Abstract

PROCESSO E EQUIPAMENTO DE RANDOMIZAçãO PROGRESSIVA PARA ANáLISE E RACIOCìNIO EM MULTIMìDIA A presente invenção trata de um processo e equipamento para extração de informações de alto nível em multimídia (e.g., imagens, sons, vídeos). Mais especificamente a presente invenção trata de um processo progressivo de perturbação de conteúdo multimídia visando extrair características não visíveis no estado natural do conteúdo analisado. O processo e equipamento são capazes de agregar as informações extraídas de várias classes de mídias para resolver problemas conhecidos tais como a categorização de conteúdo multimídia, detecção de mensagens escondidas, detecção de adulteração de conteúdo, criação de marcas d'água (watermarking) robustas, reconhecimento do meio originador da mídia (e.g, tipo de câmera utilizada no processo de captura) entre outras aplicações.PROGRESSIVE RANDOMIZATION PROCESS AND EQUIPMENT FOR MULTIMEDIA ANALYSIS AND REASONING The present invention is a process and equipment for extracting high level multimedia information (e.g., images, sounds, videos). More specifically the present invention deals with a progressive process of disturbing multimedia content aiming to extract features not visible in the natural state of the analyzed content. The process and equipment are able to aggregate information extracted from various media classes to solve known issues such as multimedia content categorization, hidden message detection, content tamper detection, robust watermarking, recognition of media originator media (eg, type of camera used in the capture process) among other applications.
