Sensibility-aware image retrieval methods are presented and their performances are compared. Three systems are discussed in this paper: PCA/ICA-based method called RIM (Retrieval-aware IMage format), JPEG, and JPEG2000. In each case, a query is an image per se. Similar images are retrieved to this query. The RIM method is judged to be the best settlement in(More)
Image-to-image retrieval (I2I) accompanied by data compression are presented. Given a query image, the presented retrieval system computes PCA and/or ICA bases by extracting source information. On the data compression in the sense of rate-distortion, this method outperforms JPEG which uses DCT. Besides, PCA and ICA bases reflect each imagepsilas edge and(More)
New methods for joint compression and Image-to-image retrieval (12I retrieval) are presented. The novelty exists in the usage of computationally learned image bases besides color distributions. The bases are obtained by the Principal Component Analysis and/or the Independent Component Analysis. On the image compression, PCA and ICA outperform the JPEG's DCT(More)
