Their official code (using Torch) can be found \n[here](https:\u002F\u002Fgithub.com\u002Fcoupriec\u002FVideoPredictionICLR2016).\n\nAdversarial generation uses two networks – a generator and a discriminator – to improve the sharpness of generated images. Given the past four frames of video, the generator learns to generate accurate predictions for the next frame. Given either a generated or a real-world image, the discriminator learns to correctly classify between generated and real. The two networks \"compete,\" with the generator attempting to fool the discriminator into classifying its output as real. This forces the generator to create frames that are very similar to what real frames in the domain might look like.\n\n## Results and Comparison\nI trained and tested my network on a dataset of frame sequences from Ms. Pac-Man. To compare adversarial \ntraining vs. non-adversarial, I trained an adversarial network for 500,000 steps on both the generator and \ndiscriminator, and I trained  a non-adversarial network for 1,000,000 steps (as the non-adversarial network \nruns about twice as fast). Training took around 24 hours for each network, using a GTX 980TI GPU.\n\nIn the following examples, I ran the networks recursively for 64 frames. (i.e. The input to generate the first frame was [input1, input2, input3, input4], the input to generate the second frame was [input2, input3, input4, generated1], etc.). As the networks are not fed actions from the original game, they cannot predict much of the true motion (such as in which direction Ms. Pac-Man will turn). Thus, the goal is not to line up perfectly with the ground truth images, but to maintain a crisp and likely representation of the world.\n\nThe following example exhibits how quickly the non-adversarial network becomes fuzzy and loses definition of the sprites. The adversarial network exhibits this behavior to an extent, but is much better at maintaining sharp representations of at least some sprites throughout the sequence:\n\n\u003Cimg src=\"https:\u002F\u002Foss.gittoolsai.com\u002Fimages\u002Fdyelax_Adversarial_Video_Generation_readme_f9584dc79d18.gif\" width=\"100%\" \u002F>\n\nThis example shows how the adversarial network is able to keep a sharp representation of Ms. Pac-Man around multiple turns, while the non-adversarial network fails to do so:\n\n\u003Cimg src=\"https:\u002F\u002Foss.gittoolsai.com\u002Fimages\u002Fdyelax_Adversarial_Video_Generation_readme_0946cd52839d.gif\" width=\"100%\" \u002F>\n\nWhile the adversarial network is clearly superior in terms of sharpness and consistency over time, the non-adversarial network does generate some fun\u002Fspectacular failures:\n\n\u003Cimg src=\"https:\u002F\u002Foss.gittoolsai.com\u002Fimages\u002Fdyelax_Adversarial_Video_Generation_readme_3eeb340c8352.gif\" width=\"50%\" \u002F>\n\nUsing the error measurements outlined in the paper (Peak Signal to Noise Ratio and Sharp Difference) did not show significant difference between adversarial and non-adversarial training. I believe this is because sequential frames from the Ms. Pac-Man dataset have no motion in the majority of pixels, while the original paper was trained on real-world video where there is motion in much of the frame. Despite this, it is clear that adversarial training produces a qualitative improvement in the sharpness of the generated frames, especially over long time spans. You can view the loss and error statistics by running `tensorboard --logdir=.\u002FResults\u002FSummaries\u002F` from the root of this project.\n\n## Usage\n\n1. Clone or download this repository.\n2. Prepare your data:\n  - If you want to replicate my results, you can [download the Ms. Pac-Man dataset here](https:\u002F\u002Fdrive.google.com\u002Ffile\u002Fd\u002F0Byf787GZQ7KvV25xMWpWbV9LdUU\u002Fview?usp=sharing&resourcekey=0-Vequaxb8kl0m_NIzJJt52g). Put this in a directory named `Data\u002F` in the root of this project for default behavior. Otherwise, you will need to specify your data location using the options outlined in parts 3 and 4.\n  - If you would like to train on your own videos, preprocess them so that they are directories of frame sequences as structured below. (Neither the names nor the image extensions matter, only the structure):\n  ```\n    - Test\n      - Video 1\n        - frame1.png\n        - frame2.png\n        - frame ...\n        - frameN.png\n      - Video ...\n      - Video N\n        - ...\n    - Train\n      - Video 1\n        - frame ...\n      - Video ...\n      - Video N\n        - frame ...\n  ```\n3. Process training data:\n  - The network trains on random 32x32 pixel crops of the input images, filtered to make sure that most clips have some movement in them. To process your input data into this form, run the script `python process_data` from the `Code\u002F` directory with the following options:\n  ```\n  -n\u002F--num_clips= \u003C# clips to process for training> (Default = 5000000)\n  -t\u002F--train_dir= \u003CDirectory of full training frames>\n  -c\u002F--clips_dir= \u003CSave directory for processed clips>\n                  (I suggest making this a hidden dir so the filesystem doesn't freeze\n                   with so many files. DON'T `ls` THIS DIRECTORY!)\n  -o\u002F--overwrite  (Overwrites the previous data in clips_dir)\n  -H\u002F--help       (prints usage)\n  ```\n  - This can take a few hours to complete, depending on the number of clips you want.\n  \n4. Train\u002FTest:\n  - If you want to plug-and-play with the Ms. Pac-Man dataset, you can [download my trained models here](https:\u002F\u002Fdrive.google.com\u002Ffile\u002Fd\u002F0Byf787GZQ7KvR2JvMUNIZnFlbm8\u002Fview?usp=sharing&resourcekey=0-nKmDhxA54ZXtQKql_45DdA). Load them using the `-l` option. (e.g. `python avg_runner.py -l .\u002FModels\u002FAdversarial\u002Fmodel.ckpt-500000`).\n  - Train and test your network by running `python avg_runner.py` from the `Code\u002F` directory with the following options:\n  ```\n  -l\u002F--load_path=    \u003CRelative\u002Fpath\u002Fto\u002Fsaved\u002Fmodel>\n  -t\u002F--test_dir=     \u003CDirectory of test images>\n  -r--recursions=    \u003C# recursive predictions to make on test>\n  -a\u002F--adversarial=  \u003C{t\u002Ff}> (Whether to use adversarial training.

