For solving the problems of the complexity about feature extraction on largesize image and the loss of feature information
the characteristics of compressive sensing (CS) theory that a small amount of measurements can accurately reconstruct the original signal is used
and a new image retrieval method based on compressive sensing is proposed. First
the wavelet transformation is performed
and the image is divided into blocks. Then
blocked polynomial deterministic measurement matrix and conduct fast CS measurement on blocked image constructed
and very few compressive measurements which represent the image features can be obtained. Finally
we calculate the similarity between the measurement features by weight distance is calculated
so to implement accurate image retrieval. At the same time
it is proved theoretically that the blocked polynomial deterministic measurement matrix is satisfied to the restricted isometric property (RIP). Experimental results show that this method has higher performance on image precision and image recall
and can be applied to massive complex image retrieval.
