Acquiring images of the same anatomy with multiple different contrasts increases diversity diagnostic information available in an MR exam. Yet, scan time limitations may prohibit acquisition certain contrasts, and some be corrupted by noise artifacts. In such cases, ability to synthesize unacquired or can improve utility. For multi-contrast synthesis, current methods learn a nonlinear intensity transformation between source target images, either via regression deterministic neural networks....

Recent years have witnessed the emergence of new image smoothing techniques which provided insights and raised questions about nature this well-studied problem.

In study, we propose an alternative yet simple approach depends on covariance matrices features, aka region covariances. The use second order...

Automatic image synthesis research has been rapidly growing with deep networks getting more and expressive. In the last couple of years, we have observed images digits, indoor scenes, birds, chairs, etc. being automatically generated.

Previous sampling-based image matting methods typically rely on certain heuristics in collecting representative samples from known regions, and thus their performance deteriorates if the underlying assumptions are not satisfied. To alleviate this, this paper we take an entirely new approach formulate sampling as a sparse subset selection problem where propose to pick small set of candidate that best explains unknown pixels. Moreover, describe distance measure for comparing two which is based...

In this study, we explore building a two-stage framework for enabling users to directly manipulate high-level attributes of natural scene. The key our approach is deep generative network that can hallucinate images scene as if they were taken in different season (e.g., during winter), weather condition on cloudy day), or at time the day sunset). Once hallucinated with given attributes, corresponding look then transferred input image while preserving semantic details intact, giving...

Since the invention of cameras, video shooting has become a passion for human. However, quality videos recorded with devices such as handheld head and vehicle cameras may be low due to shaking, jittering unwanted periodic movements. Although issue stabilization been studied decades, there is no consensus on how measure performance method. In many studies in literature, different metrics have used comparison methods. this study, deep convolutional neural networks are decision maker...

In recent years, deep learning approach to solve the image and video processing problems have become very popular. Generative Adversarial Networks (GANs) are one of most popular learning-based models. GANs form a generative model utilizing two sub-models, namely, generator discriminator. The tries generate indistinguishably realistic outputs where discriminator tires classify as real or fake. These models work together achieve successful generation outputs. This study aims reconstruct...

Video stabilization is the process of eliminating unwanted camera movements and shaking in a recorded video. Recently, learning-based video methods have become very popular.
