In Digital Terrestrial Television Broadcasting (DTTB), delay profile is measured from Scattered Pilot signals. But, direct current component remains behind in delay profile by attered Pilot signals including desired wave component. Therefore it is difficult to measure an existing multi-path component near a desired wave. This paper propose the method to reduce the direct current component from Delay profile. Delay profile calculated by Proposed Method can measure an existing multi-path near a desired wave.

We conducted the research of the improvement by the 4-diversity reception in the poor reception areas of terrestrial digital broadcast, and its effectiveness was confirmed. As a result, it is possible to view by high definitions relatively easily in poor reception areas and we promote measures for this problem.

We have developed a novel compensation method of fast fading for ATSC Digital Television System. This paper describes the channel estimation technique by using known sequences and tentative decisions. By computer simulation, we show that our proposed method can improve performance in fast fading environments compared to the conventional method.

A prototype system for inferring TV scenes in which viewers show strong interest attempts to recognize viewers' facial expressions and combines the results with those from other modalities. An experiment demonstrated that our facial expression recognition method could recognize a certain expressive face with great accuracy.

To develop emotional speech synthesis technology for sound broadcasting services, listening test judging emotion of speech data was conducted. The results show that about 300 data can be available to formulate the rule of controlling emotional characteristics of speech by extracting the data with more than 70% answered correctly.

Directional intra prediction currently used in H.264/AVC and H.265/HEVC is unsuitable for curved textures because predicted values are always extrapolated along straight lines in a given direction. In this paper, we propose a new prediction technique which enables interpolative prediction along circular curves defined by two kinds of parameters.

We previously proposed a block-based adaptive prediction method for efficient coding of color video signals in RGB 4:4:4 format. The method exploits temporal, spatial and inter-color correlations of color video signals simultaneously. In this paper, we extend the temporal prediction to use multiple reference frames in a similar way to the variable block size bi-prediction.

I describe the process of removing unwanted object of image editing technology by computer. Removed using a three-dimensional viewpoint intermediate image which generated by performing averaging the pixel values and coordinates from of two image to the unwanted object area .Middle picture quality generated by the former is made clearer this time, and the research which generated few complement pictures of sense of incongruity is reported.

Application of compressed sensing (CS) to MR multi-slice imaging was examined with reference to 2D- and 3D-MR imaging. Simulation experiments showed that obtained images in multi-slice CS have a better resolution and contrast compared to those obtained in 2D-CS using signals having the same reduction factor.

We Propose a method for transforming a given pixel art into another pixel art which is composed of round pixels, by using which, we can suppress jagged edgeds in pixel art. Experimental results show that the proposed method suppresses jagged edges while keeping the appearance of contents better than conventional morphological method.
