Embodiment Construction
[0036] The embodiments and effects of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0037] refer to figure 1 , the present invention is based on the multi-focus image fusion method of directional filter (and deconvolution neural network), and the realization steps include as follows:
[0038] Step 1, design an initial high-pass directional filter and an initial Gaussian low-pass filter.
[0039] The high-pass directional filter has the function of accurately extracting the detailed information of the image in the corresponding direction, and the Gaussian low-pass has the function of smoothing the image and filtering noise. Their design methods are as follows:
[0040] (1.1) The design size is N, and the cutoff frequency is δ 1 The initial Gaussian low-pass filter:
[0041] According to the two-dimensional Gaussian function: The cutoff frequency is obtained as δ 1 The calculation formula of is as follows:
[0042...
