E.g., in satellite remote sensing, ... preliminary analysis of data prior to supervised classification 12 GNR401 Dr. A. Bhattacharya. Role of Image Classifier The image classifier performs the role of a discriminant – discriminates one class against others
image acquired by remote sensing ultimately depends upon detection of differences in the brightness of objects and the features. Radiometric Resolution: This is the sensitivity to small differences in the radiation of an observed object. •MSS = 6 bits •Landsat TM = 8 bits •IKONOS – 11 bits •ERS SAR = 16 bits A KEY CONCEPT OF REMOTE ...
Singh in 1989 [19] and Coppin and Bauer in 1996 [20]. These articles discussed only remote sensing methodologies. Here, we focus on more recent work from the broader (English-speaking) image analysis community that reflects the richer set of tools that have since been brought to bear on the topic. The core problem discussed in this paper is as ...

1 Active and Passive Remote Sensing Passive remote sensing systems record EMR that is reflected (e.g., blue, green, red, and near-infrared light) or emitted (e.g., thermal infrared energy) from the surface of the Earth. Active remote sensing systems are not dependent on the Sun’s EMR or the thermal properties of the Earth.

velocity medium (Figure 1.3b). There are other gathers, such as a common image-point (CIG) gather, which is a collection of migrated traces at the same image bin location. Some people call a collection of traces with the same amount of source-to-receiver offset as a common offset gather, though it is logically a common offset section.
