Researchers have developed PortraVec, a new framework designed to convert pixel-based portrait images into editable vector sketches. Unlike previous pixel-based methods that offer limited manipulation, PortraVec represents sketches using vector elements for greater flexibility. The system employs a two-stage generation module for capturing facial structure and a text-guided module for semantic editing, enabling local changes while preserving overall consistency. Experiments indicate PortraVec surpasses existing methods in structural integrity, visual quality, and semantic control. AI
