Query: Wireless Transmission of Images With The Assistance of Multi-level
  Semantic Information   Semantic-oriented communication has been considered as a promising to boost
the bandwidth efficiency by only transmitting the semantics of the data. In
this paper, we propose a multi-level semantic aware communication system for
wireless image transmission, named MLSC-image, which is based on the deep
learning techniques and trained in an end to end manner. In particular, the
proposed model includes a multilevel semantic feature extractor, that extracts
both the highlevel semantic information, such as the text semantics and the
segmentation semantics, and the low-level semantic information, such as local
spatial details of the images. We employ a pretrained image caption to capture
the text semantics and a pretrained image segmentation model to obtain the
segmentation semantics. These high-level and low-level semantic features are
then combined and encoded by a joint semantic and channel encoder into symbols
to transmit over the physical channel. The numerical results validate the
effectiveness and efficiency of the proposed semantic communication system,
especially under the limited bandwidth condition, which indicates the
advantages of the high-level semantics in the compression of images.
