Because of the distortions produced by the reflection of a mirror
catadioptric omnidirectional images cannot be processed similarly to classical perspective images.In this paper
we propose to define a new model named omnidirectional total variation (Omni-TV)
which reflects the omnidirectional image structure features.In order to reconstruct the images from compressive samples
the Omni-TV is used as the subject function during the image reconstruction.The simulation results show that the omnidirectional images could be reconstructed effectively and accurately.Comparing with classical TV minimization model
the images
which are recovered based on Omni-TV model
can provide higher quality both in subjective evaluation and objective evaluation.
