Histogram-based image retrieval using Gauss mixture vector quantization

  title={Histogram-based image retrieval using Gauss mixture vector quantization},
  author={Sangoh Jeong and Chee Sun Won and Robert M. Gray},
Histogram-based image retrieval requires some form of quantization since the raw color images result in large dimensionality in the histogram representation. Simple uniform quantization disregards the spatial information among pixels in making histograms. Since traditional vector quantization (VQ) with squared-error distortion employs only the first moment, it neglects the relationship among vectors. We propose Gauss mixture vector quantization (GMVQ) as the quantization method for a histogram… CONTINUE READING
