Flow Matching Reinforcement for 3D Mesh Generation via Dynamic Homing Optimization

Flow matching is central to 3D generation, yet in practice its reinforcement learning (RL) methods are largely adapted from 2D visual generation. Representative DPO-, GRPO-, and NFT-style objectives, when applied to negative trajectories, mainly steer predicted velocities away from the corresponding directions without...

SAM-BoMu: Boundary-Aware Multi-Channel Fusion Network for Precise Polyp Segmentation.

A SAM-based boundary-aware multi-channel fusion network named SAM-BoMu, which consists of a Multi-Channel Encoder (MCE) and a Multi-Fusion Decoder (MFD), and introduces a Boundary-Constrained Hybrid Fusion (BCHF) module into the MFD to utilize these features for enhancing the segmentation performance.

Flow3D-OPD: Multi-Teacher On-Policy Distillation for 3D Geometry Generation with Flow-Matching Diffusion Transformer

This work proposes Flow3D-OPD, a two-stage post-training framework that introduces multi-teacher distillation into 3D geometry generation and achieves consistent improvements across all geometric quality dimensions and surpasses all teacher models in the average metric.
