突破SAM局限!中山大学X-SAM:统一框架横扫20+分割基准
自动驾驶之心· 2025-08-12 10:37
Core Insights - The article discusses the introduction of X-SAM, a new segmentation framework that overcomes the limitations of the Segment Anything Model (SAM) by enabling multi-task processing and integrating multi-modal understanding capabilities [3][4][5]. Group 1: Limitations of SAM - SAM was initially seen as a universal solution for visual segmentation but has significant limitations, including its inability to handle multiple tasks simultaneously and its lack of understanding of textual instructions [2][5][6]. - SAM is designed for single-object segmentation based on visual prompts and cannot perform complex tasks like semantic, instance, or panoptic segmentation [6]. - The gap between visual segmentation and multi-modal understanding is highlighted, where existing models can either understand images or perform pixel-level segmentation but not both effectively [5][6]. Group 2: Innovations of X-SAM - X-SAM is designed to fill the gap left by SAM, providing a unified segmentation framework that can handle various tasks and input types [7][8]. - The architecture of X-SAM includes a dual-encoder system that processes both visual and textual inputs, allowing for a comprehensive understanding of images and instructions [12][14]. - X-SAM introduces a unified input format that standardizes how different segmentation tasks are processed, enabling the model to understand both textual and visual prompts [13][15]. Group 3: Performance and Testing - X-SAM has been tested across over 20 segmentation datasets and 7 core tasks, outperforming existing models in all categories [4][27]. - The model's performance metrics include achieving an average precision (AP) of 47.9 to 49.7 in visual grounding segmentation (VGD), significantly surpassing previous models [26][35]. - In specific tasks, X-SAM achieved a panorama quality (PQ) of 54.7 in COCO panoptic segmentation, demonstrating its robustness in foundational segmentation tasks [31]. Group 4: Training Methodology - X-SAM employs a multi-stage training strategy that includes fine-tuning the segmenter, pre-training for alignment, and mixed fine-tuning across various datasets [21][23]. - The training process incorporates a data balancing resampling strategy to ensure smaller datasets are not overshadowed by larger ones, optimizing overall model performance [24]. - The model's architecture allows for simultaneous training on multiple tasks, enhancing its generalization capabilities [37]. Group 5: Future Directions - The research team plans to extend X-SAM's capabilities to video segmentation and dynamic scenes, aiming to bridge the gap between static image understanding and video comprehension [43].
