Embodiment Construction
[0091] The present invention will be described in detail below in combination with specific embodiments.
[0092] The present invention provides a fusion method of infrared and visible light images based on spectral wavelet transform, which performs spectral wavelet decomposition on infrared images and visible light images according to the four-layer decomposition scale to obtain low-frequency sub-band coefficients and high-frequency sub-band coefficients. The obtained low-frequency sub-band coefficients are fused with high-frequency sub-band coefficients on different decomposition scales, and spectrogram wavelet inverse transform is performed on the fused low-frequency sub-band coefficients and high-frequency sub-band coefficients to obtain a fused image.
[0093] An embodiment of the present invention provides an infrared and visible light image fusion method based on spectral wavelet transform, such as figure 1 As shown, it is realized by the following steps:
