Geometry-Aware Face Completion and Editing

Face completion is a challenging generation task because it requires generating visually pleasing new pixels that are semantically consistent with the unmasked face region. This paper proposes a geometry-aware Face Completion and Editing NETwork (FCENet) by systematically studying facial geometry from the unmasked region. Firstly, a facial geometry estimator is learned to estimate facial landmark heatmaps and parsing maps from the unmasked face image. Then, an encoder-decoder structure generator serves to complete a face image and disentangle its mask areas conditioned on both the masked face image and the estimated facial geometry images. Besides, since low-rank property exists in manually labeled masks, a low-rank regularization term is imposed on the disentangled masks, enforcing our completion network to manage occlusion area with various shape and size. Furthermore, our network can generate diverse results from the same masked input by modifying estimated facial geometry, which provides a flexible mean to edit the completed face appearance. Extensive experimental results qualitatively and quantitatively demonstrate that our network is able to generate visually pleasing face completion results and edit face attributes as well

Vertical velocity observations of a FIRE II cirrus event

July 1994.Includes bibliographical references.The development of doppler radar wind profilers and their subsequent deployment have dramatically improved the spatial and temporal resolutions of wind observations. While the horizontal winds deduced from these observations are generally reliable, serious questions remain on the ability to reliably observe the vertical wind component. In an upper tropospheric cirrus cloud environment often characterized by weak backscatter signal strength, small magnitude vertical motions, high altitude and short life cycle, this problem is especially difficult. A review of the echo generating mechanisms for a 400 MHz radar system is presented. This study further examines the feasibility of determining reliable vertical motion fields from both individual and a network of wind profiler observations. Data employed in this research were collected during the FIRE II experiment in November and December of 1991. Vertical motions were calculated in three ways: directly from the doppler radial velocity observations, from a quasi-V AD method utilizing the four non-zenith profiler beams, and by applying the kinematic method to profiler network data. The deduced vertical wind fields from each method are compared. This research also includes a diagnostic study of a jet streak system observed on 26 November 1991; this study emphasizes the thermal and dynamic instability structures, the vertical forcing the ageostrophic circulation. Results from the diagnostic and previous theoretical studies are compared with the vertical velocity fields deduced from wind profiler observations.Sponsored by the National Aeronautics and Space Administration NAG 1-1146, and the Department of Energy DE-FG02-90ER60970
