With a total of 2 patents to his name, Guichard's work has advanced the understanding and application of image analysis techniques.
Latest Patents
One of Frederic Guichard's latest patents is titled "Image Frame Fusion by Velocity Estimation Using Region Merging." This innovative process performs image frame fusion on a pixel-by-pixel basis by estimating velocities and occlusions between at least two image frames in a sequence. The method identifies possible matchings that minimize changes in a selected parameter of the image, typically the grey-level. By employing a region-growing procedure, the process reduces the number of possible matchings for each pixel. The output is a decomposition of the images into regions where pixels either move with the same velocity model or are occluded. The patent also includes a multi-scale description of velocities, segmentation of images into regions with different motion, and a correcting term for sampling errors and occlusion estimation. A preferred embodiment of this invention utilizes pyramidal calculations to enhance performance.
