Qwen-Image-Layered: Towards Inherent Editability via Layer Decomposition

CVPR 2026

Recent visual generative models often struggle with consistency during image editing due to the entangled nature of raster images, where all visual content is fused into a single canvas. In contrast, professional design tools employ layered representations, allowing isolated edits while preserving c

Lite DETR: An Interleaved Multi-Scale Encoder for Efficient DETR

CVPR 2023poster

Recent DEtection TRansformer-based (DETR) models have obtained remarkable performance. Its success cannot be achieved without the re-introduction of multi-scale feature fusion in the encoder. However, the excessively increased tokens in multi-scale features, especially for about 75% of low-level fea…

MP-Former: Mask-Piloted Transformer for Image Segmentation

CVPR 2023poster

We present a mask-piloted Transformer which improves masked-attention in Mask2Former for image segmentation. The improvement is based on our observation that Mask2Former suffers from inconsistent mask predictions between consecutive decoder layers, which leads to inconsistent optimization goals and…

Mask DINO: Towards a Unified Transformer-Based Framework for Object Detection and Segmentation

CVPR 2023poster

In this paper we present Mask DINO, a unified object detection and segmentation framework. Mask DINO extends DINO (DETR with Improved Denoising Anchor Boxes) by adding a mask prediction branch which supports all image segmentation tasks (instance, panoptic, and semantic). It makes use of the query e…

DN-DETR: Accelerate DETR Training by Introducing Query DeNoising

CVPR 2022oral

We present in this paper a novel denoising training method to speedup DETR (DEtection TRansformer) training and offer a deepened understanding of the slow convergence issue of DETR-like methods. We show that the slow convergence results from the instability of bipartite graph matching which causes i…

Online Convolutional Sparse Coding with Sample-Dependent Dictionary

ICML 2018oral

Convolutional sparse coding (CSC) has been popularly used for the learning of shift-invariant dictionaries in image and signal processing. However, existing methods have limited scalability. In this paper, instead of convolving with a dictionary shared by all samples, we propose the use of a sample-…
