Homographic p-norms: Metrics of homographic image transformation
作者：
Highlights：
• We propose homographic p-norms, metrics of homographic image transformation.
• We show that homographic p-norms satisfy metric properties.
• For use of the metrics, we provide several homographic 2-norm expressions.
• We compare their approximation errors, and validate the efficacy of the metrics.
• The metrics can be applied to various image processing and analysis tasks.
