It is necessary for the system such as the robotics vision and the monitoring camera to detect the motion of the object and recognize the target in real time. However, this is difficult in conventional image processing systems constructed with a charge coupled device (CCD) camera and Neumann-type computer since information processing in this setup is accomplished in a time-sequential way. On th...

study on polsar target detection essentially requires the cattering information and polarimetric statistical data. theoretical analysis shows that some terms of the second order scattering matrices such as coherence and covariance matrix clearly show the differences between nonsymmetrical man-made objects and natural clatters which being reflection symmetric. using the model derived from these ...

background and objectives: hbv dna monitoring is important in management of chronic viral hepatitis b infection. hbv dna measurements are carried out over period of months to years. so the analytical system must be stable and reproducible. the aim of this study was to determine the performance characteristics and to plan a statistical quality control system of a laboratory-developed real-time q...

Automated construction site supervision systems are critical for reducing accident risks. We propose a helmet detection system with low-altitude remote sensing by UAVs in this paper to automate the of helmet-wearing workers overcome limitations most efforts that rely on ground surveillance cameras and improve efficiency safety supervision. The proposed has following key aspects. (1) an approach...

This paper explores the concept of a Forward Scattering Radar (FSR) system with a rotational transmitter for target detection and localization. Most of the research and development in FSR used a fixed dedicated transmitter; therefore, the detection of stationary and slow moving target is very difficult. By rotating the transmitter, the received signals at the receiver contain extra information ...

This paper presented a novel method to detect the signal of the instantaneous infrared target based on the Finite Element Analysis (FEA). The radiation energy produced by flame infrared target was divided to finite element section. Studied the distribution of the unit area energy of flame in the detection system and the calculation method of flame radiation obtained by the photosensitive surfac...

Background and Objective: The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is still an ongoing challenge in health system worldwide. Molecular detection methods including reverse transcription loop-mediated isothermal amplification (RT-LAMP) can help cutting off the transmission chain of the virus. In this study, prompt setting up of the RT-LAMP assays were investigated using ge...
