BR-Gen
收藏资源简介:
BR-Gen是一个大规模、高质量的图像数据集,包含150,000张局部篡改的图像,涵盖了多样化的场景感知标注。该数据集由教育部多媒体可信感知与高效计算重点实验室(厦门大学)构建,通过全自动的感知-创建-评估管道,确保了数据的语义完整性和视觉真实性。数据集针对以前数据集忽视的‘事物’和‘背景’类别,如天空、地面、墙壁、草地和植被等,极大地扩展了局部篡改图像的范围。
BR-Gen is a large-scale, high-quality image dataset containing 150,000 locally tampered images with diverse scene-aware annotations. Developed by the Key Laboratory of Multimedia Trusted Perception and Efficient Computing, Ministry of Education, Xiamen University, this dataset adopts a fully automatic perception-creation-evaluation pipeline to ensure the semantic integrity and visual authenticity of the data. It greatly expands the scope of locally tampered images by targeting previously neglected object and background categories such as sky, ground, wall, grassland and vegetation.
