Color differences between different views can cause performance degradation in multiview video coding. In order to overcome this problem, in this paper a local color correction method based on histogram segmentation is proposed. In the proposed method, we correct the color changes in the different segmentation regions between the current picture and the reference picture. Extensive experimental results demonstrate that the proposed method outperforms the traditional global linear color correction methods with objective mean of disparity values and subjective visual quality, and achieves better correction results.

We demonstrate a highly efficient inverted top-emitting organic light-emitting diode (TOLED) having stable electroluminescent spectra and color coordination with variation of viewing angles by simply tuning the reso- nance wavelength corresponding to the free emission of the emitter. Using a doped fluorescent emitting system, the inverted TOLED exhibits an enhanced maximum current efficiency of 19 cd/A and a power efficiency of 17 lm/W, which are much higher than those (11 cd/A and 5 lm/W) of the counterpart with normal structure, although both TOLEDs behave with similar stable electroluminescent spectra characteristics. The results indicate that we provide a simple and effective method of constructing an excellent inverted TOLED for potentially practical applications.

We investigate the video transmission efficiency of channel code, modulation mode and layered space time code for region of interest video transmission system. Excellent channel code achieves more coding gains, suitable modulation mode adaptively overcomes different channel fading and layered space time code achieves not only coding gain but only diversity gain. Based on the above analysis, we propose an adaptive video transmission system according to channel environment and video constructed quality require. We derive an analytic bound for the error probability, and conduct experiments for H.264 interest of region video streaming. It is shown that the proposed system enhances the PSNR performance of region of interest significantly by adaptive choice of channel code, modulation mode, and layered space time code in the wireless channel.
