synchronization which incurs a lot of thread idle time due to the dependency of computation. Our proposed method(More)
