We present ViRi -- an intriguing system that enables a user to enjoy a frontal view experience even when the user is actually at a slanted viewing angle. ViRi tries to restore the front-view effect by enhancing the normal content rendering process with an additional geometry correction stage. The necessary prerequisite is effectively and accurately(More)
Neurodegeneration affects cortical gray matter leading to loss of cortical mantle volume. As a result of such volume loss, the geometrical arrangement of the regions on the cortical surface is expected to be altered in comparison to healthy brains. Here we present a novel method to study the alterations in brain cortical surface geometry in Parkinson’s(More)
Mobile phones have become an ideal platform for physiological and environmental sensing. A number of research and commercial smartphone "accessories" have emerged in recent years that try to extend the sensing capabilities of a mobile phone. However, the major drawback of these devices is that they either require the user to act in some specific way or(More)
Blind restoration of blurry image is a challenging and significant problem. In this paper, we propose a deblurring algorithm which restores the latent image from a single blurry image. The method consists of two parts, kernel estimation and image restoration. To estimate the blur kernel, a cost function is constructed using a regularization term based on(More)
