Patent ID: 8558883

Claim:
A method for processing image data, comprising: obtaining an image of a live event, the image is captured by a camera and comprises a representation of an object moving in the live event; obtaining a current speed of the object which represents a speed of the object in the live event when the image is captured; accessing a baseline vector field which is computed from a fluid flow model of the object and which represents a fluid flow field around the object at a reference speed of the object, the fluid flow is defined by particles, each particle having a location and a velocity at the location, and for one of the particles, the velocity is initially defined at a reference speed of the object, the reference speed of the object differs from the current speed of the object; accessing a multiplier which is based on the current speed of the object, from among a plurality of multipliers which are based on different speeds of the object; adjusting the baseline vector field to obtain an updated vector field which represents a fluid flow field around the object at the current speed of the object, the adjusting comprises multiplying the velocity of the one of the particles by the multiplier; and using the updated vector field, providing a graphic in the image, the graphic is positioned in the image based on the representation of the object in the image and depicts the fluid flow field around the object at the current speed of the object.
