Two-stream convolutional networks have shown strong performance in video action recognition tasks. The key idea is to learn spatiotemporal features by fusing convolutional networks spatially and temporally. However, it remains unclear how to model the correlations between the spatial and temporal structures at multiple abstraction levels. First, the spatial stream tends to fail if two videos share...
Infrared Guidance Hardware-in-loop Simulation technology has great significance In the aerospace. Further research of the simulation system had been made by many institutions and scientists both at home and abroad. In this text, based on the infrared theory and the optical configuration of infrared hardware-in-loop simulation system, the equivalent model of target and background infrared radiation...
The research takes Radarsat-2 multi-polarization radar images and ALOS multi-spectrum optical images for example, through the information filtering and extraction methods such as information quantity statistics and correlation matrix, we obtain the cognition of the spectral characteristics and detection performance of each polarization mode radar image, and select the optimal data for fusion and classification...
