Abstract
One embodiment of the present invention sets forth a technique for performing estimation of scene parameters associated with a two-dimensional (2D) input scene. technique includes identifying, based on the input scene, one or more line segments included in the input scene and generating one or more vanishing points associated with the input scene based on the one or more line segments. The technique also includes estimating, based on the one or more vanishing points, one or more scene parameters associated with the scene and inserting a world object into the input scene based on the one or more scene parameters.
Claims20
A computer-implemented method for performing estimation of scene parameters, the computer-implemented method comprising:
- transforming a two-dimensional (2D) input scene from an image space representation into a latent feature space representation;
- performing a search of the latent feature space representation based at least on a latent feature vector representation of a straight line;
- identifying one or more straight line segments included in the input scene based at least on one or more results obtained from the search;
- generating one or more vanishing points associated with the input scene based on the one or more line segments;
- estimating, based on the one or more vanishing points, one or more scene parameters associated with the scene;
- and
- inserting a world object into the input scene based on the one or more scene parameters.
One or more non-transitory computer-readable media storing instructions that, when executed by one or more processors, cause the one or more processors to perform the steps of:
- transforming a two-dimensional (2D) input scene from an image space representation into a latent feature space representation;
- performing a search of the latent feature space representation based at least on a latent feature vector representation of a straight line;
- identifying one or more straight line segments included in the input scene based at least on one or more results obtained from the search;
- generating one or more vanishing points associated with the input scene based on the one or more line segments;
- estimating, based on the one or more vanishing points, one or more scene parameters associated with the scene;
- and
- inserting a world object into the input scene based on the one or more scene parameters.
A system comprising:
- one or more memories storing instructions;
- and
- one or more processors for executing the instructions to:
- transform a two-dimensional (2D) input scene from an image space representation into a latent feature space representation;
- perform a search of the latent feature space representation based at least on a latent feature vector representation of a straight line;
- identify one or more straight line segments included in the input scene based at least on one or more results obtained from the search;
- generate one or more vanishing points associated with the input scene based on the one or more line segments;
- estimate, based on the one or more vanishing points, one or more scene parameters associated with the scene;
- and
- insert a world object into the input scene based on the one or more scene parameters.
