Abstract:

Non-subsample shearlet transform (NSST) is suggested into the multi-focus image fusion, for its advantage in image fusion and the feature of multi-focus imaging. Orientation information measurement can highlight the edge texture characteristic and reduce the noise, so it is used in the fusion of high-frequency coefficients. Therefore, the fusion image is brought out after the NSST inverse transformation is taken on the fusion of low-frequency and high-frequency coefficients. Simulation is carried out to prove the effectiveness and practicability the proposed technique, which illustrates that the proposed method can improve the quality of fusion images and increase the information of fusion images, meanwhile, the noise of images is also decreased.
