Parameters estimation is a crucial and challenging component for Frequency-Hopping (FH) communication. Time-frequency analysis is a valid signal processing tool to estimate parameters of FH signal. However, the existing Time-Frequency analysis methods have several shortcomings such as weak suppression noise interference and feeble concentration of Time-Frequency, resulting in inaccurate parameter...
Accurate stereo matching is still challenging in case of weakly textured areas, discontinuities, and occlusions. Besides, occlusion recovery is often regarded as a subordinate problem and simply handled. To obtain dense high-accuracy depth maps, this letter proposes an efficient multistep disparity refinement framework with occlusion handling. The framework is implemented by classifying the outliers...
Multichannel fast QR decomposition recursive least-squares (MC-FQRD-RLS) algorithms are well known for their good numerical properties and low computational complexity. There are tow distinct ways to obtain the expended input vector, sequential-type method, and block-type one. The latter one, despite exhibiting a higher computational burden as compared to the former one, has some attractive features,...
