We previously proposed a lossy image coding scheme based on recursive-type intra prediction
which can use both local and non-local reference pels at the same time. In this paper, we extend the prediction
technique to make use of multiple non-local pels collected by template matching. To reduce side information
on prediction coefficients, a weighted average of the non-local pels is used as the reference one.

The 4K/8K BS trial broadcasting will start from August 2016. The BS has so wide bandwidth that it can transmit 4K HEVC with 44Mbps. A cable network restricts the bandwidth to 29Mbps/38Mbps by the 64/256QAM specification. In this manuscript, a BS 4K transcoding performance is reported for the feasibility study of a retransmission over the cable network.

It becomes often difficult to grasp controllers in the real space through the VR-HMD. However, it would lose interest to go back and forth between the real world and a virtual world, and damage immersive presence. We propose a simple method for acquiring the information of the real space through the VR-HMD.

We present an iterative method for refining weave patterns in color tape weaving images by minimizing errors
between input colors and weaved images smoothed with a cross bilateral filter. Color palettes are adaptively derived from
each input image and they are set to the color of tapes. A procedure for restricting floating tape length is incorporated into
this weaving method for ensuring mechanical strength of weaved tapes.

Technologies to segment videos into “scene” units consisting of the shot sequence captured in a same place have been useful for program video retrieval and video summarization. We proposed scene segmentation methods based on the change of color formation produced from color histogram , and the change of block-image-kinds formation considering not only color but also textural properties. However, these methods have problems that slight color noises and drastic changes of camera angle could cause false positives. In this paper, we report on our new proposal method of scene segmentation adopting the color formation based on “superpixel” as an unit of image segmentation to solve problems in our conventional methods.

The spatial property of video signals is different from their temporal property. If the 3-D DFT is applied to video
signals, mainly phases of specific DFT coefficients will be affected by apparent motions of moving objects. On the other hand,
the 3-D DCT is equivalent to the following transform, that is to say, video signals are first converted into even-symmetric
signals about the origin, and then the symmetric signals undergo 3-D frequency analysis. Object’s motion produces many
significant 3-D DCT coefficients. Obviously, the 3-D DFT is superior to the 3-D DCT in energy compaction. This paper shows
the superiority of the 3-D DFT over the 3-D DCT, through theoretical analysis and experimental simulations.
