B-Spar: Bayesian Sparse-Reward Modeling for RL-based Image Editing

shusong xu, Peiye Liu, Yongbin Liu, Bangjie Yin, Zhaomang Sun, Zhenyu Chen +7

ICML 2026poster

Autonomous image-editing agents powered by multimodal large language models (MLLMs) improve transparency and controllability by translating high-level instructions into tool-mediated edit sequences, but training such agents with reinforcement learning often relies on dense proxy rewards (e.g., incre…

A robust feature descriptor based on multiple gradient-related features

Zhaomang Sun, Fei Zhou, Qingmin Liao

ICASSP 2017accepted

In this paper, we propose a robust descriptor named as multiple gradient-related features (MGRF) in virtue of local and overall order encoding. Specifically, three types of features are introduced, including multidirectional gradient, gradient orientation, and first derivative of gradient orientatio…
