In the advertising and media industries, image editing often involves multiple manipulation techniques to meet creative and technical requirements. Detecting tampered regions is crucial in scenarios like legal disputes or media integrity assessments. However, existing forensic methods often target single manipulation types or treat all manipulations as one, and many deep learning approaches lack flexibility in frequency and edge extraction, limiting their effectiveness. To address these challenges, this paper proposes an ALL-IN-ONE framework for comprehensive image forensic analysis, which adopts a divide-and-conquer strategy for multi-manipulation image classification and localization. Specifically, we introduce a Multi-Frequency Band Extraction Module (MBEM) to capture richer artifact information in the frequency domain. This is complemented by an Attention Window-based Fusion Module, which fuses same-frequency features across different scales and enhances the discriminative features more effectively. To improve the localization of copy-move manipulation, we design a Copy-Move Accurate Detection Module (CADM), which leverages the visual consistency between source and target regions. Furthermore, we propose a Precise Edge Generator (PEG) as part of the Edge-Guided Progressive Fine-Tune Module (EPFM), which can generate more accurate edge to enhance edge localization. To address the issue of insufficient labeled data, we construct a publicly available dataset, the Multi-Manipulation Image Dataset (MMID), consisting of 2,000 multi-manipulation images, each containing at least two types of forgeries. Extensive experiments are conducted, comparing our method with state-of-the-art approaches on MMID, as well as on single-manipulation datasets such as CASIA, CoMoFoD, and NIST. The results demonstrate that MMID is effective for training discriminative models and validate that our proposed method significantly outperforms existing approaches in terms of accuracy and robustness for simultaneous forgery localization and manipulation classification.

Most methods address occluded pedestrian Re-Identification (Re-ID) by employing external auxiliary models in the feature output stage of the backbone network to locate visible appearance areas. Nevertheless, these approaches suffer from issues such as occlusion information diffusion and imprecise masks generated by external models, indicating the need for further exploration in the decoupling of pedestrian features from occlusion information. In light of these challenges, we propose an innovative algorithm called Pose-Skeleton guided Cross-attention Representation fusion (PSCR) method. Firstly, we introduce the Visible Appearance Region Attention (VARA) model designed to leverage pose information for guiding the backbone network in effectively distinguishing between occlusion information and pedestrian features at the intermediate layer. By employing a suppression strategy, the model is able to effectively suppress occlusion interference and alleviate the diffusion of occlusion information. Next, to achieve precise localization of pedestrian-specific semantic regions, a groundbreaking Skeletal Area Modeling (SAM) is proposed. Leveraging the principles of mathematical modeling and capitalizing on the efficacy of human keypoint confidence, this module generates finely-grained masks for local skeleton regions and extracts an exhaustive set of local features. Lastly, under the constraints imposed by spatial attention masks, a cross-attention mechanism is employed to fuse the features acquired from the previous two steps with local features. This fusion process results in the generation of enhanced local features that seamlessly integrate aligning high-level semantic information. Extensive experimentation demonstrates that the proposed algorithm exhibits notable performance advancements when compared to existing methodologies.

Abstract With the goal of solving the problem of feature extractors lacking strong supervision training and insufficient time information concerning single‐sequence model learning, a hierarchical sequence memory network with a multi‐level iterative optimisation strategy is proposed for continuous sign language recognition. This method uses the spatial‐temporal fusion convolution network (STFC‐Net) to extract the spatial‐temporal information of RGB and Optical flow video frames to obtain the multi‐modal visual features of a sign language video. Then, in order to enhance the temporal relationships of visual feature maps, the hierarchical memory sequence network is used to capture local utterance features and global context dependencies across time dimensions to obtain sequence features. Finally, the decoder decodes the final sentence sequence. In order to enhance the feature extractor, the authors adopted a multi‐level iterative optimisation strategy to fine‐tune STFC‐Net and the utterance feature extractor. The experimental results on the RWTH‐Phoenix‐Weather multi‐signer 2014 dataset and the Chinese sign language dataset show the effectiveness and superiority of this method.

Despite the recent advances of face age transformation in the age accuracy of face synthesis or the integrity of identity information, only age used as the condition of aging is insufficient to depict the real aging process. In this work, we propose a novel GAN-based identity-preserving aging method with Multi-scale attention and Multi-attribution fusion (named M2aging) to address this problem. In particular, we design a High-fidelity Multi-scale Attention(HiMA) module to capture minute and local features at different scales, improving the model's identity-preserving ability. In addition, a Multi-attribution Fusion Modulator (MFM) is proposed by fusing age, gender, and race attributions to control the aging process, which enhances attribution preservation without introducing any additional classifiers and training losses. Experimental results show the proposed M2aging outperforms other SOTA techniques in terms of identity preservation and accurate age conversion. The ablation experiments manifest that HiMA can effectively heighten the fidelity of the transformed images, and MFM can effectively control the aging process according to age, gender, and race.

Retrieving an occluded pedestrian remains a challenging problem in person re-identification (re-id). Most existing methods utilize external detectors to disentangle the visible body parts. However, these methods are unstable due to domain bias and consume numerous computing resources. In this paper, we propose a novel and lightweight Part-based Representation Enhancement (PRE) network for occluded re-id that takes full advantages of the local correlations to aggregate distinctive information for local features without relying on auxiliary detectors. First, according to the information qualities of different body parts, we design a reasonable partition strategy to obtain the local features. Next, a Partial Relationship Aggregation (PRA) module is developed to self-mine the visibility of the body and construct a correlation matrix for collecting the information related to pre-defined classes. Following this, we propose an Inter-part Omnibearing Fusion (IOF) module that leverages the occlusion-suppressed class features to enhance the distinctiveness of the local features via feature completion and reverse fusion strategies. During the testing phase, the global and reconstructed local features are concatenated together for re-id without a complex visible region matching algorithm. Extensive experiments on occluded, partial, and holistic re-id benchmarks demonstrate the superiority of PRE over state-of-the-art methods in terms of accuracy and model complexity.

In copy-move forgery, the illumination and contrast of tampered and genuine regions are highly consistent, which poses a greater challenge in copy-move forgery detection. In this article, an end-to-end neural network is proposed based on adaptive attention and residual refinement network (AR-Net). Specifically, position and channel attention features are fused by the adaptive attention mechanism to fully capture context information and enrich the representation of features. Second, deep matching is adopted to compute the self-correlation between feature maps, and atrous spatial pyramid pooling fuses the scaled correlation maps to generate the coarse mask. Finally, the coarse mask is optimized through the residual refinement module, which retains the structure of object boundaries. Extensive experiments, evaluated on CASIAII, COVERAGE, and CoMoFoD datasets, demonstrate that the AR-Net has superior performance than state-of-the-art algorithms and can locate tampered and corresponding genuine regions at the pixel level. In addition, AR-Net has high robustness on postprocessing operations, such as noise, blur, and JPEG recompression.
