Abstract: Content based image retrieval is grievous need of present scenario in digital imaging world. This work presents a new multi-scale content based image retrieval system which leverages the multi-resolution property of discrete wavelet transform (DWT) and the local information attribute of local extrema patterns (LEPs). Two level DWT is applied on images and wavelet coefficients are obtained for images, further the LEPs are collected from wavelet coefficients to extract the feature vector. The proposed method abbreviated as DWT+LEP and tested on two benchmark databases for validation and compared with local extrema patterns (LEPs), discrete wavelet transform (DWT), center-symmetric local binary pattern (CS LBP), local edge pattern for image retrieval (LEPINV), local edge pattern for segmentation (LEPSEG), local binary pattern (LBP) and block based local binary pattern (BLK LBP). © 2014 IEEE.
