Project Page | Paper

This repository contains the official Pytorch implementation of training & evaluation code and the pretrained models for DDP, which contains:

• Semantic Segmentation
• Depth Estimation
• BEV Map Segmentation
• Mask Conditioned ControlNet

We use MMSegmentation, Monocular-Depth-Estimation-Toolbox, BEVfusion, ControlNet, as the correspond codebase. We would like to express our sincere gratitude to the developers of these codebases.

News

In the coming days, we will be updating the corresponding codebases.

Abstract

We propose a simple, efficient, yet powerful framework for dense visual predictions based on the conditional diffusion pipeline. Our approach follows a "noise-to-map" generative paradigm for prediction by progressively removing noise from a random Gaussian distribution, guided by the image. The method, called DDP, efficiently extends the denoising diffusion process into the modern perception pipeline. Without task-specific design and architecture customization, DDP is easy to generalize to most dense prediction tasks, e.g., semantic segmentation and depth estimation. In addition, DDP shows attractive properties such as dynamic inference and uncertainty awareness, in contrast to previous single-step discriminative methods. We show top results on three representative tasks with six diverse benchmarks, without tricks, DDP achieves state-of-the-art or competitive performance on each task compared to the specialist counterparts.
