Motion-Compensated Orthogonal Video Transforms

Abstract:
In 1989, Torbjorn Kronander observed that techniques known at that time for 3D subband coding of image sequences do not use motion compensation. Knowing the importance of motion compensation for efficient video coding, he proposed a method for invertible motion fields. Unfortunately, motion compensation is, in general, not invertible and subsequent research addressed the problem of motion-compensated subband coding.In this talk, we review the basic concepts of video compression, stress advantages and disadvantages of popular compression schemes, and present a new class of motion-compensated orthogonal video transforms. This class offers strictly orthonormal subbands while permitting general motion compensation.Bio:
