Abstract
A method of adding a virtual insertion to an image, according to an embodiment, includes extracting dynamic features from an input image, associating the dynamic extracted features with dynamic reference features in a reference feature database, generating a camera model based on the associations, mixing a virtual insertion into the input image based on the camera model, and outputting an image containing both the input image and the virtual insertion. According to another embodiment, a method of adding a virtual insertion to an image includes generating a biased camera model using a statistically selected subset of a plurality of non-fixed regions of the image, locating fixed reference objects in the image using the biased camera model as an entry point for a search, generating a corrected camera model using the fixed reference objects in the image, and adding a virtual insertion to the image using the corrected camera model.
