Embodiment Construction
[0023] A method for fusion of visible light and infrared images based on structural group double-sparse learning, comprising the following steps:
[0024] S1: Carry out sliding window processing on the input visible light and infrared images, find similar image blocks of the original image blocks, perform group vectorization on the original image blocks and similar image blocks, and establish an image similar structure group matrix;
[0025] S11: Using the sliding window technology, the size of the sliding window is n×n, and the sliding step is 1 pixel, and the visible light image V and the infrared image I of size M×N are divided into (M-n+1)·(N-n +1) image blocks.
[0026] S12: For each original image block p i , in the neighborhood of L×L, using the Euclidean distance as the measurement criterion, calculate the relationship with p i The most similar s image blocks, and the original image block p i Form a similarity group g with s similar image blocks i , there are s+1 i...
