Title: Frédéric Jacquelin: Innovator in Image Motion Estimation
Introduction
Frédéric Jacquelin is a notable inventor based in Boulogne-Billancourt, France. He has made significant contributions to the field of image processing, particularly in motion estimation techniques. With a total of 2 patents to his name, Jacquelin's work has advanced the understanding and application of motion analysis in images.
Latest Patents
Jacquelin's latest patents include innovative methods for estimating motion in a series of images captured by an image sensor. One of his patents focuses on the estimation of motion vectors at various points in an image. This method involves minimizing a functional of motion vectors, which includes a data term and a regulation term. The data term is influenced by the degree of regularity of the estimated motion vectors and the spatial-temporal gradients of brightness in the surrounding area. The regulation term aids in providing a unique solution when the data term does not suffice.
Another significant patent by Jacquelin pertains to global and dense motion estimation. This method utilizes a series of images to estimate movement by first obtaining an estimated movement from a preceding image to a following image. A compensated image is then created based on this initial estimate, followed by a second estimation of dense movement between the compensated image and the other image. The process continues until a satisfactory residual value of global movement is achieved.
