The article proposes a one-step image retargeting algorithm using harmonic energy minimization to preserve regions of interest and line structures. It discusses cropping-based and mesh-based methods, highlighting the importance of conformal mapping for geometric distortion control. The algorithm involves simplicial approximation and bijection correction to ensure orientation preservation. Mathematical modeling and conformal energy calculations are detailed.
