Fusion of infrared and visible images based on target segmentation and compressed sensing
The image fusion of infrared and visible light is susceptible to noise and the target information is weakened easily. Therefore, a new fusion algorithm based on target area extraction and compressed sensing was proposed. Firstly, the infrared image was detected in a salient region at frequency-tuned domain to obtain a corresponding salient map. Under the guidance of the salient map, the infrared target area was extracted together with region growing method to effectively overcome the effects of noise and complex background interference on target segmentation. Then, non-subsampled shearlet transform was adopted to decompose the source images and the high and low frequency sub bands in the target and backgound regions were fused respectively. Finally, a new fusion rule was proposed based on multi-resolution singular value decomposition and compressed sensing, and the fused image was reconstructed by the non-subsampled shearlet inverse transform. As compared with the other algorithms, experimental results show that the algorithm highlights the target area, preserves the details of the source images and suppresses the noise interference. The image fusion quality evaluation indexes including information entropy, standard deviation, mutual information and transferred edge information have increased by 3.94%, 19.14%, 9.96% and 8.52%, respectively.
