Image processing and analysis

3 stages: Image Restoration correcting errors and distortion. Warping and correcting systematic distortion related to viewing geometry Correcting "drop outs", striping and other instrument noise Applying corrections to compensate for atmospheric absorbtion & radiance Image Enhancement emphasizing the information that is of interest Spatial Filtering to enhance or suppress features on the basis of size Contrast enhancement to emphasize subtle tonal variations. Image Analysis extracting specific information for subsequent analyses Principal component transformations Multispectral classification Temporal Variation
