bstract. 3-D scanning has become increasingly popular in a wide ange of applications. We present a prototype 3-D/stereoscopic canning system based on a cheap, readily available flatbed scaner. Stereoscopic imaging is achieved by modifying the optical path f the ordinary flatbed scanner. The results of 3-D imaging using our rototype system are demonstrated, and a number of design lternatives are...

Repurposive appropriation is a creative everyday act in which a user invents a novel use for information technology (IT) and adopts it.This study is the first to address its prevalence and predictability in the consumer IT context. In all, 2,379 respondents filled in an online questionnaire on creative uses of digital cameras, such as using them as scanners, periscopes, and storage media. The d...

3D image reconstruction from a set of X-ray projections is an important image reconstruction problem, with applications in medical imaging, industrial inspection and airport security. The innovation of X-ray emitter arrays allows for a novel type of X-ray scanners with multiple simultaneously emitting sources. However, two or more sources emitting at the same time can yield measurements from ov...

In this study, we address the problem of recovering the cross section shape of an unfolded book from the image of its surface taken by the image scanner. To attack this problem, we propose the practical method using the eigenspaces which are constructed by some shape and intensity profile da ta L: Light SOW of the book surface to reduce the data size. In this M: Mirmr C: Lens method, the book s...

UNLABELLED Registration and fusion of whole-body functional PET and anatomic CT is significant for accurate differentiation of viable tumors from benign masses, radiotherapy planning and monitoring treatment response, and cancer staging. Whole-body PET and CT acquired on separate scanners are misregistered because of differences in patient positions and orientations, couch shapes, and breathing...

This chapter looks at the usage of remote sensing data for practical research. Remote sensing data can be used for individual applications and research studies as well as routine work, and basic data sets can be provided as vital pieces information for landscape ecological investigations. Experimental work such as tests related to sensor development, signature research and non-operational digit...

This paper presents a new light field capture system where the main design goal is low cost. To minimize cost we use an off-the-shelf flatbed scanner as the digitizing element. However, intrinsic properties of scanners can adversely affect resultant images. We will survey these properties and their effects in raw outputs. Image manipulation techniques will then be discussed so that proper light...

We describe a system for transforming an off-the-shelf flatbed scanner into a $200 scan backend for large format cameras. While we describe both software and hardware aspects, the focus of the paper is on software issues such as color calibration and removal of scanner artifacts. With current scanner technology, the resulting camera system is capable of taking black&white, color, or near-infrar...

This paper proposes a palmprint based verification system using low-order Zernike moments of palmprint sub-images. The Zernike moments of corresponding sub-images of live and enrolled palmprint are matched using Euclidean distance for verification. An efficient weighted fusion technique to fuse matching scores of the sub-images is proposed. The palmprint is extracted from the hand image acquire...

This letter describes a data acquisition setup for recording, and processing, running speech from a person in a magnetic resonance imaging MRI scanner. The main focus is on ensuring synchronicity between image and audio acquisition, and in obtaining good signal to noise ratio to facilitate further speech analysis and modeling. A field-programmable gate array based hardware design for synchroniz...
