Category classification with ROIs using object detector

Visual category recognition is challenging in computer vision and has several problem. Some of problems on visual category recognition are variance to the object instance position and background clutter. In this paper, we propose method select region of interest(ROI) in training and recognizing automatically. This provide invariance to object instance position and removing background clutter. In training phase, we make object detector to select ROI in recognizing automatically. The object detector is made by training regions of object and non-object, which determine a ROI without user annotation by using class label and some same class image of set of training image set. In this paper, the set of experiments is on the image database. We prove our proposed method can achieve high accuracy and recognize object position in training and recognizing

Computation Time of Grid Computing with Data Transfer Times that Follow a Gamma Distribution

The computation time of grid computing has rarely been evaluated for the case in which the computers used for calculation are scattered over the Internet. In the present paper, we assume that the data transfer times follow a gamma distribution and clarify the characteristics of the probability distribution of the computation time.

3D display system using monocular multiview displays

A 3D head mounted display (HMD) system is useful for constructing a virtual space. The authors have researched the virtual-reality systems connected with computer networks for real-time remote control and developed a low-priced real-time 3D display for building these systems. We developed a 3D HMD system using monocular multi-view displays. The 3D displaying technique of this monocular multi-view display is based on the concept of the super multi-view proposed by Kajiki at TAO (Telecommunications Advancement Organization of Japan) in 1996. Our 3D HMD has two monocular multi-view displays (used as a visual display unit) in order to display a picture to the left eye and the right eye. The left and right images are a pair of stereoscopic images for the left and right eyes, then stereoscopic 3D images are observed.

A 3-D head-mounted-display (HMD) system is useful for constructing a virtual space. We have developed a 3-D HMD system with a monocular stereoscopic display. This paper describes a stereoscopic image capturing camera that uses the camera position shifting optics to capture monocular stereoscopic images. It also describes the characteristics of spatial reconstruction when the parallax interval and viewing angle have been changed.

In this paper, we propose the monocular stereoscopic 3D display and capturing camera for a tele- manipulation system. In addition, we describe the result of depth estimation using the multi-focus retinal images.

Head-mounted 3D display system using monocular stereoscopic display

A 3D head mounted display (HMD) system is useful for constructing virtual space. The authors have developed a see-through 3D HMD system. This display has no demerit that lightness of real and virtual images is lacking for a spatial viewing. This paper shows that this problem can be solved by using a simultaneous perception of the human vision and a 3D vision system. In addition, we propose a newly developed monocular stereoscopic 3D display system for this 3D HMD system.

A 3-D head mounted display (HMD) system is useful for constructing a virtual space. We have developed a 3-D HMD system. Traditional displays have drawbacks in that the lightness of real and virtual images is insufficient for spatial viewing.
