For scenarios where the type of structural break in a time series is unknown, this paper proposes modified ratio-type test statistic to enable effective online monitoring breaks, while circumventing estimation long-term variance. Under specific assumptions, we rigorously derive asymptotic distribution under null hypothesis and establish its consistency alternative hypothesis. In cases both variance mean breaks coexist, introduce refined mixed-break procedure based on consistent breakpoints....
This paper proposes a Tchebichef moment (TM)-based image definition assessment (IDA) method that employs the difference in logarithmic spectra (DLS). To avoid influence of original image, essential element point spread function (PSF) is extracted from DLS to characterize IDA uniquely. The amplification PSF spot radius defocus amount micro-imaging system enhances featural differences among DLSs, thereby improving sensitivity amount. with an obvious geometric feature variation described by TM...
Photometric stereo reconstructs surface shape with intricate details by analyzing the light propagation process and has attracted wide range of applications such as industrial measurement. However, presence non-Lambertian reflections on real-world scenarios poses a significant challenge to normal estimation methods. Most existing approaches aim achieve reasonably accurate results filtering observations through employing iterative frameworks. Based these, this study introduces novel method...
In industrial production, hexagonal screws are widely used as fasteners, and it is crucial to have fast accurate inspection of these for automated screwing processes. However, this remains a challenge due various factors such environmental distractions, lighting, shadows, screw positioning. To address this, the Line Perspective Hexagonal Screw Detection (LPHD) algorithm has been proposed in paper, which introduces four innovative techniques: canny value, base, perspective correction, double...
Multiscale analysis and characterizations of metallic surface topographies is a crucial task in advanced manufacturing precision engineering. In this paper, we present multiscale measurement technique based on photometric stereo for accurately reconstructing at different scales. Our system employs zoom lens LED illuminators, providing the flexibility to adjust scale. To ensure efficiency accuracy during scale transition, fast light source calibration method using Lambertian sphere proposed...
