A multichannel filter for TV signal processing [PDF]

IEEE Transactions on Consumer Electronics, 1996
A multichannel filtering approach is introduced. The framework is used to correct impulsive noise and other image impairments in TV signal transmission. The principles behind the new filter are explained in detail. Simulation results indicate that the new filter offers some flexibility and has excellent performance.

Guided mesh normal filtering [PDF]

, 2015
The joint bilateral filter is a variant of the standard bilateral filter, where the range kernel is evaluated using a guidance signal instead of the original signal. It has been successfully applied to various image processing problems, where it provides

Method of Range Ambiguity Suppression Combining Sparse Reconstruction and Matched Filter

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2022
Synthetic aperture radar (SAR) images are often affected by range ambiguity due to antenna sidelobe characteristics and pulse operating mechanism. The work of range ambiguity suppression focuses on both SAR system design and signal processing. On the one

Nonlinear filtering for LIDAR signal processing

Mathematical Problems in Engineering, 1996
LIDAR (Laser Integrated Radar) is an engineering problem of great practical importance in environmental monitoring sciences. Signal processing for LIDAR applications involves highly nonlinear models and consequently nonlinear filtering. Optimal nonlinear filters, however, are practically unrealizable.

A Frequency-Correcting Method for a Vortex Flow Sensor Signal Based on a Central Tendency

Sensors, 2020
A vortex flow meter employs a sensor based on the piezoelectric vibration principle to realize vortex signal acquisition, and therefore the measurement results are susceptible to vibration noise.

On the Shift Operator, Graph Frequency, and Optimal Filtering in Graph Signal Processing [PDF]

IEEE Transactions on Signal Processing, 2015
Defining a sound shift operator for graph signals, similar to the shift operator in classical signal processing, is a crucial problem in graph signal processing (GSP), since almost all operations, such as filtering, transformation, prediction, are ...
