... optimal solution that minimizes the transmission energy cost while meeting certain distortion constraints. Since the operational energy-distortion function E(D(S ∗ (λ))) is monotonic with respect ... around 300 times. This demonstrates that video summarization is indeed an effective energy conservation scheme for wireless video streaming applications. 5. CONCLUSION AND FUTURE WORK In this...

Not only does an additional video provide nonverbal cues on the confidence ... projection. The rea- son for this is that when a person acts in front of the board and a front projector is used, the board content is also projected onto the person. This makes segmentatio...

Observe that the reconstruction error i s also a function of the upsampling ... explanation, we will here consider an LP with only one level of decomposition. For multiple levels of decompositions, the results can be de- rived by repeating the operations on the...
