1. A method of operating an image processing system, the method comprising; identifying object pixels associated with an object of interest in a scene; identifying additional pixels to associate with the object of interest; and performing an operation based on a depth of the object in the scene on target pixels comprised of the object pixels and the additional pixels to change a quality of the object of interest; identifying a vertical vanishing point of the scene; processing the vertical vanishing point and a position of the object in the scene to determine the depth of the object in the scene; identifying a height of an average human in the scene for every pixel in the scene based on the vertical vanishing point; determining a variable kernel for the operation based on the height and the depth of the object in the scene; and performing the operation on the scene using the variable kernel.
