Title (EN) IMAGE COMPRESSION/DECOMPRESSION IN A COMPUTER VISION SYSTEM
(FR) COMPRESSION/DÉCOMPRESSION D'IMAGE DANS UN SYSTÈME DE VISION ARTIFICIELLE
Abstract:
(EN) A computer vision system (100) includes: a camera capture component (110) configured to capture an image from a camera (124); a memory (126); and an image compression decompression engine (ICDE) (118) coupled to the memory (126) and configured to receive each line of the image, and compress each line to generate a compressed bit stream. To compress a line, the ICDE (118) is configured to divide the line into compression units, and compress each compression unit. To compress a compression unit, the ICDE (118) is configured to perform delta prediction on the compression unit to generate a delta predicted compression unit, compress the delta predicted compression unit using exponential Golomb coding to generate a compressed delta predicted compression unit, and add the compressed delta predicted compression unit to the compressed bit stream.
(FR) La présente invention concerne un système de vision artificielle (100) qui comprend : un composant de capture de caméra (110) configuré de sorte à capturer une image à partir d'une caméra (124); une mémoire (126); et un moteur de compression-décompression d'image (ICDE pour Image Compression Decompression Engine) (118) couplé à la mémoire (126) et configuré de sorte à recevoir chaque ligne de l'image, et à compresser chaque ligne pour générer un flux de bits compressé. Pour comprimer une ligne, le moteur ICDE (118) est configuré de sorte à diviser la ligne en unités de compression et à compresser chaque unité de compression. Pour compresser une unité de compression, le moteur ICDE (118) est configuré de sorte à effectuer une prédiction delta sur l'unité de compression pour générer une unité de compression prédite delta, à compresser l'unité de compression prédite delta à l'aide d'un codage de Golomb exponentiel pour générer une unité de compression prédite delta compressée, et à ajouter l'unité de compression prédite delta compressée au flux de bits compressé.
