A user of a photo-retouching software, such as Adobe Photoshop, can make painterly images. However, it is difficult for general user to reflect his/her expression based on a KANSEI information, into an image. In this paper, we propose a novel method, which allows converting a coloration in a painterly image by specifying an imaginary word.

HCP chart is a hierarchical program logic description method developed by NTT. In this chart, data structures, program constructions and their relations are graphically depicted. Thus, it is easier to understand than so called "flow chart". There are some script-based systems to build this chart. However, since compilation process is required to complete the chart, it is somewhat difficult to use. In this article, a Flash based HCP chart editing system is proposed. The system is an WYSWYG editor to build up HCP chart. Since original handwriting fashion is realized and building process is intuitively understandable, it is easier to depict than conventional methods, providing more neat chart.

In this study, we focused on evaluating business management by using the qualitative evaluation that cannot be determined from the corporation achievement value. We conducted feature analysis from consciousness gap between Manager and Employee. And we are conducting an investigation about the characteristic features that can lead a company to long existence and corporate growth.

Moving Objects Extraction in video is an essential technique for the high-end video coding such as object-based coding and/or video editing and video creating. There are some basic algorithms depending on requirement of extraction accuracy or processing volume, for example, the possibility of real-time processing. But, the optimal algorithm does not seem to be established in the present stage. In this report, the following Moving Objects Extraction approaches are investigated with some experimental results by the author et al., (1) region merging based on the motion model, (2) Watershed algorithm combined with active counter model, (3) Level Set Method.

This paper describes a new way of playing music by using motion tracking with Wii MotionPlus^<TM> and sensor accelerator, by a person. The results of motion detection produce sound and make him/her be able to play a song by following the various movements like in a musical score. The gestures to be reproduced are projected in front of him/her, by using a video projector. The detection of Wii Remote accelerations and Euler angles will produce sound effects like volume variation.

Noises in a vehicle have been decreased by recent advances of noise reduction technologies. But it could cost a lot more to reduce much more noises. It is, therefore, required that sounds in a vehicle are not only decreased but also created as sounds having comfortable feelings. In the present study, as a first step, we carried out subjective evaluation experiments of sounds in a vehicle while driving and describe findings.

In this study, we estimate driver's posture from a single camera video for analyzing relationship between driver's behaviors and traffic accidents. In this paper, we aim at realizing robust posture estimation of upper human body while driving. For the posture estimation, specific body parts such as a head, hands, shoulders are detected and sequentially tracked by using Particle Filter and HOG feature based recognition method. The proposed method actually applied to videos captured by a drive recorder, and the results shows effectiveness of the system.

It is important that we know how the human visual system perceives the real visual world in order to design novel visual communication systems and/or display devices. First, this paper describes examples of image quality evaluation; (1) an image quality evaluation method with multiple impairments based on visually weighted errors, and (2) quality evaluation of locally impaired images. Next, examples of applied human visual system associated with three-dimensional (3-D) perception are described; (1) a phenomenon that makes the human observer perceive depth incorrectly when an object occluded by the frame is displayed this side of the display plane and a technique called "virtual frame" that suppresses this phenomenon, and (2) a novel method called "depth-fused 3-D display (DFD)" that enables a human observer to perceive an apparent 3-D image using only two intensity modulated 2-D images at different depths.

It is difficult for non-experts to set up a proper camera path in 3-dimendional computer graphics space. Also, it is thought that viewer's environments change the proper camerawork. In this paper, we study the relation between camera path and screen size, and search parameters that are useful for automatic generation of camerawork. This study is a fundamental investigation for developing technologies that automatically control the camerawork adapted to various screen sizes.

We previously proposed a study of spatial scalable coding method based on seam carving. The conventional method saved all of seam position information. However, it was the cause of inefficient coding. In this paper, we propose the information amount reduction method for a study of spatial scalable coding method based on seam carving. Experimental result shows that the proposed method can reduce the amount of information.

Shape From Focus/Defocus (SFF/SFD) has been known as a depth estimation technique by using focus information. The technique estimates the depth for each point of a target object based on a focus measure extracted for each block on a set of multi-focus images. The authors have proposed a 3-D whole shape reconstruction technique, which first obtains a set of multi-view and multi-focus images for a target object and then integrates a set of shape models from each viewpoint by the SFF/SFD. In this technique, however, the SFF/SFD is applied to a single set of multi-focus images from each viewpoint. This paper thus tries to apply the SFF/SFD for multiple sets of multi-focus images from different viewpoints in order to reduce the estimation error, and gives some experimental results to illustrate its validity.

When a facial image is used for biometrics authentication, it is necessary to adjust the size and angle based on the orientation estimated from facial parts such as eyes, nose and mouth. The accuracy decreases if some of these parts are occuluded by hair, glasses, mask, hat or cap, and so on. This paper proposes a method to estimate facial orientation by using shape features of the additional objects and occuluded facial region. This paper discusses how to realize a method to estimate facial orientation by experimental results.

In this paper, we propose a method of frame synchronization for asynchronous multiple videos. Frame synchronization is necessary for integration of multiple videos. In this work, we focus on simultaneity of object motion and its changes which are observed as optical flows. We calculate amount of shift frames by evaluating correlation between two histories of the motions. We also show an experimental result for verification of effectiveness of our method.

We have already proposed a texture reconstruction method using statistical property of DCT coefficient. The conventional method can make texture reconstruction image of natural subjective quality. However, the conventional method has a problem that discontinuities of block border degraded texture reconstruction image quality. Therefore, we purpose quality improvement of the conventional method. The experimental results showed that the proposed method can make natural quality than the conventional method.
