Abstract :
In signal processing, it is often necessary to measure the sharpness of a distribution. A class of sharpness measures is studied in this paper. First the class is defined. Then the relation between sharpness and the class is clarified, and this justifies the class as sharpness measures. In addition, in general, we investigate the effect of the kernel on the sharpness measure and present a guide to select the kernel.
