DeepNude-an-Image-to-Image-technology

This repository contains the pix2pixHD algorithms(proposed by NVIDIA) of DeepNude, and more importantly, the general image generation theory and practice behind DeepNude.

这个仓库包含DeepNude的pix2pixHD(由英伟达提出)算法,更重要的是DeepNude背后通用的图像生成理论与实践研究。

What is DeepNude? 什么是 DeepNude?

DeepNude uses a slightly modified version of the pix2pixHD GAN architecture, quoted from deepnude_official. pix2pixHD is a general-purpose Image2Image technology proposed by NVIDIA. Obviously, DeepNude is the wrong application of artificial intelligence technology, but it uses Image2Image technology for researchers and developers working in other fields such as fashion, film and visual effects.

DeepNude使用了一个稍微修改过的 pix2pixHD GAN 架构。pix2pixHD是由NVIDIA提出的一种通用的Image2Image技术。显然,DeepNude是人工智能技术的错误应用,但它使用的Image2Image技术对于在时尚,电影和视觉效果等其他领域工作的研究人员和开发人员非常有用。

1. Pix2Pix

效果

Image-to-Image Translation with Conditional Adversarial Networks is a general solution for the use of conditional confrontation networks as an image-to-image conversion problem proposed by the University of Berkeley.

Image-to-Image Translation with Conditional Adversarial Networks 是伯克利大学研究提出的使用条件对抗网络作为图像到图像转换问题的通用解决方案。

2. Pix2PixHD

DeepNude mainly uses this Image-to-Image(Pix2PixHD) technology.

效果

Get high resolution images from the semantic map. The semantic graph is a color picture. The different color blocks on the map represent different kinds of objects, such as pedestrians, cars, traffic signs, buildings, and so on. Pix2PixHD takes a semantic map as input and produces a high-resolution, realistic image. Most of the previous techniques can only produce rough, low-resolution images that don't look real. This research has produced images with a resolution of 2k by 1k, which is very close to full HD photos.

从语义图上获得高分辨率图片。语义图是一幅彩色图片,图上的不同色块代表不同种类物体,如行人、汽车、交通标志、建筑物等。Pix2PixHD将一张语义图作为输入,并由此生成了一张高分辨率的逼真的图像。之前的技术多数只能生成粗糙的低分辨率的图片,看起来也不真实。而这个研究却生成了2k乘1k分辨率的图像,已经很接近全高清的照片。

3. CycleGAN

效果

CycleGAN uses a cycle consistency loss to enable training without the need for paired data. In other words, it can translate from one domain to another without a one-to-one mapping between the source and target domain. This opens up the possibility to do a lot of interesting tasks like photo-enhancement, image colorization, style transfer, etc. All you need is the source and the target dataset.

CycleGAN使用循环一致性损失函数来实现训练,而无需配对数据。换句话说,它可以从一个域转换到另一个域,而无需在源域和目标域之间进行一对一映射。这开启了执行许多有趣任务的可能性,例如照片增强,图像着色,样式传输等。您只需要源和目标数据集。

4. StyleGAN

效果

Source A + Source B (Style) = ?

StyleGAN can not only generate fake images source A and source B, but also combine the content of source A and source B from different strengths, as shown in the following table.

StyleGAN 不仅可以生成假的图片source A 和 source B,还可以结合从不同的力度上结合source A的内容和 source B的样式,具体说明如下表。

Style 等级(源自 Source B) Source A Source B
高等级(粗略) 所有颜色(眼睛,头发,光线)和细节面部特征来自Source A 继承Source B高级的面部特征,如姿势、一般的发型、脸部形状和眼镜
中等级 姿势、一般的面部形状和眼镜来自Source A 继承Source B中级的面部特征 ,如发型,张开/闭着的眼睛
高等级(细微) 主要面部内容来自Source A 继承Source B高级面部特征,如颜色方案和微观结构

5. Image Inpainting 图像修复

效果

In the image interface of Image_Inpainting(NVIDIA_2018).mp4 video, you only need to use tools to simply smear the unwanted content in the image. Even if the shape is very irregular, NVIDIA's model can “restore” the image with very realistic The picture fills the smeared blank. It can be described as a one-click P picture, and "no ps traces." The study was based on a team from Nvidia's Guilin Liu et al. who published a deep learning method that could edit images or reconstruct corrupted images, even if the images were worn or lost pixels. This is the current 2018 state-of-the-art approach.

Image_Inpainting(NVIDIA_2018).mp4 视频中左侧的操作界面,只需用工具将图像中不需要的内容简单涂抹掉,哪怕形状很不规则,NVIDIA的模型能够将图像“复原”,用非常逼真的画面填补被涂抹的空白。可谓是一键P图,而且“毫无ps痕迹”。该研究来自Nvidia的Guilin Liu等人的团队,他们发布了一种可以编辑图像或重建已损坏图像的深度学习方法,即使图像穿了个洞或丢失了像素。这是目前2018 state-of-the-art的方法。
