El GPI fa recerca en Processament d'Imatge i Vídeo per representació, codificació, indexació i anàlisi del contingut visual. L'expertesa del grup en Morfologia i segmentació ha estat la base de contribucions als estàndards ISO MPEG-4 i MPEG-7. La recerca en anàlisi d'imatge l'ha permès participar en projectes europeus des de 1992 als programes RACE (Morpheco, coord.), ACTS (MAVT, MoMuSys, Vidas), IST (Diceman, Hypermedia, INTERFACE, ADViSOR, MASCOT, FAETHON), xarxes d'excel·lència (SCHEMA, SIMILAR, MUSCLE), i projectes integrats FP6 (CHIL) i FP7 (FASCINATE).

El Grupo de Procesado de Imagen y Vídeo investiga técnicas de tratamiento de imagen y vídeo en los campos de compresión, análisis, indexación, representación e interfaces multimodales. El Grupo se ha especializado en herramientas básicas de filtrado no lineal y morfología matemática, segmentación, seguimiento de objetos, detección y reconocimiento de caras, análisis de emociones y modelitzación de la actividad humana, que han sido la base de aplicaciones de codificación basada en el contenido, representación de vídeo mediante índices y tablas de contenido, y contribuciones a estándares internacionales como MPEG4 y MPEG7. El Grupo también desarrolla aplicaciones biomédicas, de teledetección y marcado.

The research of the Image and Video Processing Group focuses on the areas of compression, analysis, indexing, representation and multimodal interfaces. The group specialises in basic tools for nonlinear filtering, mathematical morphology, segmentation, object tracking, face detection and recognition, emotion analysis and modelling of human activity, which have been the basis of applications related to content-based video coding, video indexing and the creation of tables of content and contributions to international standardisation processes such as MPEG-4 and MPEG-7. The group also develops biomedical, remote-sensing and watermarking applications.
