(PDF) Geometric Distortion and Correction Methods …

WebGeometric distortions refer to distortions in the shape or location of an object in an image when compared to its actual shape or location on the Earth's surface. Geometric distortions can be caused by a number of factors in remote sensing, including sensor and platform characteristics, atmospheric conditions, and terrain variations. Some of the most … WebMar 12, 2016 · Preprocessing is an important process that enables better results of the image classification. Preprocessing can be divided into four steps: noise removal, radiometric correction, geometric correction, and fusion (e.g., pansharpening). (a) Satellite imagery, especially in high resolution, has a common occurrence of noise. simpsons russian cartoon
