This paper proposes calibration and stereo measurement methods that enable accurate distance and uniform distribution of the distance error throughout imaging ranges. In stereo measurement using two fisheye cameras, the distance error varies greatly

We propose a new color imaging system based on a compressive sensing technique. Our system consists of a random complementary color filter array (CFA) for random projection and a color reconstruction method for demosaicing. Our CFA overlaps two compl

We propose a high-resolution and high-frame rate video imaging method in dark conditions. The proposed method consists of two steps. First, we acquired a pair of video sequences that took the same scene with different spatio-temporal resolution. One

This study describes a reconstruction method for compressive sensing using collaborative sparsity among multi-frame images and color channels. The proposed method reduces the artifact for compressive sensing and obtains better image quality. Experime

In order to synthesize intermediate-view images of arbitrary viewpoints between a pair of left and right view images, we propose two methods for disparity estimation with discontinuity at object contours. Both methods have four steps : (1) Two initia

Objectives Electrocardiogram-gated imaging combined with multi-detector row computed tomography (MDCT) has reduced cardiac motion artifacts, but it was not practical in the emergency setting. The purpose of this study was to evaluate the ability of a

In this study, we realize high-resolution (4K-format), small-size (1.43 x 1.43 μm pixel pitch size with a single imager) and high-sensitivity (four times higher sensitivity as compared to conventional imagers) video camera system. Our proposed syste
