GPUImage2
GPUImage2 est un framework Swift pour appliquer des filtres et effets en temps réel aux images et vidéos en utilisant le GPU. Il fournit une bibliothèque de filtres vidéo en temps réel, un moteur de manipulation géométrique d'image et un pipeline d'ombrage OpenGL pour traiter les données visuelles sur le matériel graphique.
Le framework permet la construction de pipelines d'effets visuels en enchaînant des sources d'image aux consommateurs dans des flux séquentiels. Il prend en charge le développement de shaders de fragment et de sommet personnalisés pour le traitement d'image sur mesure et offre la capacité de regrouper ces opérations en unités réutilisables via un regroupement basé sur des graphes.
Les domaines de capacité incluent l'ajustement des couleurs, la manipulation géométrique et la génération d'images synthétiques. Le système prend également en charge la superposition d'images composites, permettant à plusieurs sources d'image d'être combinées en utilisant le mélange alpha et le chroma keying.
