Model overview

birefnet is an AI model for high-resolution dichotomous image segmentation, proposed in the paper "Bilateral Reference for High-Resolution Dichotomous Image Segmentation" (CAAI AIR 2024). Developed by Peng Zheng and his team, birefnet has achieved state-of-the-art performance on several benchmarks, including dichotomous image segmentation (DIS), high-resolution salient object detection (HRSOD), and camouflaged object detection (COD).

Similar models include dichotomous_image_segmentation for highly accurate DIS, and SeeSR for semantics-aware real-world image super-resolution.

Model inputs and outputs

Inputs

Image: The input image to be segmented, in any standard image format.
Resolution: The desired resolution of the output segmentation mask, in the format "WxH" (e.g., "1024x1024").

Outputs

Segmentation Mask: The predicted segmentation mask for the input image, with the requested resolution. The mask is a binary image, where 1 represents the foreground object and 0 represents the background.
