Rapid multi-modal image fusion method, system and device based on simplified adaptive parameter pulse coupling neural network, and medium

A fast multi-modal image fusion method, system and device based on a simplified adaptive parameter pulse coupling neural network and a medium, the method comprising: converting a color picture RGB channel into a YUV channel, normalizing a gray picture and a color picture Y channel, then using a Laplacian pyramid to decompose to obtain a high-pass sub-band and a low-pass sub-band, and using the high-pass sub-band and the low-pass sub-band to obtain a high-pass sub-band and a low-pass sub-band; the high-pass sub-bands are fused by using an SPAPCNN rule to obtain a high-frequency image, the low-pass sub-bands are fused by using an MN-DWRE rule to obtain a low-frequency image, the high-frequency image and the low-frequency image are subjected to inverse decomposition by using an inverse Laplacian pyramid to obtain a Y channel of a fused image, the Y channel of the fused image is combined with U and V channels of an original image, the combined image is converted into an RGB channel, and standardization processing
