    In additive color mixture, n( 2 ≤ n ) colors are given then the color mixture result is determined uniquely. On the other hand, in subtractive color mixture, the result is not unique which are not clarified also in today. For the approach to the problem, we first derived theorems related to the upper and lower bounds of the subtractive color mixture. Second, using these theorems, theorems related to the centroid of the possible range of a stimulus value are derived. Because of the non-uniqueness of the results of subtractive color mixture, the centroid is very important. In this article, the discussions proceeds along a axis in the three dimensional( X,Y,Z ) space for simplicity.

  • Motion-Blurred Image Restoration based on Intensity Modulation/Demodulation
    Keisuke MUTA, Kazuki NISHI

    We propose a new image processing method for recovering the target image from the blurred version caused by the camera swinging or the target object motion. The moving target image is modulated by diffusion signals such as a chirp signal or a M-sequence, then the diffused image can be restored without attenuation of the high frequency components and amplification of noise through the demodulation operation. Simulation results show that the proposed method is greatly superior to the conventional Wiener filter.

  • Lossless Progressive Image Transmission via Bitplanes of Accumulated Pixel Values

    The present authors, in ealier articles, reported a lossless, progressive coding method of an image, in which multi-level error diffused images are reproduced progressively. A refined and generalized method is proposed, in which reproduced images have continuous tone. It is also showen that similar image reproduction is possible at eary stage. In this case, each pixel at early stage has larger error, and yet images are showen to be recovered with reasonable quality with the aid of interpolation of bitplane values. Characteristics of the revised coding scheme are reported, with attention on the behaviors at early stages.

    In this paper, we present a transmitting process of Holographic 3D movies adopted network?streaming technique and the hologram in which 3D objects are recorded as fringe patterns. Applying this method, an excellent transmission is shown to be achieved for Holographic 3D movies. Moreover, a good reconstruction of holographic images can be performed by utilizing transmitted streaming data. From this result, it seems to be possible to develop a new transmitting process of 3D moving data and stereo audio applying well-known conventional techniques in this field.

    The NetAIBO project aims to establish a new concept of communication over the Internet, getting a feel of existence in the virtual world by interacting with an actual robot "AIBO".Here we propose The unsimultaneous-communication and 3Dspace-sharing system with using web3d techniques and AIBO as interface.
