摘要

The algorithm first extracts the brightness component Y in the YIQ color space, and enhances it with the Directed filter, and then superimpose them and convert them into grayscale images. finally, the wavelet transform is used to fuse the two images to obtain a new brightness component, which is fused with the I and Q components and then converted back to the RGB color space, so as to obtain an im...