Why not train on the whole image?\n\nMemory usage. Since the discriminator has fully-connected layers after the convolutions, the output of the last convolution must be flattened to connect to the first fully-connected layer. The size of this output is dependent on the input image size, and blows up really quickly (e.g. For an input size of 64x64, going from 128 feature maps to a fully connected layer with 512 nodes, you need a connection with 64 * 64 * 128 * 512 = 268,435,456 weights). Because of this, training on patches larger than 32x32 causes an out-of-memory error (at least on my machine).\n\nLuckily, you only need the discriminator for training, and the generator network is fully convolutional, so you can test the weights you trained on 32x32 images over images of any size (which is why I'm able to do generations for the entire Ms. Pac-Man board).\n","# 对抗视频生成\n本项目实现了一个生成对抗网络 (Generative Adversarial Network) 来预测视频的未来帧，详见 Mathieu, Couprie & LeCun 撰写的 [\"Deep Multi-Scale Video Prediction Beyond Mean Square Error\"](https:\u002F\u002Farxiv.org\u002Fabs\u002F1511.05440)。他们的官方代码（使用 Torch）可以在 [这里](https:\u002F\u002Fgithub.com\u002Fcoupriec\u002FVideoPredictionICLR2016) 找到。\n\n对抗生成使用两个网络——生成器 (Generator) 和判别器 (Discriminator)——来提高生成图像的清晰度。给定视频的前四帧，生成器学习为下一帧生成准确的预测。给定生成的图像或真实世界的图像，判别器学习正确区分生成图像和真实图像。这两个网络相互“竞争”，生成器试图欺骗判别器，使其将输出分类为真实图像。这迫使生成器创建与领域内真实帧非常相似的帧。\n\n## 结果与对比\n我在 Ms. Pac-Man 的视频帧序列数据集上训练并测试了我的网络。为了比较对抗训练与非对抗训练，我分别在生成器和判别器上训练了对抗网络 500,000 步，并训练了非对抗网络 1,000,000 步（因为非对抗网络的运行速度大约快两倍）。每个网络的训练大约需要 24 小时，使用的是 GTX 980TI GPU。\n\n在以下示例中，我递归地运行网络生成了 64 帧。（即：生成第一帧的输入是 [input1, input2, input3, input4]，生成第二帧的输入是 [input2, input3, input4, generated1]，以此类推）。由于网络没有接收来自原始游戏的动作输入，它们无法预测大部分真实运动（例如 Ms. Pac-Man 将向哪个方向转弯）。因此，目标不是与真实图像 (Ground Truth) 完美对齐，而是保持对世界清晰且可能的表示。\n\n以下示例展示了非对抗网络变得模糊并失去精灵 (Sprites) 定义的速度有多快。对抗网络在一定程度上也表现出这种行为，但在整个序列中更好地保持了至少某些精灵的清晰表示：\n\n\u003Cimg src=\"https:\u002F\u002Foss.gittoolsai.com\u002Fimages\u002Fdyelax_Adversarial_Video_Generation_readme_f9584dc79d18.gif\" width=\"100%\" \u002F>\n\n此示例展示了对抗网络如何在多次转弯中保持 Ms. Pac-Man 的清晰表示，而非对抗网络则无法做到这一点：\n\n\u003Cimg src=\"https:\u002F\u002Foss.gittoolsai.com\u002Fimages\u002Fdyelax_Adversarial_Video_Generation_readme_0946cd52839d.gif\" width=\"100%\" \u002F>\n\n虽然对抗网络在清晰度和随时间的一致性方面明显优于非对抗网络，但非对抗网络确实生成了一些有趣\u002F壮观的失败案例：\n\n\u003Cimg src=\"https:\u002F\u002Foss.gittoolsai.com\u002Fimages\u002Fdyelax_Adversarial_Video_Generation_readme_3eeb340c8352.gif\" width=\"50%\" \u002F>\n\n使用论文中概述的误差测量（峰值信噪比 (Peak Signal to Noise Ratio) 和锐度差异 (Sharp Difference)）并未显示出对抗训练和非对抗训练之间的显著差异。我认为这是因为 Ms. Pac-Man 数据集中的连续帧在大多数像素上没有运动，而原始论文是在真实世界的视频上训练的，其中大部分帧都有运动。尽管如此，很明显对抗训练产生了生成帧清晰度的定性改进，特别是在长时间跨度上。你可以从该项目根目录运行 `tensorboard --logdir=.\u002FResults\u002FSummaries\u002F` 来查看损失和错误统计信息。\n\n## 使用方法\n\n1. 克隆或下载此仓库。\n2. 准备你的数据：\n  - 如果你想复现我的结果，可以 [在此处下载 Ms. Pac-Man 数据集](https:\u002F\u002Fdrive.google.com\u002Ffile\u002Fd\u002F0Byf787GZQ7KvV25xMWpWbV9LdUU\u002Fview?usp=sharing&resourcekey=0-Vequaxb8kl0m_NIzJJt52g)。将此文件放在项目根目录下的 `Data\u002F` 目录中以获得默认行为。否则，你将需要使用第 3 和第 4 部分概述的选项指定你的数据位置。\n  - 如果你想在自己的视频上训练，请预处理它们，使其成为如下结构的帧序列目录。（名称和图像扩展名无关紧要，只有结构重要）：\n  ```\n    - Test\n      - Video 1\n        - frame1.png\n        - frame2.png\n        - frame ...\n        - frameN.png\n      - Video ...\n      - Video N\n        - ...\n    - Train\n      - Video 1\n        - frame ...\n      - Video ...\n      - Video N\n        - frame ...\n  ```\n3. 处理训练数据：\n  - 网络在输入图像的随机 32x32 像素裁剪上进行训练，经过过滤以确保大多数片段包含一些运动。要将输入数据处理为此形式，请在 `Code\u002F` 目录下运行脚本 `python process_data` 并使用以下选项：\n  ```\n  -n\u002F--num_clips= \u003C# clips to process for training> (Default = 5000000)\n  -t\u002F--train_dir= \u003CDirectory of full training frames>\n  -c\u002F--clips_dir= \u003CSave directory for processed clips>\n                  (I suggest making this a hidden dir so the filesystem doesn't freeze\n                   with so many files.
