Introduction

Subarna Tripathi, an accomplished inventor based in Bengaluru, India, has made significant contributions to the field of video compression technology. With a total of eight patents to her name, she continues to drive innovations that enhance multimedia experiences.

Latest Patents

Among her latest patents, Subarna has developed a pioneering framework for object tracking. This framework introduces a video compression method that utilizes parametric object and background compression. At the encoder stage, the system detects objects and segments frames into distinct regions for both the foreground object and the background. The encoder then generates crucial object motion and appearance parameters. These parameters encompass multiple aspects, including translation, scaling, and orientation, providing a comprehensive approach to object tracking. Additionally, her methodology incorporates particle filtering to accurately generate object motion parameters and establishes a 'network friendly' video representation, supporting the appearance and generalized motion of objects.

Another noteworthy patent from Subarna relates to a system and method for object-based parametric video coding. In this framework, foreground objects and their corresponding backgrounds are encoded separately using innovative parametric coding techniques. The object encoding leverages projections of coefficients to the orthonormal basis of a learned subspace, while the background is modeled using an auto-regressive (AR) process. This design advantageously allows for simultaneous reconstruction of both object and background, optimizing performance on multi-threaded and multi-processor architectures.
