In order to achieve robust segmentation results under noise interference, a hybrid active contour model for the segmentation of targets in images using local feature information and global information is proposed. Based on the concept of orientation columns in the primary visual cortex, orientation column filters are defined, which can effectively extract local feature information with noise robustness. Then a global term with noise robustness is defined, and the adaptive weight matrix is adopted to combine the two to construct a complete signed pressure force (SPF) function. Several experiments demonstrate that the proposed algorithm performs more accurately and robustly on noisy infrared images segmentation compared to typical algorithms.KEYWORDS: Infrared image segmentationactive contour modelorientation column filterssigned pressure force functionadaptive weight matrix Disclosure statementNo potential conflict of interest was reported by the author(s).Additional informationFundingNational Natural Science Foundation of China [62001234, 62201260]; Natural Science Foundation of Jiangsu Province [BK20200487]; Fundamental Research Funds for the Central Universities [JSGP202102]; Equipment Pre-research Weapon Industry Application Innovation Project [627010402]; Equipment Pre-research Key Laboratory Fund Project [6142604210501].","PeriodicalId":16426,"journal":{"name":"Journal of Modern Optics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135011612","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the THz spectrum of most molecules in aqueous solution is completely different from that of solid molecules, and they have strong absorption characteristics for THz waves. In this study, a microfluidic chip with very low THz wave absorption was designed, and the THz transmission spectra of food-additive sodium hexametaphosphate solution and sodium pyrophosphate solution were measured using THz time domain spectroscopy (THz-TDS). The results show that the THz transmission spectral intensity of the two sodium salt solutions increases with the increase of solution concentration, which is due to the influence of ion hydration process on hydrogen bonds between water molecules and changes the absorption of THz waves by water. This method lays a foundation for further study of the THz characteristics of electrolyte solutions.KEYWORDS: Terahertzmicrofluidic chipTHz-TDS systemsodium salt solutionsodium hexametaphosphatesodium pyrophosphate Disclosure statementNo potential conflict of interest was reported by the author(s).Additional informationFundingThis work was supported by the National Natural Science Foundation of China (NSFC 61575131).","PeriodicalId":16426,"journal":{"name":"Journal of Modern Optics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135011469","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

But if the projector is slightly defocused, the binary fringes after defocusing still contain high-order harmonics compared with the ideal sinusoidal fringes, so the phase error caused by the nonlinear response is not negligible. In this paper, two models are proposed to calculate and compensate phase error, which include a double-precision iterative compensation model (DPICM) and a dual-domain iterative compensation model (DDICM). These two models obtain accurate phase errors by fusing the phases at different precision and domains. DPICM is composed of the double precision method and the improved iterative algorithm, and DDICM consists of the dual-domain method and the improved iterative algorithm. This improved iterative algorithm is used to compensate phase error, which can improve phase accuracy.

The GAF algorithm is derived from a scattering field based on integral equations and the computational electromagnetic method. Specifically, our use of the method of moments has enabled us to tackle the problem of analytically computing the shadowing and masking on a rough surface by taking practical factors such as wavelength, surface contour, polarization, material, rms, and so on into consideration.

Based on vector Debye-Wolf diffraction integral and a new fusion optimization algorithm, an improved method is described for efficiently designing the most widely-used concentric multi-belt pupil filters. The main advantage of this method is that it actively selects the minimum belt width and the total belt number for facilitating low-cost batch processing. Pupil filters for visible and near-infrared bands have been separately designed for improving the spatial resolution of optical imaging and ultrafast laser processing. The method has been experimentally demonstrated for suppressing the optical focal spot.

In this method, to avoid the loss of effective detail information, the mode of fixed attenuation parameter setting is changed into two stages of self-adaptation setting: the first attenuation parameter is defined as the convolution of filtered pixels in the window of interest, the second attenuation parameter is defined as the noise standard deviation of each pixel after filtering in the first stage. Moreover, the Pearson coefficient expression is redefined to get a more accurate similarity evaluation, and the algorithm's operational efficiency has been improved using cross-correlation functions and fast Fourier transform.
