Land mine detection [ ] By analyzing the emissivity of ground surfaces, multispectral imaging can detect the presence of underground missiles. Li, Ning; Zhao, Yongqiang; Pan, Quan; Kong, Seong G. Each acquires one digital image in remote sensing, called a 'scene' in a small spectral band. Because mid-wave infrared MWIR and long wave infrared LWIR technologies measure radiation inherent to the object and require no external light source, they also are referred to as methods.
They are usually represented with red, green, and blue channels. Multispectral analysis has assisted in the interpretation ofsuch as those found atby imaging the fragments in the infrared range 1000 nm.
The red detector acts as a backdrop, verifying realms of undisturbed soil areas, as it is sensitive to the 10. However, LWIR operates better in hazy environments like smoke or fog because less occurs in the longer wavelengths. This use of training samples for classification is called supervised classification.
However, beyond a certain limit the same class will be represented in different classes in the sense that variation in the class is represented. Such images allow the water depth, vegetation coverage, soil moisture content, and the presence of fires to be seen, all in a single image. Surface and Archaeological Methods and Applications in Multispectral Image Processing soil possess different physical and chemical properties that appear in spectral analysis. Blue-NIR-MIR, where the blue channel uses visible blue, green uses NIR so vegetation stays greenand MIR is shown as red.
Multispectral imaging combines two to five spectral imaging bands of relatively large bandwidth into a single optical system.

Classification [ ] Unlike other work, these multispectral images do not make it easy to identify directly the feature type by visual inspection. Far-infrared FIR2080—2350 nm, is used for imaging soil, moisture, geological features, silicates, clays, and fires.
The finer the threshold value, the more classes there will be.
is a special case of spectral imaging where often hundreds of contiguous spectral bands are available. The scientists reported that fusing these two images increased detection capabilities. feature and allots the to its most probable class.
Far-infrared FIR , 2080—2350 nm, is used for imaging soil, moisture, geological features, silicates, clays, and fires.
Such classification is a complex task which involves rigorous validation of the training samples depending on the classification algorithm used.
These signatures are less pronounced in systems which image in many more bands than multispectral systems and when exposed to wind and, more dramatically, to rain.
520 nm, is used for atmosphere and deep water imaging, and can reach depths up to 150 feet 50 m in clear water.
The Maximum likelihood principle calculates the probability of a pixel belonging to a class i.
