Traditional patch-based and group-based sparse representation methods often struggle with visual artifacts and over-smoothing, limiting their effectiveness. To address these challenges, we propose a novel multi-scale morphological patch-based and group-based sparse representation learning approach for image inpainting. Our method enhances image inpainting by integrating morphological patch-based sparse representation (M-PSR) learning using k-singular value decomposition (k-SVD) and group-based sparse representation using principal component analysis (PCA) to construct adaptive dictionaries for improved reconstruction accuracy. Additionally, we employ the alternating direction method of multipliers (ADMM) to optimize the integration of morphological patch and group based sparse representations, enhancing restoration quality. Extensive experiments on various degraded images demonstrate that our approach outperforms state-of-the-art methods in terms of the peak signal-to-noise ratio (PSNR) and the structural similarity index measure (SSIM). The proposed method effectively reconstructs images corrupted by missing pixels, scratches, and text inlays, achieving superior structural coherence and perceptual quality. This work contributes a robust and efficient solution for image inpainting, offering significant advances in sparse modeling and morphological image processing.</div></div>","PeriodicalId":49521,"journal":{"name":"Signal Processing-Image Communication","volume":"138 ","pages":"Article 117341"},"PeriodicalIF":3.4,"publicationDate":"2025-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144070742","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address these issues, we propose an expression transformation method for anime-style images. In order to enhance the control effect of discrete emoticon tags, a mapping network is proposed to map them to high-dimensional control information, which is then injected into the network multiple times during transformation. Additionally, for better maintaining the anime face identity information while transforming, an integrated attention mask mechanism is introduced to enable the network's expression control to focus on the expression-related features, while avoiding affecting the unrelated features.

In this paper, to address the limitations of existing methods, we introduce an innovative and effective method for enhancing uncontrolled lighting images through adaptive structural compensation. Firstly, a joint filtering algorithm for illumination estimation is developed to effectively mitigate texture, edge and noise interference during illumination estimation. Secondly, we developed a multi-scale illumination estimation algorithm for the purpose of constructing a structural compensation map. This map is then used to control brightness compensation for different areas of the image.

Oracle bone inscription data includes rubbings, handwriting, and photos. Currently, most detection methods primarily focus on rubbings and rely on large-scale annotated datasets. However, it is necessary to detect oracle bone inscriptions on both handwriting and photo domains in practical applications. Additionally, annotating handwriting and photos is time-consuming and requires expert knowledge. An effective solution is to directly transfer the knowledge learned from the existing public dataset to the unlabeled target domain. However, the domain shift between domains heavily degrades the performance of this solution. To alleviate this problem and based on the characteristics of different domains of oracle bone, in this paper, we propose an information disentanglement method for the Unsupervised Domain Adaptive (UDA) OBIs detection to improve the detection performance of OBIs in both handwriting and photos. Specifically, we construct an image content encoder and a style encoder module to decouple the oracle bone image information. Then, a reconstruction decoder is constructed to reconstruct the source domain image guided by the target domain image information to reduce the shift between domains. To demonstrate the effectiveness of our method, we constructed an OBI detection benchmark that contains three domains: rubbing, handwriting, and photo. Extensive experiments verified the effectiveness and generality of our method on domain adaptive OBIs detection.

To overcome this limitation, we propose to use an auxiliary captioning step to enhance the image feature, where the image feature is fused with the text feature of the captioning output. In this way, the captioning output feature, sharing similar space distribution with candidate texts, can provide high-level semantic information to facilitate locating the significant content in an image. To optimize the auxiliary captioning output, we introduce a new metric, Caption-to-Text (C2T), representing the retrieval performance between the auxiliary captioning output and the ground-truth matching texts. By integrating our C2T score as a reward in our image captioning reinforcement learning framework, our image captioning model can generate more suitable sentences for the auxiliary image–text matching.

This requires finding new ways to exploit side information in reducing the transmitted rate and improving the quality of the decoded frames. This paper proposes improving DVC by exploiting image enhancement post-processing at the decoder. In this way, we can either improve the quality of the decoded frames for a given rate or reduce the number of transmitted bits for the same quality and hence reduce the complexity of the encoder. To do this, we used a conditional generative adversarial network (cGAN) to restore more of the details discarded by quantization, with the help of side information. We also evaluated numerous existing deep learning-based enhancement methods for DVC and compared them to our proposed model. The results show a reduction in the number of DVC coding operations by 46 % and an improvement in rate-distortion performance and subjective visual quality.

Achieving complementarity between the image contours and textural details is challenging between the infrared image and the visible image. With the intention of addressing the challenge of poor quality of infrared and visible light fusion images under low light conditions, a novel unsupervised fusion method for infrared and visible image under low_light condition (referred to as UFIVL) is presented in this paper. Specifically, the proposed method effectively enhances the low-light regions of visible light images while reducing noise. To incorporate style features of the image into the reconstruction of content features, a sparse-connection dense structure is designed. An adaptive contrast-limited histogram equalization loss function is introduced to improve contrast and brightness in the fused image.
