The method combines NMF and NSST to extract the common and structural information of images, resulting in clearer, more natural, and accurate image fusion results. Specifically, we use NMF to decompose multiple input images and obtain their common and individual parts. Through the decomposition of NMF, the original image can be represented as a product of a non-negative matrix V , which contains the pixel values of the original image and several columns representing the basis matrix of the image. In our method, the common part corresponds to the information shared by the images, while the individual part corresponds to the individual features of the images. Then, we use NSST to decompose the common and individual parts to obtain image information at different scales and orientations. NSST is a multiscale analysis method based on shearlet transform, which can preserve the structural information of the image and suppress the pseudo-Gibbs phenomenon. Finally, we fuse the common and individual parts processed by NSST separately to obtain an output image that integrates the details and features of the image. This fusion method can handle images of different types, sizes, and resolutions well and performs well in processing complex situations. To verify the performance of the proposed method, we conducted experiments on different datasets and compared them with other commonly used image fusion methods. The experimental results show that the proposed method achieves good fusion effects. Therefore, the method proposed in this article has a wide range of application prospects in the field of image fusion.","PeriodicalId":13408,"journal":{"name":"Iet Optoelectronics","volume":"28 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87092243","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In recent years, there have been many researches on neural networks using optical hardware. The Mach–Zehnder interferometer (MZI) and micro-ring resonator (MRR) are commonly used as optical devices to realise linear operation units in optical neural networks (ONN). MZI has the advantages of simple fabrication, high sensitivity, and easy integration, which has attracted the attention of researchers. We summarise the implementation methods of ONN matrix multiplication based on MZI, the implementation methods of non-linear activation, and the on-chip training methods. We first summarise the researches on matrix multiplication of ONN based on MZI. Three kinds of MZI grid decomposition methods, Fast Fourier Transform (FFT) grid structures, and the corresponding derivation processes are introduced, respectively. Then, several experimental implementations of ONN based on MZI are summarised, and the characteristics of optical processors fabricated in these references are analysed. Finally, the realisation methods of non-linear activation and on-chip training of silicon ONN are introduced, respectively.</p>","PeriodicalId":13408,"journal":{"name":"Iet Optoelectronics","volume":"17 1","pages":"1-11"},"PeriodicalIF":1.6,"publicationDate":"2022-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/ote2.12086","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43985237","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
