Optimized hierarchical block matching for fast and accurate image registration
作者：
Highlights：
• We propose a novel optimized hierarchical block matching algorithm.
• We determine an optimal image pyramid minimizing the computational cost.
• The search window is properly determined to resolve possible error propagation.
• We propose a simple but effective method for aligning colors between two images.
• The experimental results show that the methods increase the speed and accuracy.
