Webb7 apr. 2024 · The experimental results show that our proposed method achieved a peak signal-to-noise ratio (PSNR) of 16.5342 dB and a structural similarity index (SSIM) of 0.6385 on an RGB-NIR (Red, Green, Blue-Near Infrared) testing dataset, representing a 5% and 13% improvement over the original CGAN network, respectively. Webb12 apr. 2024 · In the process of downsampling, the detection of small infrared targets encounters problems such as imaging area, missing texture features, and disappearance of targets. This study proposes a local contrast attention guide network (LCAGNet), which implements and uses a SPD-CSP Resblock (i.e., CSPResblock based on sub-pixel …

Webb24 maj 2024 · Also, it is a wireless communication medium so there is no need of digging and spreading wires. 5. Infrared waves are used in TV remotes, mobile phones, personal computers. Radio waves are used in AM and FM radios, and cordless phones. Microwaves are used in mobile phones communication and television distribution. WebbThe simulated infrared countermeasure data was used as the training set and test set of the network, and the network was retrained. The test results show that the precision of the YOLOV2-D network is higher than 99%, which is 7.5% higher than YOLOV2. The recall rate of the YOLOV2-D network is higher than 96%, which is 2% higher than … shiprock animal shelter

PANs connect devices within the range of an individual and are no larger than about 10 meters (m). Because PANs operate in such limited areas of space, most are wireless and provide short-range connectivity with infrared technology. In general, objects emit infrared radiation across a spectrum of wavelengths, but sometimes only a limited region of the spectrum is of interest because sensors usually collect radiation only within a specific bandwidth. Thermal infrared radiation also has a maximum emission wavelength, which is inversely proportional to the absolute temperature of object, in accordance with Wien's d… questions to ask product manager in interview
