Title: Joan Bruna Estrach: Innovator in Video Analysis Technology
Introduction
Joan Bruna Estrach is a prominent inventor based in Paris, France. She has made significant contributions to the field of video analysis technology, holding a total of 5 patents. Her work focuses on robust motion estimation and cadence detection in interlaced video signals.
Latest Patents
One of her latest patents is titled "Video sequence analysis for robust motion estimation." This method involves computing first matching energies for individual local displacements between frames of a video sequence. It utilizes a first window around a pixel to determine a minimum of the first matching energies. The process also includes computing second matching energies for motion configurations that consist of multiple local displacements. If none of the second matching energies meet a specific criterion, a local displacement associated with the minimum of the first matching energies is selected. Conversely, if at least one motion configuration meets the criterion, a group of local displacements is formed, and third matching energies are computed for that group using a smaller second window.
Another significant patent is "Cadence detection for interlaced video based on temporal regularity." This method analyzes an interlaced video signal, applying a temporal regularity estimation process to compute metrics from sequences of fields. The process involves comparing metrics derived from different sequences to determine the time arrangement of the fields in the original sequence.
