ICE-CAMERA: a flatbed scanner to study inland Antarctic polar precipitation
نویسندگان
چکیده
Abstract. Studying precipitation at very high latitudes is difficult because of the harsh environmental conditions that limit external activity humans and instruments, especially in polar winter. The direct monitoring ice crystal habits size distribution Antarctic important for validation algorithms used retrieving from ground-based satellite-borne radar instruments improvement climatological modelling areas. This paper describes an automated device (ICE-CAMERA) specifically developed imaging, measurement, classification on plateau. instrument gives detailed information hourly basis. article provides a description its image processing software. Starting 2014, has operated almost unattended all year round Concordia station, Antarctica (75∘ S, 123∘ E, 3220 m altitude).

Transform your Digital Camera into a Flatbed Scanner
We propose to extend the use of a digital camera to a new application, which consists basically in transforming it into a flatbed scanner. Our approach consists in simulating the flattening of warped documents, by means of computer vision techniques. In particular, with regard to the digitization of a book, we show that the drawbacks related to the use of a scanner can be bypassed. The correcti...

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...
متن کامل0.5 gigapixel microscopy using a flatbed scanner.
The capability to perform high-resolution, wide field-of-view (FOV) microscopy imaging is highly sought after in biomedical applications. In this paper, we report a wide FOV microscopy system that uses a closed-circuit-television (CCTV) lens for image relay and a flatbed scanner for data acquisition. We show that such an imaging system is capable of capturing a 10 mm × 7.5 mm FOV image with 0.7...

Microscopy imaging systems with a very wide field-of-view (FOV) are highly sought in biomedical applications. In this paper, we report a wide FOV microscopy imaging system that uses a low-cost scanner and a closed-circuit-television (CCTV) lens. We show that such an imaging system is capable to capture a 10 mm * 7.5 mm FOV image with 0.77 micron resolution, resulting in 0.54 gigapixels (10 9 pi...
متن کاملErratum: 0.5 gigapixel microscopy using a flatbed scanner: erratum.
When one uses USAF target to calibrate the resolution of an imaging system, the periodicity of the smallest resolvable line should be used to define the limit. However, in the original paper, the line width of the resolution target was used to characterize the resolution of our microscope system, resulting in an overestimation of the performance of the imaging system. In this erratum, we correc...
