In this work we address various segmentation tasks each traditionally tackled by distinct or partially unified models. We propose OMG-Seg One Model that is Good enough to efficiently and effectively handle all the segmentation tasks including image semantic instance and panoptic segmentation as well as their video counterparts open vocabulary settings prompt-driven interactive segmentation like SAM and video object segmentation. To our knowledge this is the first model to handle all these tasks in one model and achieve satisfactory performance. We show that OMG-Seg a transformer-based encoder-decoder architecture with task-specific queries and outputs can support over ten distinct segmentation tasks and yet significantly reduce computational and parameter overhead across various tasks and datasets. We rigorously evaluate the inter-task influences and correlations during co-training. Code and models are available at https://github.com/lxtGH/OMG-Seg.
