Title: Dileep Kumar Tamia: Innovator in Motion Estimation and Bit Rate Control
Introduction
Dileep Kumar Tamia is a notable inventor based in Karnataka, India. He has made significant contributions to the fields of motion estimation and bit rate control, holding a total of 3 patents. His work has implications in video encoding standards, enhancing the efficiency and quality of video transmission.
Latest Patents
One of his latest patents is a "Fast motion-estimation scheme." This motion estimation algorithm identifies the best match for a given block or macroblock, ensuring that the resulting error signal maintains a very low energy level, which can be computed using methods such as the SAD method. The algorithm also allows for optional sub-pixel level estimation and inter4v search, while restricting the number of searches for Frame-frame motion estimation. It features a selective early exit and enables the selection of a suitable search area with N candidate points, which can range from 4 to 8. The search is conducted progressively until a minimum error signal is achieved. The candidate points may be arranged in a diamond-shaped configuration, with multiple successive diamond configurations that are configurable. This invention is applicable in MPEG-4 and H.264 standards.
Another significant patent is the "Model based bit rate control for a macroblock encoder." This method achieves bit rate controlled encoding, such as constant bit rate, by utilizing a bit rate control model based on bits allocated per macroblock and the error in estimating bits consumed during the encoding process. The model computes bits consumed per macroblock as a function of the established bit rate control model and allocates bits accordingly. A quadratic equation is employed for the model, which can default to a first-order equation if no second-order solutions are available. This model ensures compliance with video buffer verifier (VBV) requirements in accordance with MPEG standards and accommodates various types of macroblocks, including inter, intra, or bidirectional.
