Aiming at higher desire of robust and veracity brought by increasing variety of remote sensing images, by analyzing the problem that the decrease of original date’s size and the loss of original information in the matrix’s decomposition exist in the arithmetic, based on Independent Component Analysis (ICA, Independent Component Analysis) change detection, an improved decompose method with Undecimated Discrete Wavelet Transform (UDWT, Undecimated Discrete Wavelet Transform) was proposed. For removing the influence of the noise to detection result, the segmentation method of object-oriented was used to get the image objects, and distilled the shape character of the image objects to replace the original images. Finally, the robust and veracity of proposed method has been proved through simulation.
