Interrupted sampling repeater jamming (ISRJ) is a novel intra-pulse coherent based on digital radio frequency memory (DRFM). By repeatedly and retransmitting the radar transmitting signal fragments, series of false targets can be formed after pulse compression (PC), posing severe threat to modern systems. Inspired by energy function method histogram analysis in image processing, an adaptive tim...

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 ve...
