Multispectral image compression

Proceedings. Fourteenth International Conference on Pattern Recognition (Cat. No.98EX170), 2002
Image compression has been one of the mainstream research topics in image processing. The research usually focuses on compressing images that are visible to humans. Images are usually gray-level images or RGB color images. Advances in technology enable one to make the detailed processing of spectral color features in the images.

Multispectral imager modeling

SPIE Proceedings, 2005
This paper describes the modeling of multispectral infrared sensors. The current NVESD infrared sensor model, NVTherm, models single spectral band sensors. The current NVTherm model is being updated to model third generation multispectral infrared sensors.

Multispectral Satellite Image Processing

2016
Having begun in the 1970s with the American Landsat program, the use of optical satellite images for civilian purposes has since experienced significant technological advancements. In the space of 10 years, the images provided by Earth observation satellites have gone from high to very high spatial resolution, from a decametric resolution to a ...

Multispectral Imaging Simulation

SPIE Proceedings, 1987
Current aircraft have a requirement to operate at night and in adverse weather where optical imaging systems are inoperable. Imaging sensors operating at other wavelengths have the potential to provide vision through severe weather, but these systems need to be simulated before assuming the technological and financial risks involved in hardware ...

Advances in Multispectral Confocal Imaging

Confocal, Multiphoton, and Nonlinear Microscopic Imaging, 2003
Due to the tendencies in biological research towards multiple stainings and increased use of newly developed dyes like fluorescent proteins, the application areas of multispectral confocal imaging increase rapidly. We present here the most recent advances in this technology, particularly concerning but not limited to the excitation module, the ...

Galileo multispectral imaging of Earth

Journal of Geophysical Research: Planets, 1995
Nearly 6000 multispectral images of Earth were acquired by the Galileo spacecraft during its two flybys. The Galileo images offer a unique perspective on our home planet through the spectral capability made possible by four narrowband near‐infrared filters, intended for observations of methane in Jupiter's atmosphere, which are not incorporated in any ...

Multispectral analysis of multimodal images

Acta Oncologica, 2009
An increasing number of multimodal images represent a valuable increase in available image information, but at the same time it complicates the extraction of diagnostic information across the images. Multispectral analysis (MSA) has the potential to simplify this problem substantially as unlimited number of images can be combined, and tissue properties

Wavelet-Based Multispectral Image Restoration

IGARSS 2008 - 2008 IEEE International Geoscience and Remote Sensing Symposium, 2008
In this paper, restoration of multispectral images is performed. The presented procedure is based on an Expectation-Maximization algorithm, which applies iteratively a deconvolution and a denoising step. The deconvolution step is a Landweber iteration step, while in the denoising step wavelet shrinkage is performed. The restoration is improved by using

Multispectral imaging of hand eczema

Contact Dermatitis, 2019
AbstractBackgroundHand eczema is a disease with large variation in clinical presentation and severity. Scoring systems for quantitative severity assessment exist. However, they are observer‐dependent. An objective quantitative tool for scoring of hand eczema would improve categorization of hand eczema.ObjectiveTo investigate the usefulness of ...
