Abstract
Optical coherence tomography (OCT) is an emerging optical imaging modality with high resolution and non-invasive, which plays an important role in applications such as material detection and disease diagnosis, especially for ophthalmic retinal diseases such as age-related macular degeneration, diabetic macular edema and choroidal neovascularization. However, since OCT utilizes the coherent interference of light, the generated image is inevitably affected by speckle noise, which blurs the structural information of the image such as layer structure and lesion point, and the low-quality OCT image makes its subsequent application become difficult. To solve this problem, an OCT image denoising fusion based on discrete wavelet transform and spatial domain feature weighting is proposed in this paper. Extensibility experiments show that the proposed algorithm can better remove noise and retain its precise structural information compared with several state-of-the-art OCT image denoising algorithms.
期刊介绍:
The journal (under its former title Optica Acta) was founded in 1953 - some years before the advent of the laser - as an international journal of optics. Since then optical research has changed greatly; fresh areas of inquiry have been explored, different techniques have been employed and the range of application has greatly increased. The journal has continued to reflect these advances as part of its steadily widening scope.
Journal of Modern Optics aims to publish original and timely contributions to optical knowledge from educational institutions, government establishments and industrial R&D groups world-wide. The whole field of classical and quantum optics is covered. Papers may deal with the applications of fundamentals of modern optics, considering both experimental and theoretical aspects of contemporary research. In addition to regular papers, there are topical and tutorial reviews, and special issues on highlighted areas.
All manuscript submissions are subject to initial appraisal by the Editor, and, if found suitable for further consideration, to peer review by independent, anonymous expert referees.
General topics covered include:
• Optical and photonic materials (inc. metamaterials)
• Plasmonics and nanophotonics
• Quantum optics (inc. quantum information)
• Optical instrumentation and technology (inc. detectors, metrology, sensors, lasers)
• Coherence, propagation, polarization and manipulation (classical optics)
• Scattering and holography (diffractive optics)
• Optical fibres and optical communications (inc. integrated optics, amplifiers)
• Vision science and applications
• Medical and biomedical optics
• Nonlinear and ultrafast optics (inc. harmonic generation, multiphoton spectroscopy)
• Imaging and Image processing
