MixFormer: End-to-End Tracking with Iterative Mixed Attention[1]

作者是来自南大的Yutao Cui, Cheng Jiang, Limin Wang, Gangshan Wu. 论文引用[1]:Cui, Yutao et al. “MixFormer: End-to-End Tracking with Iterative Mixed Attention.” 2022 IEEE/CVF Conference on Computer Vision and Pattern Recognition (CVPR) (2022): 13598-13608.

Time

  • 2022.Mar

Key Words

  • compact tracking framework
  • unify the feature extraction and target integration solely with a transformer-based architecture

VOT,MOT,SOT的区别

  1. VOT是标首帧,MOT是多目标追踪,SOT是单目标追踪。

动机

  1. Tracking经常用多阶段的pipeline:feature extraction,target information integration,bounding box estimation。为了简化这个pipeline,作者提出了一个紧凑的tracking框架,名为MixFormer。

  2. target information integration解释: fuse the target and search region information

在Ubuntu 20.04里安装 Nvidia RTX 3060显卡的驱动

  1. 之前照着网上的教程弄过一次,记得是通过命令行来弄的,结果搞得黑屏,好不容易解决了黑屏的问题,进入桌面之后,显示不了Wifi和蓝牙,好像缺了很多东西,搞得很狂躁。这两天跑Tracking,大部分是Ubuntu环境下的,就趁这次机会重装一下系统,然后找个新的教程

  2. 找到了两个方式:

    • 通过 Ubuntu 自带的Software & updates里头的additional drivers里,能看到有 Nvidia的显卡驱动,勾一个合适的就行,很简单。。全程没有什么bug。。害得我上次弄了好久。
    • 去nvidia官网上下载驱动,名称一般是 Nvidia-Linux-xxx.run,运行的时候需要先禁用掉 nouveau,在哪个文件里加上: blacklist nouveau, options nouveau modeset=0,然后重启,看看lsmod一下,看看nouveau有没有被禁用掉。然后运行 .run文件,在运行.run文件的时候:提示可以用Ubuntu里 additional drivers来安装。

Masked Autoencoders with Saptial-Attention Dropout for Tracking Tasks[1]

作者是来自CityU、IDEA、Tecent AI Lab、CUHK(SZ)的 Qiangqiang Wu、Tianyu Yang、Ziquan Liu、Baoyuan Wu、Ying Shan、Antoni B.Chan. 论文引用[1]:Wu, Qiangqiang et al. “DropMAE: Masked Autoencoders with Spatial-Attention Dropout for Tracking Tasks.” 2023 IEEE/CVF Conference on Computer Vision and Pattern Recognition (CVPR) (2023): 14561-14571.

Time

  • 2023.Apr

Key Words

  • masked autoencoder
  • temporal matching-based
  • spatial-attention dropout

动机

  1. 将MAE应用到下游任务如: visual object tracking(VOT) and video object segmentation(VOS). 简单的扩展MAE是mask out frame patches in videos and reconstruct the frame pixels.然而作者发现这个会严重依赖于spatial cues, 当进行frame reconstruction的时候忽略temporal relations, 这个导致sub-optimal temporal matching representations for VOT and VOS.
