Core Insights - PosterGen is a multi-agent framework designed to convert academic papers in PDF format into aesthetically pleasing and fully editable PPTX format posters, addressing the time-consuming nature of poster design for researchers [2][4][51]. Group 1: Innovation and Functionality - The core innovation of PosterGen lies in its ability to automate the poster creation process while adhering to essential design principles, thus minimizing the need for manual adjustments [2][9]. - PosterGen establishes an end-to-end workflow that liberates researchers from the tedious task of poster design, allowing them to focus on the core value of academic communication [9][51]. Group 2: Design Principles - PosterGen incorporates four core design principles derived from professional design knowledge, ensuring that the generated posters are comparable to those created by human designers [27][28]. - The narrative structure follows the "And, But, Therefore" (ABT) format, which helps in logically presenting the research background, challenges, and solutions [27]. - A three-column grid layout is utilized to maintain order in information delivery, ensuring a natural reading flow and effective use of white space to reduce visual clutter [27][28]. Group 3: Aesthetic Elements - The color scheme is designed to establish hierarchy and ensure readability, employing a restrained monochromatic palette that adheres to WCAG contrast standards [28]. - Typography is prioritized to enhance clarity, using sans-serif fonts and establishing visual and semantic hierarchies through size and formatting [28]. Group 4: Workflow and Agents - The PosterGen workflow consists of four collaborating agents that integrate design principles throughout the poster generation process, achieving a level of aesthetic and creative quality akin to human designers [30]. - The Parser and Curator Agents extract content from the PDF and create a coherent storyboard based on the ABT structure, setting the foundation for design [31]. - The Layout Agent translates the storyboard into a precise spatial layout, ensuring effective placement of content elements and managing spacing through a box model approach [32][34]. Group 5: Evaluation and Results - PosterGen's effectiveness is validated through a comprehensive evaluation framework that assesses both content and design metrics, demonstrating its superiority in aesthetic quality compared to existing methods [44][52]. - Quantitative results indicate that PosterGen matches state-of-the-art methods in content fidelity while significantly outperforming them in design and aesthetic metrics, particularly in theme consistency and font readability [52][53].
