To enable interoperability in the context of deep feature coding, standardization is urgent and important. ...
However, due to the explosion of deep learning algorithms and the particularity of feature coding, there are numerous remaining problems in the standardization process. ...
More specifically, the local descriptors consist of SIFT descriptors which are efficiently compressed by a low-complexity transform coding. ...

For mobile visual-search systems that transmit or locally store image features, more compact descriptors are needed. The compressed histogram of gradients (CHoG) descriptor 7 offers one such design. ...
First, local features (or descriptors) are extracted from the query image. The set of local features is used to assess the similarity between query and database images. ...
