Luckily, there is a simple algorithm that can be applied to a data set to determine if a point is a maximum or minimum. The algorithm works by checking the point to the left and to the right for the i-th point and seeing if the i-th point...
Performing band math with the new ENVI API can be a little daunting compared to the simplistic approach of the ENVI Classic routines such as MATH_DOIT. While there is some overhead associated with how to use IDL with the new ENVI API, this example makes use of the tile iterator which can be used to greatly speed up processing time and...
The Independent Components (IC) analysis is used to transform a set of mixed, random signals into components that are mutually independent for multispectral or hyperspectral datasets. The ICA transform produces a transformation matrix of the forward and backward transformation coefficients that are stored in a '.trans'...
