1. A method for setting parameters for image analysis of ultrasound images, the method comprising: obtaining ultrasound data of an object; generating an image of the object; identifying a region of interest in the image; mapping from the region of interest into a parameter within a predefined parameter space, wherein the mapping maps a plurality of sections in a normalized image domain to one of a scalar value or a vector value corresponding to parameters of an image analysis algorithm used to perform the image analysis; determining a plurality of spatially varying parameters for the image analysis of the region of interest using the mapping and prior information for one or more objects of interest, wherein the prior information comprises prior location information for the one or more objects of interest, wherein the plurality of spatially varying parameters is determined for a plurality of sections of the region of interest, and wherein at least some of the plurality of sections of the region of interest have different spatially varying parameters; using the plurality of spatially varying parameters for performing the image analysis of the region of interest in the image to determine a location of the one or more objects of interest.
