In this paper, a new adaptive multi-thretholding image denoising method based on the decomposition order is presented, which is built upon the ideas of Embedded Zero tree Wavelet (EZW) encoder and separate character of signals and noises. This method is not increase in operation amounts but excellent in image denoising results.
A compression quality prediction model is proposed for grey images coding with JPEG2000. With this model, the compression quality (PSNR) could be estimated according to the given compression ratio (CR) and the image activity measures (IAM) without coding images. The image activity measure is the weighted sum of the IAM values based on the 1-pixel-distance and 2-pixel-distance gradients along horizontal...
With the digital technology developments, Digital Cinema outperforms traditional films and attracts the movie industry. The first edition Digital Cinema System Specification was released by Digital Cinema Initiatives, LLC (DCI) in 2005, which advances the Digital Cinema development. We have developed a Digital Cinema Playback system compliant with the DCI Specification. It can extract and play the...
