One of features in JPEG2000 is ROI(region of interesting) coding technique.Since the shape of interesting region is manually optional

the influence of uninterested region could be very small.This paper presents a novel and efficient scheme for remote sensing image retrieval

which does not need to decode JPEG2000's code stream completely.It extracts the spectral features of objects based on the properties that objects could reflect different waves in different wave band.The subsequent retrieval is based on the spectral feature.Further more

a new measurement scheme designed by which similarity between two images is computed and then the retrieval is realized.The experimental results show that this method is accurate and efficient.In addition

it costs much less time than the traditional method.
