Although the abundant information in LFIs enables a more immersive experience, it also poses a greater challenge for Light Field Image Quality Assessment (LFIQA), especially when reference information is inaccessible. In this paper, inspired by the holistic visual perception of high-dimensional LFIs and neuroscience studies on the Human Visual System (HVS), we propose a novel Blind Light Field image quality assessment metric by exploring MultiPlane Texture and Multilevel Wavelet Information, abbreviated as MPT-MWI-BLiF. Specifically, considering the texture sensitivity of the secondary visual cortex (V2), we first convert LFIs into multiple individual planes and capture textural variations from these planes. Then, the statistical histogram of textural variations for all planes is calculated as holistic textural variation features. In addition, motivated by the fact that neuronal responses in the visual cortex are frequency-dependent, we simulate this visual perception process by decomposing LFIs into multilevel wavelet subbands with Four-Dimensional Discrete Haar Wavelet Transform (4D-DHWT). After that, the subband geometric features of first-level 4D-DHWT subbands and the coefficient intensity features of second-level 4D-DHWT subbands are computed respectively. Finally, we combine all the extracted quality-aware features and employ the widely-used Support Vector Regression (SVR) to predict the perceptual quality of LFIs. To fully validate the effectiveness of the proposed metric, we perform extensive experiments on five representative LFIQA databases with two cross-validation methods. Experimental results demonstrate the superiority of the proposed metric in quality evaluation, as well as its low time complexity compared to other state-of-the-art metrics.

Since the image degradation process is unknown in real-life scenarios, it is crucial to perform image super resolution in a blind manner. Diffusion models have revolutionized the task of blind image super resolution in view of their powerful capability of producing realistic textures and structures. Design of the condition network is a key factor for diffusion models in providing high image super resolution performances. In this regard, we develop an effective image restoration bank by using a three-stage learning algorithm based on the idea of unsupervised learning, and feed its results, wherein visual artifacts are remarkably suppressed, to the condition network. The use of the unsupervised learning in the design of our image restoration bank guarantees that both diverse contextual information of visual signals, as well as, different degradation operations are considered for the task of blind image super resolution. Further, we guide the feature generation process of the condition network in such a way that the fidelity of the feature tensors produced for the task of image super resolution remains high. The results of extensive experiments show the superiority of our method over the state-of-the-art blind image super resolution schemes in the case of various benchmark datasets.","PeriodicalId":13159,"journal":{"name":"IEEE Transactions on Broadcasting","volume":"71 4","pages":"1048-1064"},"PeriodicalIF":4.8,"publicationDate":"2025-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145766209","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The system utilizes LDM-SFN to enable both wide-area Single Frequency Network (SFN) coverage and localized broadcast/multicast services within a single Radio Frequency (RF) broadcast channel. By combining SFN (core layer) and localcasting (enhanced layer) via Layered Division Multiplexing (LDM), GSL improves spectrum efficiency but faces challenges such as co-channel interference and SFN vs. Localcasting Channel Profile Mismatch (LCPM), which limit localcasting coverage. This paper presents two receiving methods that facilitate LDPC-coded LDM signal reception. Method 1 is the Multiple localcasting signals Iterative Joint Detection and Decoding (IJDD), which can mitigate severe co-channel interference with required Channel Status Information (CSI) of nearby localcasting transmitters. Method 2 is the Constellation Rotated IJDD (CR-IJDD), which can mitigate severe LCPM without CSI. The proposed methods enable decoding of both desired and interfering signals under high SNR conditions, enhancing spectrum reuse. Additionally, an Early Extrinsic Information Exchange for LDPC Iteration Reduction (EEIE-LIR) scheme is introduced to accelerate convergence and reduce receiver complexity. Evaluations based on ATSC 3.0 ModCods demonstrate that the proposed methods significantly improve spectrum efficiency and mitigate the co-channel interferences.

To further enhance the competitiveness of CRC-TBCCs, this paper aims to design low-complexity serial list Viterbi decoders (SLVDs) for them. In the proposed decoder, we first apply regular sectionalization on the original trellis to obtain the sectionalized trellis (ST) and then remove all edges whose log-likelihood ratios (LLRs) are below a given threshold to obtain the edge-reduced ST (E-ST). The resulting decoder is termed E-ST-SLVD. We show that there exists an efficient method to determine the desired threshold for ST. We then analyze the decoding complexity the proposed decoder and the interrelationships among key parameters influencing decoding complexity. We finally present extensive numerical results to show that, with appropriate sectionalization length and threshold, the E-ST-SLVD admits a lower complexity than the original SLVD. Meanwhile, we have compared the decoding complexities of several competitive short-length codes for broadcasting to show the advantage of the proposed decoder.

However, directly applying these methods to screen content (SC) images, which possess distinct characteristics such as sharp edges, repetitive patterns, embedded text and graphics, yields suboptimal results. This paper addresses three key challenges in SC image compression: learning compact latent features, adapting quantization step sizes, and the lack of large SC datasets. To overcome these challenges, we propose a novel compression method that employs a multi-frequency two-stage octave residual block (MToRB) for feature extraction, a cascaded triple-scale feature fusion residual block (CTSFRB) for multi-scale feature integration and a multi-frequency context interaction module (MFCIM) to reduce inter-frequency correlations. Additionally, we introduce an adaptive quantization module that learns scaled uniform noise for each frequency component, enabling flexible control over quantization granularity. Furthermore, we construct a large SC image compression dataset (SDU-SCICD10K), which includes over 10,000 images spanning basic SC images, computer-rendered images, and mixed NS and SC images from both PC and mobile platforms. Experimental results demonstrate that our approach significantly improves SC image compression performance, outperforming traditional standards and state-of-the-art learning-based methods in terms of peak signal-to-noise ratio (PSNR) and multi-scale structural similarity (MS-SSIM).
