Title: Sumantra Dutta Roy: Innovator in Video Compression Technology
Introduction
Sumantra Dutta Roy is a prominent inventor based in New Delhi, India. He has made significant contributions to the field of video compression technology, holding a total of 3 patents. His innovative work focuses on enhancing the efficiency and quality of video encoding through advanced methodologies.
Latest Patents
One of his latest patents is centered around object tracking, where he proposes a video compression framework based on parametric object and background compression. In this framework, the encoder detects objects and segments frames into regions corresponding to the foreground object and the background. The encoder generates object motion and appearance parameters, which include translation, scaling, and orientation parameters for the object. Additionally, particle filtering is employed to generate the object motion parameters. This methodology formalizes the concept of perceptual quality scalability for regions of interest, aiming for a 'network friendly' video representation that supports the appearance and generalized motion of objects.
Another notable patent is the system and method for object-based parametric video coding. This framework also focuses on video compression through the detection and segmentation of objects and backgrounds. The object is encoded using a projection of coefficients to the orthonormal basis of a learned subspace, while the background is characterized using an auto-regressive process model. A key advantage of this approach is that it allows for the simultaneous reconstruction of both object and background, making it suitable for modern multi-thread and multi-processor architectures.
