Improving Frequency-Aware Image Restoration Techniques for Real-World Degradations /

By Ayub, Nooh . . 74p. , Image quality often deteriorates under challenging weather conditions such as haze and snow, which create significant barriers for vision-driven intelligent systems, including autonomous vehicles, real-time surveillance, and remote sensing applications. To address this pressing challenge, we propose a comprehensive deep learning framework capable of simultaneously handling both image dehazing and desnowing in a unified manner. At the core of our design lies the NAFXT block—an advanced extension of NAFNet—that integrates Dynamic Tanh (DyT) normalization in place of the traditional layer normalization. Notably, DyT normalization is introduced for the first time in this context as a more effective alternative, offering superior adaptability compared to standard layer normalization within convolutional neural network (CNN) architectures, particularly the NAFNet framework. While layer normalization primarily ensures stable training and faster convergence, DyT normalization enhances the model’s ability to capture richer and more expressive feature representations. As a result, the proposed framework achieves better restoration quality while requiring fewer training epochs than several cutting-edge methods. In addition, we incorporate the Multi-Branch Dynamic Selective Frequency (MDSF) and Multi-Branch Compact Selective Frequency (MCSF) modules, originally introduced in FSNet, to promote frequency-aware global feature learning across multiple scales. The network further adopts a multi-input and multi-output encoder–decoder structure, where both NAFXT and residual blocks are systematically integrated at every stage to progressively refine the restored outputs. Extensive experiments performed on three widely recognized benchmark datasets confirm that our method consistently surpasses state-of-the-art approaches, achieving higher quantitative scores and delivering visually sharper, clearer, and more natural results in both dehazing and desnowing tasks. 30cm.

Advanced nanocarriers for skin diseases /

By Khan, Rida Khalid. . 68p. , The development and evaluation of an advanced nanocarrier hydrogel system designed to address the major barriers in diabetic wound healing, specifically targeting chronic inflammation, oxidative stress, bacterial infection, and impaired angiogenesis. This therapeutic system integrates cerium oxide nanoparticles (CeO₂), metal-organic frameworks (MOFs), and a chitosan-gelatin hydrogel platform to create a multifunctional wound dressing. CeO₂ nanoparticles provide strong antioxidant and antibacterial activity, MOFs enable controlled drug release and add antimicrobial properties, while the chitosan-gelatin hydrogel ensures biocompatibility, moisture retention, and accelerated tissue repair. Comprehensive characterization, including Raman spectroscopy, FTIR, UV-Vis, EDX analysis, and optical microscopy, confirmed successful synthesis, structural integrity, and the presence of desired functional groups. Biological assays demonstrated superior antibacterial and antibiofilm performance of the CeZn-Gel composite against E. coli and S. aureus, surpassing individual system components and controls. The integrated approach not only enhances wound healing outcomes but also reduces infection and inflammation, with significant potential for improving patient quality of life in chronic wound care. Future work will focus on optimizing formulation and advancing toward clinical testing for broader therapeutic impact. 30cm.
