Automated radiology report generation aims to create clear and clinically correct diagnostic reports from medical images. Existing retrieval enhancement methods primarily focus on reusing textual knowledge, neglecting the crucial role of local visual pattern memory in clinical diagnosis. Furthermore
Adversarial examples expose fundamental vulnerabilities within deep neural networks, and their transferability highlights shared weaknesses across diverse models. Existing mainstream attack methods often rely on iterative processes with various strategies to improve transferability, but the limited
Deep Neural Networks (DNNs) have revolutionized numerous industries, yet their decision-making processes remain largely opaque. Most existing explanation methods visualize the importance of image regions that influence a classifier's decisions, but they predominantly focus on identifying regions wit
While unmanned aerial vehicles (UAVs) offer wide-area, high-altitude coverage for anomaly detection, they face challenges such as dynamic viewpoints, scale variations, and complex scenes. Existing datasets and methods, mainly designed for fixed ground-level views, struggle to adapt to these conditio…
The emphasis on no-reference image quality assessment has often overshadowed the significance of Full-Reference Image Quality Assessment (FR-IQA), which generally better reflects human contrastive perception mechanism. However, FRIQA presents challenges in obtaining content-aligned reference images.…
Benefiting from large-scale pre-training of text-video pairs, current text-to-video (T2V) diffusion models can generate high-quality videos from the text description. Besides, given some reference images or videos, the parameter-efficient fine-tuning method, i.e. LoRA, can generate high-quality cust…
Some encoder inputs such as conversation histories are frequently extended with short additional inputs like new responses. However, to obtain the real-time encoding of the extended input, existing Transformer-based encoders like BERT have to encode the whole extended input again without utilizing t…
Deep unfolding networks (DUNs) have made significant progress in MRI reconstruction, successfully tackling the problem of prolonged imaging time. However, the ill-conditioned nature of MRI reconstruction often causes slow convergence in iterative optimization, potentially compromising the performanc…
2D-3D cross-dimensional registration for spinal surgery navigation, which aims to achieve real-time visual navigation of preoperative 3D vertebrae based on intraoperative 2D fluoroscopy images, faces significant challenges due to semantic and dimensional gaps. Traditional 2D-3D registration methods…
Model-based networks have shown convincing performance in MRI reconstruction. However, the unrolled cascades within the networks are constrained to solely obtain information from the preceding counterpart, resulting in potential error accumulation. Moreover, the linear structure fails to address the…
In accelerated MRI reconstruction problem, directly recovering all the missing k-space data from undersampled measurements is highly ill-posed and often leads to suboptimal performance. To address the problem, we propose a novel deep unfolding network (DUN) with subsampling decomposition (SD) based…
The rapid advancement of generative models has significantly improved the quality of generated images. Meanwhile, it challenges information authenticity and credibility. Current generated image detection methods based on large-scale pre-trained multimodal models have achieved impressive results. Alt…
The combination of CT and MRI can provide more accurate images of lesions, yielding a significantly higher diagnostic value compared to single-modality pathological images. However, in CT-MRI fusion, preserving the gray-scale distribution of the source image while avoiding ‘detail halos’ poses a cha…
In this paper, we addressed facial aesthetic enhancement (FAE). Although existing methods have made great progress, the beautified images generated by them are highly prone to poor beautification, which limits their application to real-world scenes. To tackle this problem, we proposed a new method c…
Versatile Video Coding (VVC) now supports Screen Content Coding (SCC) by integrating two efficient coding modes: Intra Block Copy (IBC) and Palette (PLT). However, the numerous modes and the Quad-Tree Plus Multi-Type Tree (QTMT) structure inherent to VVC contribute to a very high coding complexity.…
Focus stacking is a technique in computational photography, and it synthesizes a single all-in-focus image from different focal plane images. It is difficult for previous works to produce a high-quality all-in-focus image that meets two goals: high-fidelity to its source images and good visual effec…
"Artistic images typically contain the unique creative styles of artists. However, it is easy to transfer an artist’s style to arbitrary target images using style transfer techniques. To protect styles, some researchers use adversarial attacks to safeguard artists’ artistic style images. Prior metho…
Sparse Coding (SC) and Convolution Sparse Coding (CSC) are two widely studied sparse methods in computer vision and signal processing. SC encodes the image patches independently, however fails to utilize the correlation among them. CSC adopts a convolution operator to connect the overlapping patches…
Due to multi-layer encoding and Inter-layer prediction, Spatial Scalable High-Efficiency Video Coding (SSHVC) has extremely high coding complexity. It is very crucial to improve its coding speed so as to promote widespread and cost-effective SSHVC applications. In this paper, we have proposed a nove…
For learning-based binary descriptors, the binarization process has not been well addressed. The reason is that the binarization blocks gradient back-propagation. Existing learning-based binary descriptors learn real-valued output, and then it is converted to binary descriptors by their proposed bin…
Semi-supervised learning is a promising method for medical image segmentation under limited annotation. However, the model cognitive bias impairs the segmentation performance, especially for edge regions. Furthermore, current mainstream semi-supervised medical image segmentation (SSMIS) methods lack…
For image local forgery detection, the existing methods require a large amount of labeled data for training, and most of them cannot detect multiple types of forgery simultaneously.

"The widespread of generative models have called into question the authenticity of many things on the web. In this situation, the task of image forensics is urgent. The existing methods examine generated images and claim a forgery by detecting visual artifacts or invisible patterns, resulting in gen…
In this paper, we introduce a two-level attention schema, Poolingformer, for long document modeling. Its first level uses a smaller sliding window pattern to aggregate information from neighbors. Its second level employs a larger window to increase receptive fields with pooling attention to reduce b…
Workplace communication (e.g. email, chat, etc.) is a central part of enterprise productivity. Healthy conversations are crucial for creating an inclusive environment and maintaining harmony in an organization.
