Embodiment Construction
[0030] The embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. This embodiment is carried out on the premise of the technical solution of the present invention, such as figure 1As shown, the detailed implementation and specific operation steps are as follows:
[0031] Step 1, use SIST transformation to decompose the two multi-focus images to be fused, and obtain low-frequency subbands after image decomposition and high frequency subband Among them, "maxflat" is selected for the scale decomposition LP, "pmaxflat" is selected for the direction filter bank, and the direction decomposition parameter is set to [3,4,5];
[0032] Step 2, low-frequency sub-band coefficient fusion and high-frequency sub-band coefficient fusion:
[0033] 1) For low frequency subband coefficients Using the average fusion strategy:
[0034]
[0035] in, and Respectively represent the corresponding low-frequency coefficients of...
