Abstract. Recent advancement in hardware and software provides the possibility of realizing full automation stereo-image tasks. This paper investigated disparity map generation from aerial images with different methods: unsupervised method supervised methods. The datasets were stereo dense matching benchmark dataset for deep learning ISPRS 2021: Vaihingen WHU MVS/Stereo Dataset released CVPR 20...
Background and Aim: Cone beam computed tomography (CBCT) produces high-quality data in periodontal diagnosis and treatment planning. The aim of this study was to compare the accuracy of CBCT with intraoral digital and conventional radiography in the measurement of periodontal bone defects. Methods and Materials: In this diagnostic research, two hundred and eighteen artificial osseous d...
We present a method to evaluate stereo camera depth accuracy in human centered applications. It enables the comparison between stereo camera depth resolution and human depth resolution. Our method uses a multilevel test target which can be easily assembled and used in various studies. Binocular disparity enables humans to perceive relative depths accurately, making a multilevel test target appl...
Computed radiography (CR) has many advantages compared with conventional radiographs, especially in image processing. Although CR is being used in chest radiography and mammography, it has not been applied to spine imaging. The purposes of this study were to formulate a set of new CR processing parameters and to test whether the resultant whole-spine radiographs visualized the spine more clearl...
OBJECTIVE To, assess the emergency department use of cervical spine radiography for alert, stable adult trauma patients in terms of utilization, yield for injury and variation in practices among hospitals and physicians. DESIGN Retrospective survey of health records. SETTING Emergency departments of 6 teaching and 2 community hospitals in Ontario and British Columbia. PATIENTS Consecutive...
what: color, motlon what, where? where: depth and reglon This paper describes a statistical integration algorithm for color, motion and stereo disparity, and introduces a realtime stereo system that can tell us where and what objects are moving. Regarding the integration algorithm, motion estimation and depth estimation are simultaneously performed by a clustering process based on motion, stere...
