Comics and illustrations have a visual representation of the motion of an object while being a still image. I get a hint from it, I propose the method of comic expression to express a still image them by extracting the motion information of the moving object. In the paper, I explain the extraction method of motion feature and method of conversion to cartoon pattern, and I introduce the application examples of the proposed method.

This paper addresses an estimation problem of the ball's state of spin in RoboCup Small Size League (SSL). A spinning ball varies its speed after the ball bounces off the floor. This paper proposes an image-based estimation method of the ball's state of spin, in particular, by using inertia feature of co-occurrence matrix of the image sequence. The effectiveness of our proposed method is shown by some experiments.

In this paper, we propose a method of generating a video sequence with camera-work features from a set of multiple-view videos shot by multiple smart-phones. We consider adding camera-work features to the switching-based visualization of the scene. Furthermore, we focus to a controll of time progress, viewing direction to an object, by using key-frame configurations. And, we also show several experimental results for a basketball scene from set of 19 view videos.

In this report, we explain a method to calibrate multiple cameras based on their videos which are shot with handheld operation. Here, we assume a situation of shooting sports game. In this case, lines of a sports fields are main key of camera calibration for each frame of videos. We propose a method to calibrate the camera by fitting the extracted lines with the 3D model of them. And, we show several experimental results of the calibration by proposed method for a real football game scene.

This paper presents a method of moving objects tracking by using a group of three-dimensional points obtained from a depth sensor. In moving objects tracking with three-dimensional points, we can estimate the positions and postures of objects by applying templates of points from multiple viewpoints. Although the estimation accuracy is increased with the number of points, the estimation time is increased too. In this paper, we examine fast and robust moving objects tracking by using feature points of three-dimensional shape.

We proposed a content delivery service by which users can select viewing program contents by the on-air time in addition to selecting them by the program unit. We made a prototype video-on-demand system which has long-term broadcasting contents and on which user can view program contents while zapping along the on-air time axis. In this paper we report experimental results of user's behavioral pattern.

We conducted a subjective evaluation experiment to determine the optimal frequency characteristics for a car audio system during vehicle travel . In this experiment, the car interior noise typically generated when a vehicle travels at a speed of 60 km/h was added to the experimental sound sources, and subjective evaluation was made of the sound passed through filters modifying the frequency characteristics. These results confirmed that taking frequency characteristics into account in the performance of a car audio system during travel is effective in improving car interior comfort.

Shape From Focus/Defocus (SFF/SFD) has been known as a depth estimation technique by using focus information, which gives the depth estimation based on a blockwise focus measure calculated from a set of multi-focus images. The authors have proposed an error reduction technique for SFF which applies a spectral shaping (SS) filter, whose frequency response is a reciprocal of the lens point spread function (PSF), to the focus measure defined as the squared sum of a BPF output. However, this technique cannot reduce the estimation error sufficiently because of the error in the frequency response of the SS filter. To further reduce the estimation error, this paper proposes a new technique that compensates for the spectral error by a weighted sum of two BPF outputs.
