Abstract
There has been significant research on specific image sharpening algorithms, but there has been less work incorporating them into a robust and validated tool. We present the Image Sharpening Toolkit (ISTK), a collection of four validated algorithms that provide error propagation and greater spectral or spatial fidelity, dependent on the user's needs. The algorithms exploit the physics of a sensor, including knowledge of its Tasseled Cap coefficients and Spectral Response Function. In addition, the HSV color model is used to fuse two single-band images and produce a color image. We demonstrate the tool's performance on QuickBird and IKONOS imagery.
