<element name="DESCRIPTION" text="This algorithm reduce the effects of sensor differences when comparing images from two dates. Calibration can be done aplying two different methods: Adjusting the image so it has a given average and standard deviation values, or applying some given gain and offset values. In the first case, it uses the formula: NDC = (((ND - average) / standard_deviation) x typical_deviation) + image_average In the second case, the following formula is used: NDC = gain x ND + offset " description="Description" type="0"> |
