Query: Scale Coding Bag of Deep Features for Human Attribute and Action
  Recognition   Most approaches to human attribute and action recognition in still images are
based on image representation in which multi-scale local features are pooled
across scale into a single, scale-invariant encoding. Both in bag-of-words and
the recently popular representations based on convolutional neural networks,
local features are computed at multiple scales. However, these multi-scale
convolutional features are pooled into a single scale-invariant representation.
We argue that entirely scale-invariant image representations are sub-optimal
and investigate approaches to scale coding within a Bag of Deep Features
framework.
  Our approach encodes multi-scale information explicitly during the image
encoding stage. We propose two strategies to encode multi-scale information
explicitly in the final image representation. We validate our two scale coding
techniques on five datasets: Willow, PASCAL VOC 2010, PASCAL VOC 2012,
Stanford-40 and Human Attributes (HAT-27). On all datasets, the proposed scale
coding approaches outperform both the scale-invariant method and the standard
deep features of the same network. Further, combining our scale coding
approaches with standard deep features leads to consistent improvement over the
state-of-the-art.
