Scheduling Continuous-Time Kalman Filters [PDF]
IEEE Transactions on Automatic Control, 2011 A set of N independent Gaussian linear time-in variant systems is observed by M sensors whose task is to provide a steady-state causal estimate minimizing the mean-square error on the system states, subject to additional measurement costs. The sensors can switch between systems instantaneously, and there are additional resource constraints, for example

Clogging Time of a Filter [PDF]
Physical Review Letters, 2000 We study the time until a filter becomes clogged due to the trapping of suspended particles as they pass through a porous medium. This trapping progressively impedes and eventually stops the flow of the carrier fluid. We develop a simple description for the pore geometry and the motion of the suspended particles which, together with extreme-value ...

Learning long-term filter banks for audio source separation and audio scene classification
EURASIP Journal on Audio, Speech, and Music Processing, 2018 ■■■ Filter banks on short-time Fourier transform (STFT) spectrogram have long been studied to analyze and process audios. The frameshift in STFT procedure determines the temporal resolution.

Median Filtering in Constant Time [PDF]
IEEE Transactions on Image Processing, 2007 The median filter is one of the basic building blocks in many image processing situations. However, its use has long been hampered by its algorithmic complexity of O (r) in the kernel radius. With the trend toward larger images and proportionally larger filter kernels, the need for a more efficient median filtering algorithm becomes pressing.

Broadband Frost Adaptive Array Antenna with a Farrow Delay Filter
International Journal of Antennas and Propagation, 2018 In a broadband adaptive array antenna with a space-time filter, a delay filter is required before digital beamforming when the Frost algorithm is used to obtain the weight vector.

Time-Range Adaptive Focusing Method Based on APC and Iterative Adaptive Radon-Fourier Transform
Remote Sensing, 2022 In conventional radar signal processing, the cascade of pulse compression (i.e., matched filter) and Radon-Fourier transform (RFT) can extract the estimated scattering coefficient of the target in the range-velocity dimension through long-time coherent ...

URBAN VEGETATION MAPPING BASED ON THE HJ-1 NDVI RECONSTRCTION [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2016 HJ-1A/B NDVI (HJ NDVI) time-series data possess relatively high spatio-temporal resolution which is significant for the research on urban areas. However, its application is hindered by noise resulting from the restrictions of imaging quality and limits ...
