SIMILARITY AND RIGIDITY PRESERVING IMAGE RETARGETING

Conventional Image Retargeting methods aim to preserve the salient regions in an image using As Similar as Possible (ASAP) energy formulation or As Rigid as Possible (ARAP) energy formulation. ASAP energy formulation preserves the shape of the salient object while the scale of salient object can get distorted in the retargeted image. On the contrary, ARAP energy formulation preserves the scale of the salient object while the shape can get compromised. We propose a novel technique in which the necessity to preserve similarity and rigidity of the salient object is taken into consideration in a single energy formulation. The concept of object centric saliency is also introduced to improve the quality of image retargeting. The subjective and objective results on retargetMe database demonstrate the advantage of the proposed method than using ASAP or ARAP energy alone.
