Fast JPEG encoding for color fax using HVQ

Ricardo L. de Queiroz, Patrick Fleckenstein, Bhaskaran Vasudev, T. Russell Hsing, Andrew G. Tescher, Robert L. Stevenson

We derive a JPEG compliant image compressor which is based on hierarchical vector quantization (HVQ). The goal is to reduce complexity while increasing compression speed.  ...  For each block, the DCT DC coefficient is encoded in the regular way while the residual is mapped through HVQ to a pre-computed bit-stream corresponding to the compressed DCT AC coefficients.  ...  For large compression ratios, artifacts caused by HVQ mapping start to be masked by the artifacts caused by the scalar quantization in JPEG.  ...

Beyond Bag of Words for Concept Detection and Search of Cultural Heritage Archives [chapter]

Differently from common techniques based on the Bag of Words model, our solution does not rely on the construction of a visual vocabulary, thus removing the dependence of the image descriptors on the specific  ...  Typically a Bag of Words approach is followed, where a codebook is built by quantizing the local features.  ...  Conclusions In this paper we propose a novel approach for image retrieval and automatic annotation of cultural heritage images.  ...
