Template Interactive Matching Based on Wavelet Pyramid

Haar wavelet transform can be utilized in image registration to facilitate template interactive matching using wavelet pyramid decomposition, which enables multi-resolution analysis for improved matching efficiency.

Wavelet Transform for Each Image Channel

Perform wavelet transformation on each image channel to obtain horizontal, vertical, and 45-degree diagonal high-frequency components along with low-frequency components, constructing wavelet pyramids for individual channels. Fuse corresponding feature maps from different pyramid levels of both images using a maximum-value selection principle. Finally, reconstruct the fused image through inverse wavelet transformation based on the combined wavelet coefficients.
