A new decoder is proposed to decode the (23, 12, 7) binary Golay-code up to five errors. It is based on the algorithm that can correct up to four errors for the (24, 12, 8) extended Golay-code proposed by Lin et al., thereby achieving the soft decoding in the real sense for the Golay-code. For a weight-2 or weight-3 error pattern decoded by the hard decoder for correcting up to three errors, on...

In order to reduce excessive fertiliser application, a non-destructive method of spectral data acquisition using spectroradiometer with wavelet analysis was explored determine the level nutrients in oil palm leaves. analysis, de-noising (WD) can be applied remove background noises and other disturbances such as scattered light that may affect results data. Therefore, this study aims evaluate be...

A rapid and nondestructive tea classification method is of great significance in today’s research. This study uses fluorescence hyperspectral technology machine learning to distinguish Oolong by analyzing the spectral features wavelength ranging from 475 1100 nm. The data are preprocessed multivariate scattering correction (MSC) standard normal variable (SNV), which can effectively reduce impac...

Impact damage to apples is one of the most crucial quality factors and needs be detected in postharvest sorting processes. In this study, impact ‘Red Fuji’ apple fruit was investigated quantitatively by hyperspectral imaging technology. A total 240 samples were prepared with six groups for different degrees. The technique based on near-infrared (NIR) spectrometry range 900–1700 nm used measure ...

at first, ground-based circular strip-map synthetic aperture radar (gb-csmsar) and its capabilities is introduced and the received signal model, 2-d frequency spectrum and the azimuth and range resolutions are derived and compared with the linear motion strip-map sar resolutions. because of the stability of the path and speed of antenna in gb-csmsar a frequency domain imaging algorithm is sugge...

Cone-beam computed tomography (CBCT) images suffer from poor image quality, in a large part due to contamination from scattered X-rays. In this work, a Monte Carlo (MC)-based iterative scatter correction algorithm was implemented on measured phantom data acquired from a clinical on-board CBCT scanner. An efficient EGSnrc user code (egs_cbct) was used to transport photons through an uncorrected ...

introduction: one of the most important parameters in x-ray ct imaging is the noise induced by detected scattered radiation. the detected scattered radiation is completely dependent on the scanner geometry as well as size, shape and material of the scanned object. the magnitude and spatial distribution of the scattered radiation in x-ray ct should be quantified for development of robust scatter...
