Multi-Fiber Networks for Video Recognition

This repository contains the code and trained models of:

Yunpeng Chen, Yannis Kalantidis, Jianshu Li, Shuicheng Yan, Jiashi Feng. "Multi-Fiber Networks for Video Recognition" (PDF).


We use MXNet @92053bd for image classification and PyTorch [email protected] for video classification.


The inputs are substrated by mean RGB = [ 124, 117, 104 ], and then multiplied by 0.0167.


Train motion from scratch:


Fine-tune with pre-trained model:




Evaluate the trained model:

cd test
# the default setting is to test trained model on ucf-101 (split1)

Do I need to convert the raw videos to specific format?

  • Our `dataiter' supports reading from raw videos and can tolerate corrupted videos.

How can I make the training faster?

  • Decoding frames from compressed videos consumes quite a lot CPU resources which is the bottleneck for the speed. You can try to convert the downloaded videos to other format or reduce the quality of the video. For example:
# convet to sort_edge_length = 360
ffmpeg -y -i ${SRC_VID} -c:v mpeg4 -filter:v "scale=min(iw\,(360*iw)/min(iw\,ih)):-1" -b:v 640k -an ${DST_VID}
# or, convet to sort_edge_length = 256
ffmpeg -y -i ${SRC_VID} -c:v mpeg4 -filter:v "scale=min(iw\,(256*iw)/min(iw\,ih)):-1" -b:v 512k -an ${DST_VID}
# or, convet to sort_edge_length = 160
ffmpeg -y -i ${SRC_VID} -c:v mpeg4 -filter:v "scale=min(iw\,(160*iw)/min(iw\,ih)):-1" -b:v 240k -an ${DST_VID}
  • Find another computer with better CPU.
  • The group convolution may not be well optimized.
