• [2026/01] EMVista v1.0 is officially released.

Overview

EMVista is a benchmark for evaluating instance-level microstructural understanding in electron microscopy (EM) images across three core capability dimensions:

1. Microstructural Perception
   Evaluates the ability to detect, delineate, and separate individual microstructural instances in complex EM scenes.
2. Microstructural Attribute Understanding
   Measures the capacity to interpret key microstructural attributes, including morphology, density, spatial distribution, layering, and scale variation.
3. Robustness in Dense Scenes
   Assesses model stability and accuracy under extreme instance crowding, overlap, and multi-scale complexity.

EMVista contains expert-annotated EM images with instance-level labels and structured attribute descriptions, designed to reflect realistic challenges in materials microstructure analysis.
