There is growing interest in imaging and display of stereoscopic images on a mobile phone. Mobile phone users can capture a stereo image pair by taking two pictures, one after another, with a single camera at the left and right eye positions. Such a handheld setup makes it difficult to take the stereo image pair at the exact positions. In this respect,(More)
In the video coding, the most significant problem is the encoding complexity. It is the distributed video coding (DVC) that the encoding complexity is decreased but the decoding complexity is increased. In the DVC, the encoding complexity is decreased by using the channel coding. Especially, LDPC(A) codes are widely used. In this paper, we introduce a new(More)
EZW, a wavelet transformation based compression algorithm, utilizes the correlations of the wavelet coefficients between subbands. Due to the reason that, it is based on Zero Tree’s parent-descendant dependency of the subbands, subband coding is possible, but it is not efficient for applications, which require multiresolution restorations. In this paper we(More)
We propose a multi-color cholesteric liquid crystal (CLC) film in a single-layered configuration with reactive mesogen (RM). The cholesteric pitches are controlled by temperature and memorized by photo-polymerization of the RM. Using the multi-pitch stabilization in a single layer, multicolor CLC display was obtained without any additional components.
