Multispectral image matching plays a very important role in remote sensing image processing and can be applied for registering the complementary information captured by different sensors. Due to the nonlinear intensity difference in multispectral images, many classic descriptors designed for images of the same spectrum are unable to work well.

Abstract: Image fusion combines data from different heterogeneous sources to obtain more precise information about an underlying scene.

The software consists of a new interactive visualization tool targeted at multispectral and hyperspectral image data, and a toolbox of common algorithms, e.g.

Such a set of images carries information pro pixel close to those collected by DRS method in scanning mode, for instance, dimensional maps of hemoglobin oxygen saturation (SO 2) or total hemoglobin.

Multispectral imaging has also found use in document and painting analysis. Multispectral imaging measures light in a small number (typically 3 to 15) of spectral bands.

Hyperspectral imaging is a special case of spectral imaging where often hundreds of. Hyperspectral imaging, like other spectral imaging, collects and processes information from across the electromagnetic goal of hyperspectral imaging is to obtain the spectrum for each pixel in the image of a scene, with the purpose of finding objects, identifying materials, or detecting processes.

INTRODUCTION F USION of multisensor images has been explored during recent years and is still a very active research area [2]. A popular fusion problem in remote sensing consists of merging aFile Size: 1MB. As any imaging instrument, spectral imaging instruments have a limited spatial resolution – often determined by the number of pixels of some kind of image sensor.

The second key performance parameter is the spectral resolution. While multispectral imaging devices often have relatively broad wavelength bands, e.g. with a width of 20 nm or even nm, hyperspectral imagers.

hyperspectral imagery, very specific ground truth information and commercial image processing software.

• Water bodies are easily distinguished and a relative measure of their constituents (sediment, organic content) can be made without ground truth. The multispectral imaging system acquires spectral image as a Three-Dimensions data cube, as illustrated in figure 4.

The 2-dimensional image contains the spatial information of a sample, the third dimension records spectral information, and is Optical Density (OD). The spectral image shows the spectral information for each pixel. Figure 4. Multispectral imaging collects spectral information from a limited number of wavelengths (colours) whilst simultaneously recording the image.

These wavelengths can be customised for a particular application, which leads to cheaper instrumentation and simpler data processing, but without the flexibility of hyperspectral imaging systems. Hyperspectral Images: As we know the different red,green and blue coloration is due to the fact that the reflected light from objects fall under separate wavelength ranges in the visible spectrum of the electromagnetic radiation[i.e.

Hyperspectral images provide both spatial and spectral representations of scenes, materials, and sources of illumination. They differ from images obtained with a conventional RGB colour camera, which divides the light spectrum into broad overlapping red, green, and blue image slices that when combined seem realistic to the eye.Several image processing tools have been developped to allow us to perform these analyses.

The IIPImage system enables us to visualize high resolution multi-spectral 16 bit images, view image details in colour or for each spectral channel and to. However, the serial acquisition of spectral images over time prevents the ability to monitor rapid changes in vascular dynamics and cannot monitor concurrent changes in oxygenation and flow rate.
