Functions
WlzObject *	WlzGreyVariance (WlzObject *inObj, int newObjFlag, int kernelSz, double scale, WlzErrorNum *dstErr)
	Uses a small kernel to compute the local variance of the given grey value object. Only objects with WLZ_EMPTY_OBJ and WLZ_2D_DOMAINOBJ types are valid. WLZ_2D_DOMAINOBJ objects must have a valid domain and integral (ie WLZ_GREY_INT, WLZ_GREY_RGBA, WLZ_GREY_SHORT or WLZ_GREY_UBYTE) values. More...
