Image contrast enhancement uses the object intensity transformation function to maximize amount of information enhance an image. In this paper, image problem is regarded as optimization problem, and particle swarm algorithm used obtain optimal solution. First, improved proposed. algorithm, individual optimization, local global are adjust particle’s flight direction. topology induce comparison communication between particles. The sparse penalty term in speed update formula added sparsity size...
Abstract This paper presents a simple DFT-based golden section searching algorithm (DGSSA) for the single tone frequency estimation. Because of truncation and discreteness in signal samples, Fast Fourier Transform (FFT) Discrete (DFT) are inevitable to cause spectrum leakage fence effect which lead low estimation accuracy. method can improve accuracy under conditions signal-to-noise ratio ( SNR ) resolution. firstly uses three FFT samples determine scope, then – besides estimated values...
Wide dynamic range is an important index of the resonator fiber optic gyro (RFOG). The related to parameters ring (FRR). After adopting appropriate parameters, resonant curve a FRR and synchronous demodulated are measured. Based on closed-loop frequency locking technique, wide obtained, while linearity guaranteed. experiment's results show that ±480 deg/s with less than 1% nonlinearity, bias stability 0.04 over 2000 s. This Letter demonstrates scheme for RFOG range.
The accurate detection and localization of polyps during endoscopic examinations are critical for early disease diagnosis cancer prevention. However, the presence artifacts noise, along with high similarity between surrounding tissues in color, shape, texture complicates polyp video frames. To tackle these challenges, we deployed multivariate regression analysis to refine model introduced a Noise-Suppressing Perception Network (NSPNet) designed enhanced performance. NSPNet leverages wavelet...
The storage capacity, speed and the dimension of device is restricted in impact test environment. In order to meet high data transmission, logging reliability requirements high-g environment measurement, paper presents design a miniature high-performance memory module.The module using high-speed serial transceiver as input interface, through FPGA achieve real-time processing store into large capacity chip. circuit merely 33mm×33mm but rate can be up 60Mbyte/s, 8Gbyte. Ensuring continuous...
The inspection of railway fasteners to assess their clamping force can be used evaluate the looseness and improve safety. Although there are various methods for inspecting fasteners, is still a need non-contact, fast without installing additional devices on fasteners. In this study, system that uses digital fringe projection technology measure 3D topography fastener was developed. This inspects through series algorithms, including point cloud denoising, coarse registration based feature...
Cables play an important role in transmitting energy and information. In this article, order to obtain the S-parameters of special twisted pair cable with rectangular connectors, a de-embedding method transmission matrix is proposed deal two adapters ends cable. According frequency-dependent RLGC(f) model, characteristics are extracted frequency range 10 MHz 200 through conventional modified methods respectively. The frequency-domain analysis shows that inherent capacity can decrease errors...
