Latest Patents

Ranjan is named on 1 patent: “Image Generation System with Controllable Scene Lighting.” The invention describes an electronic device that generates images of a three-dimensional object under specified lighting and viewing conditions. A feature extractor processes scene lighting information and the object’s perspective to produce triplane features. A triplane decoder uses those features to determine diffuse and specular reflection parameters, which a volume renderer uses to create images. The system can generate a super-resolution image and compare it with ground-truth images to fine-tune its machine-learning parameters. It can also be conditioned to produce photorealistic images of human faces.

Career Highlights

The patent reflects work on machine-learning techniques for image synthesis, including the representation of lighting and reflections in rendered scenes. Ranjan’s listed company affiliation is Apple Inc.

Collaborations

Kwang M. Yi is identified as a coworker associated with Ranjan’s work.

Conclusion

Anurag Ranjan’s patent describes a controllable, machine-learning-based approach to generating realistic images, with applications that include photorealistic human faces.
