With the advances of the artificial intelligence, content-based image retrieval can be developed as multi-level schemes with low-level and high-level features involved. In this talk, the functions and extended advantages of the digital halftoning will be introduced. An extremely low complexity compression scheme with the aid of digital halftoning is later presented. As most images are compressed and recorded, compressed domain features are thus intuitively adopted to form the low-level features for the image retrieval. Conversely, features generated by deep learning can better characterize human perception through various operations such as convolution and pooling, and thus achieve effective retrieval performance. At the end of this talk, the fusion descriptors from low- and high-level features will be introduced, and the hybrid image retrieval system will subsequently be demonstrated with practical examples.
