Latest Patents

Sela’s latest patents describe computerized techniques for creating audio-based caricatures. The methods receive a three-dimensional model of an object and an audio sequence, generate a sequence of video frames featuring an exaggerated caricature, and combine the video with the audio to produce an audiovisual clip.

One method computes the caricature by applying a computerized caricaturization algorithm to the three-dimensional model. It scales gradient fields of the model’s surface coordinates according to a function of the surface’s Gaussian curvature, then finds a regular surface whose gradient fields fit the scaled fields. The exaggeration factor can vary across video frames and is determined using one or more parameters of the musical composition.

A related method likewise varies the exaggeration factor across frames based on parameters of the audio sequence. Together, the inventions describe ways to coordinate visual caricature effects with sound.

Career Highlights

Sela’s listed patent portfolio comprises 2 patents, both concerning audio-based caricature exaggeration. His work connects three-dimensional modeling, surface geometry, animation, and audiovisual synthesis.
