Choosing a publication venue for an academic paper is crucial step in the research process. However, many cases, decisions are based solely on experience of researchers, which often leads to suboptimal results. Although there exist recommender systems papers, they recommend venues where expected be published. In this study, we aim from different perspective. We estimate number citations will re...

Sketch portrait generation is of wide applications including digital entertainment and law enforcement. Despite the great progress achieved by existing face sketch generation methods, they mostly yield blurred effects and great deformation over various facial parts. In order to tackle this challenge, we propose a novel composition-aided generative adversarial network (CA-GAN) for sketch portrai...

We in this paper solve the problem of high-quality automatic real-time background cut for 720p portrait videos. We first handle the background ambiguity issue in semantic segmentation by proposing a global background attenuation model. A spatial-temporal refinement network is developed to further refine the segmentation errors in each frame and ensure temporal coherence in the segmentation map....

INTODUCTION IN JANUARY 1967 there started the campaign organized by W.H.O. to eradicate smallpox totally. This campaign could not have hoped to succeed without a safe, effective vaccine. Although Edward Jenner probably did not "discover" vaccination, he is usually (and properly) given credit for testing the method and bringing it before the public. Inevitably many engraved portraits of Jenner w...

existence of periodic solutions for non-linear third order autonomous differential equation (o.d.e.) has not been investigated to as large an extent as non-linear second order. the popular poincare-bendixon theorem applicable to second order equation is not valid for third order equation (see [3]). this conclusion opens a way for further investigation.
