Claim 0:
1. A method performed by data processing apparatus, the method comprising generating a training set of images of an object for landmark detection, wherein generating the training set comprises:
receiving a collection of real images of an object;
estimating a pose of the object in each real image in a proper subset of the collection of real images;
creating a collection of surrogate images of the object for the training set using the estimated poses and a three-dimensional model of the object, wherein creating each of the surrogate images in the collection comprises
rendering the three-dimensional model of the object in two dimensions in a pose that is the same as a respective of the estimated poses of the object,
perturbing another characteristic of the object relative to the object in the real image from which the respective pose of the object was estimated, wherein the perturbation mimics a real-world variation in the object, and
labeling landmarks on the surrogate image based on the three-dimensional model.
