— In this paper, we are interested in studying the impact of the compression on the performances of some wavelet-based retrieval systems. Firstly, we show that the quantization operation of JPEG2000 has a negative effect on the performance of these content-based image retrieval systems for a given feature extraction method. Moreover, in this work, we aim at(More)
With the great demand for storing and transmitting images as well as their managing, the retrieval of compressed images is a field of intensive research. While most of the works have been devoted to the case of losslessly encoded images (by extracting features from the unquantized transform coefficients), new studies have shown that lossy compression has a(More)
