CONFERENCE PROCEEDINGS FREE ACCESSRecently viewers' desires have been shifted from high-resolution images to high-gradation images, and HDR (High Dynamic Range) images have been actively studied. In particular, because digital SLR (Single-Lens Reflex) cameras can easily acquire HDR data, HDR display is required in display devices. In this study, by performing multiple projection with four general-use projectors that have 256 gradations, we realize HDR display that has 1024 gradations. Then, we propose two types of response function for the HDR display. These functions are based on human vision. This paper reports what kind of response function is suitable for HDR display.View full abstractDownload PDF (786K) -

CONFERENCE PROCEEDINGS FREE ACCESSRecently, image projection has been becoming popular since projectors advance in miniaturization, low price and high brightness. For image projection on an arbitrary plane, luminance correction has been studied to remove influence of patterns on the plane from the projected image. However, changing a dynamic range of the projected image by the luminance correction causes changing impression of the projected image from that of the original image. In this study, by focusing on accepted clipping errors, we examine dynamic ranges of the projected image that make the impression of the projected image close to that of the original image.View full abstractDownload PDF (1140K) -

CONFERENCE PROCEEDINGS FREE ACCESSIn this article, a method is proposed to generate an icon corresponding to a given music which evokes an atmosphere of the music for easy understanding and/or selection of the music's category. The music is analyzed in Frequency domain to determine dominant pitch, sound volume, and proportion of low/high frequency components. The icon is generated so that these values are depicted on the vertical axis while playing time-line is adopted for horizontal axis. Several examples show that these icons feature characteristics of music.View full abstractDownload PDF (749K) -

CONFERENCE PROCEEDINGS FREE ACCESSIn this paper, we focus on gradation of colors as representing kansei information of images. We regard color distribution of an image as a cluster of gradation, and propose a method to convert the color information of images by evaluating the feature of gradation. We performed an experiment of kansei evaluation to confirm that the impression of image converted by gradation feature of an image becomes similar to the impression of another image. We consider that the impression of another image is reflected in the converted image as a result of the qualitative evaluation.View full abstractDownload PDF (969K) -

CONFERENCE PROCEEDINGS FREE ACCESSCamera images taken through window glass sometimes have a problem of reflection on the glass surface. This phenomenon is conspicuous in night scene. This paper proposes a method for separation of night scene and reflection using stereo vision. The method determines the area of the night scene using the fact that the disparity appears only in the reflection. Experimental results showed the effectiveness of the proposed method.View full abstractDownload PDF (924K) -

CONFERENCE PROCEEDINGS FREE ACCESSIn this paper, we propose a 3D measurement method of water tank surface and submerged objects by using a laser range finder (LRF) which consists of a camera and a spot light laser mounted on a manipulator. When applying our method to measure water tank surface and submerged objects, we meet with the problem of recognition of reflected light from water tank surface and submerged objects in an image. Therefore, we propose a method to recognize the reflected light. To recognize reflected light from water tank surface, the method uses LRF with variations of LRF posture. In addition, to recognize reflected light from submerged objects, the method uses distance between laser and camera ray in ray tracing. Experimental results show the effectiveness of our proposed method.View full abstractDownload PDF (832K) -

CONFERENCE PROCEEDINGS FREE ACCESSWe often see various types of fonts in advertising media or some package design. There are also many opportunities to select suitable fonts for presentation slides or website designs. However, existing font selection task becomes a hard task as the number of candidates increase, because we select the desired font while confirming the displayed fonts. This report proposes a novel font selection method using Interactive Genetic Algorithm and Similarity Search. This feature is to show some fonts depending on user's KANSEI including various types of fonts. Our method allows the users to select their desired font from many candidates easily.View full abstractDownload PDF (951K) -

CONFERENCE PROCEEDINGS FREE ACCESSSurrounding images can give an immersive feeling. However, surrounding image projection needs to construct special screens that surround audiences and to prepare a number of projectors for presenting surrounding images on the screens. Consequently, it is difficult to enjoy surrounding images at home. In this study, we use walls of an indoor space as surrounding screens, and to project surrounding images with two projectors, we expand the projected planes by placing a fish-eye lens in front of each of the projectors.View full abstractDownload PDF (1868K) -

CONFERENCE PROCEEDINGS FREE ACCESSToday, audio systems that provide a voice-guided navigation and background music for the ornamental objects and events have been implemented in the field of museum, theater and others. These systems present augmented reality (AR) by appending auditory information related to them in the real world. However, the study for auditory AR techniques is a few compared with visual AR techniques. In this paper, we studied a volume control method for auditory AR system that clearly presents directions of several sound sources to listeners.View full abstractDownload PDF (719K) -

CONFERENCE PROCEEDINGS FREE ACCESSContent creators have to consider the large number of pattern of camera paths and emotional effects for setting the camera work on the CG scene. This task requires content creators to technical experience, and will be a burden on them. Therefore, the technology for automatically controlling appropriate camera work has been conducted. This study is a fundamentally investigation into automatic generation of appropriate camera works on CG scene. In this paper, we explained that invented CG system consisting of particle (random dot) to evaluate the camera works, and conducted subjective evaluation experiment.View full abstractDownload PDF (896K) -
