Automatically erase objects in the video, such as logo, text, etc.

Overview

Video-Auto-Wipe

Read English Introduction:Here

  本人不定期的基于生成技术制作一些好玩有趣的算法模型,这次带来的作品是“视频擦除”方向的应用模型,它实现的功能是自动感知到视频中我们不想看见的部分(譬如广告、水印、字幕、图标等等)然后进行擦除。由于图标擦除模型存在潜在的被利用于侵权行为的隐患,因此我暂时只分享了字幕擦除模型,希望能帮助到大家。
  我后续会持续不断的探索和制作新的生成方向的技术内容。基于生成模型可玩的点还有很多,此项目仅展示了其中一个做落地应用的例子。本项目的模型版权所属为:www.seeprettyface.com ,未获得授权请不要直接用作商业用途。关于算法的细节介绍可以参阅我的研究笔记



效果预览

1. 图标擦除

  图标擦除模型的功能是模型自动感知到视频中图标的位置然后进行擦除,感知图标的方法为在时域上静止不动的小块像素块被视作图标。

2. 动态图标擦除

  动态图标擦除模型的功能是模型自动感知到视频中动态图标的位置然后进行擦除,感知动态图标的方法为在时域上闪烁出现或动态移动的固定像素块被视作动态图标,这个在制作上有一定难度所以还没有对外开放。

训练方法

训练数据

  1.YoutubeVOS2018数据集;

  2.基于搜集的300余部高清电影制作了2,709部电影片段数据集;
    下载地址:https://pan.baidu.com/s/1CIgJmFmx5iR2JfgAyjVaeg 提取码:xb7o

  3.基于搜集的40余部综艺节目制作了864部综艺片段数据集;

训练过程

  第1步. 针对特定任务的时域感知训练;
  第2步. 融合擦除模型的微调训练。

训练配置

最近寻觅到了一种非常简易的制作和训练方法:
  '图标擦除'模型在单卡3090上训练3天;
  '字幕擦除'模型在单卡3090上训练2天;





更多玩法

  这个项目目前还只是做了很短期的尝试,实际上视频擦除可玩的点还有很多,譬如敏感内容(涉黄涉暴等)擦除、广告擦除、指定人/物擦除、背景人擦除等等。只要是能寻找到有像素预测的场景+有像素预测的需求都是“视频擦除”可以玩出花样的情景~

Sample





了解更多

  本人的研究方向是生成模型的应用技术研究。生成技术解决的问题是像素的预测,也就是在一个有缺失/完全缺失的图像棋盘上进行像素的填补/预测,使填补/预测完的图像符合真实图像的规律。基于这种模式可展开的玩法有很多,除了我之前做的数字人生成、视频内容生成等,我们还可以拓展出更多并行的思路出来。
  尽管目前大部分的CV落地项目都集中在感知和识别任务上,而对于重构和生成任务的研发相对较少,但这不应影响我们对于生成技术价值的判断,毕竟生成技术是相对较新、参与人较少,但是应用前景较广的研究方向。我后续将持续致力于探索生成方向的落地型算法研发,欢迎访问我的网站了解这方面最新的研究进展:www.seeprettyface.com
