 EfficientViT-SAM: A New Family of Accelerated Segment Anything Models

The Evolution of Image Segmentation with EfficientViT-SAM

Introduction

The introduction of the Segment Anything Model (SAM) has revolutionized image segmentation, but its computational intensity has limited its practical application. The development of EfficientViT-SAM aims to enhance SAM’s efficiency without sacrificing accuracy, opening up possibilities for wider-reaching applications of powerful segmentation models, even in resource-constrained scenarios.

EfficientViT-SAM Models

EfficientViT-SAM introduces two variants, EfficientViT-SAM-L and EfficientViT-SAM-XL, which offer a nuanced trade-off between operational speed and segmentation accuracy. These models have been trained end-to-end using the comprehensive SA-1B dataset, ensuring their adaptability to various segmentation scenarios.

Key Features of EfficientViT-SAM

EfficientViT-SAM utilizes the EfficientViT architecture to revamp SAM’s image encoder, ensuring a seamless fusion of multi-scale features and enhancing the model’s segmentation capability. The model’s training process incorporates a mix of box and point prompts, employing a combination of focal and dice loss to fine-tune its performance.

Empirical Performance

EfficientViT-SAM demonstrates an acceleration of 17 to 69 times compared to SAM, with a significant throughput advantage despite having more parameters than other acceleration efforts. Its zero-shot segmentation capability is evaluated through meticulous tests on COCO and LVIS datasets, showcasing superior segmentation accuracy.

Practical AI Solutions

EfficientViT-SAM represents a practical AI solution for middle managers looking to leverage AI for their advantage. It offers substantial efficiency gains without sacrificing performance, and its open-source nature encourages further research and development in the field of image segmentation.
