Multispectral Satellite Image Processing
2016Having 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, 1987Current 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, 2003Due 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, 1995Nearly 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, 2009An 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, 2008In 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, 2019AbstractBackgroundHand 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 ...

Multispectral images are a particular class of images that require specialized coding algorithms. In multispectral images, the same spatial region is captured multiple times using different imaging modalities. These modalities often consist of measurements at different optical wavelengths (hence the name multispectral), but the same term is sometimes ...

In this chapter we discuss the non-photographic multispectral imaging systems operating in the optical range of the electromagnetic spectrum. The optical range has been defined as that range in which optical phenomena of reflection and refraction can be used to focus the radiation.

Multispectral Imaging Techniques
2017In this chapter we discuss the principle of non-photographic multispectral imaging systems. A digital sensor comprises of a detector part and an optical part. Various types of photo conductive detectors are used for quantifying the radiation intensity. Resolution of a sensor is considered in terms of spatial resolution, spectral resolution, radiometric
