Title: **Innovative Contributions of Philippe P. Riglet**

Introduction

Philippe P. Riglet, an inventor based in Limeil-Brevannes, France, has made significant contributions to the field of image processing with his innovative inventions. With a total of three patents to his name, Riglet has focused on enhancing image segmentation techniques to improve the quality and efficiency of image coding.

Latest Patents

His latest patents include an advanced image segmentation device that segments images featuring a moving pattern against a fixed or quasi-fixed background. This device operates by determining the silhouette of the moving pattern and creating a segmentation image that fills this silhouette. On a pixel-by-pixel basis, it analyzes differences between the current image and previous images in a sequence, forming a binary image that differentiates between the background and the useful zone. The boundaries of the useful zone are regularized, helping to suppress irregularities in both the useful zone and the background.

Another notable patent is a subassembly for coding images that incorporates refresh correction of the data. This coding subassembly supports images consisting of at least one moving pattern against a fixed background, featuring circuits to construct a base model representative of the useful zone. The subassembly also includes circuits for initial calibration, adaptation, and the determination of movement in characteristic points, ensuring accurate coding and correction of luminance and chrominance shifts along the borders of designated zones.
