A new benchmark paper introduces thirteen methods for quantifying image mirror symmetry, comparing classical and deep learning approaches. The study found that deep learning models generally perform better on single-axis and complex multi-axis symmetry scoring. However, a classical Histogram of Oriented Gradients (HOG) descriptor showed competitive performance, running significantly faster than deep methods and offering comparable results to some frozen deep features.
