Center node: "person re identification by contour sketch under moderate clothing change"
  Abstract: The majority of existing models of person re-identification(re-id) that matches pedestrian images across different camera views are largely dependent on color appearance. However, this can be an issue if that person changes his/her clothes, causing most existing methods to fail. We call person re-id under clothing change the "cross-clothes person re-id". Particularly, as a first attempt at solving this problem using visible light images, we assume a person only changes his/her clothes moderately when the weather doesn't change substantially within a short period so that the shape of a person would not change significantly. We perform cross-clothes person re-id based on a contour sketch of person image to take advantage of the shape of human body instead of color information. To select more discriminative curve patterns on a body contour sketch, we introduce a learning-based spatial polar transformation(SPT) layer in convolutional neural network(CNN) to transform contour sketch images into a polar coordinate space. An angle-specific extractor(ASE) is applied in the CNN to extract more fine-grained discriminant angle-specific features. Finally, we develop a multistream network for aggregating multi-granularity features. We also contribute a cross-clothes dataset consisting of 33698 images from 221 identities. Our experiments demonstrate the effectiveness of our proposed method.
