Update 1 for ERDAS IMAGINE 2018 is primarily aimed at improving the NNDiffuse pan sharpening technique which was initially introduced with ERDAS IMAGINE 2018. The update provides OpenCL-based GPU acceleration for the technique, which in some instances can result in a two orders of magnitude increase in performance. The algorithm has also been fine-tuned to provide even better color fidelity compared to the original Multispectral data.
In addition, there are new Operators, such as the Linear Regression operator, as well as numerous software quality improvements.
