In this work, we focus on a challenging task: synthesizing multiple imaginary videos given a single image. Major problems come from high dimensionality of pixel space and the ambiguity of potential motions. To overcome those problems, we propose a new framework that produce imaginary videos by transformation generation. e generated transformations are applied to the original image in a novel volumetric merge network to reconstruct frames in imaginary video. rough sampling di erent latent variables, our method can output di erent imaginary video samples. e framework is trained in an adversarial way with unsupervised learning. For evaluation, we propose a new assessment metric RIQA. In experiments, we test on 3 datasets varying from synthetic data to natural scene. Our framework achieves promising performance in image quality assessment. e visual inspection indicates that it can successfully generate diverse ve-frame videos in acceptable perceptual quality.

Previous works on font generation mainly focus on the standard print fonts where character's shape is stable and strokes are clearly separated. There is rare research on brush handwriting font generation, which involves holistic structure changes and complex strokes transfer. To address this issue, we propose a novel GAN-based image translation model by integrating the skeleton information. We first extract the skeleton from training images, then design an image encoder and a skeleton encoder to extract corresponding features. A self-attentive refined attention module is devised to guide the model to learn distinctive features between different domains. A skeleton discriminator is involved to first synthesize the skeleton image from the generated image with a pre-trained generator, then to judge its realness to the target one. We also contribute a large-scale brush handwriting font image dataset with six styles and 15,000 high-resolution images. Both quantitative and qualitative experimental results demonstrate the competitiveness of our proposed model.

In this paper, we present a novel system (denoted as Polaca) to generate poetic Chinese landscape painting with calligraphy. Unlike previous single image-to-image painting generation, Polaca takes the classic poetry as input and outputs the artistic landscape painting image with the corresponding calligraphy. It is equipped with three different modules to complete the whole piece of landscape painting artwork: the first one is a text-to-image module to generate landscape painting image, the second one is an image-to-image module to generate stylistic calligraphy image, and the third one is an image fusion module to fuse the two images into a whole piece of aesthetic artwork.

Herbal extracts interfere with bacterial adhesion and support apoptosis-dependent exfoliation to protect mammals against bacterial infection. In this study, juvenile yellow catfish were fed with control diet or Acanthopanax senticosus extracts (AS)supplemented diet. After 60 days, AS (180 ml/kg feed) significantly elevated fish growth and feed utilization, with higher weight gain and feed efficiency. After challenged with Edwardsiella ictaluri, survival rate of AS-supplemented fish (65%) was significantly higher than control fish (30%). Control fish exhibited obvious skin lesions since 1 day post-infection (dpi) and decreased thickness of epidermis with prolonged days, while AS-supplemented fish skin structure showed better integrity. Moreover, length of secondary branchial filaments of AS-supplemented fish was higher than control fish that showed obvious occlusion between adjacent lamellae. Unlike its proinflammatory role in spleen, AS significantly inhibited gill inflammation at 4 dpi via regulating TLRs-NFκB pathway. Moreover, haematoxylin-eosin staining exhibited that AS delayed the liver vasculitis and necrotic hepatitis of yellow catfish. Further study by TUNEL assay, caspase-3 activity and mRNA expression indicated that AS significantly promoted hepatic apoptosis at 1 dpi to prevent further necrosis, which process was regulated by JAK/STAT pathway. All results demonstrated AS modulated inflammation and apoptosis to protect yellow catfish against Edwardsiella ictaluri infection.
