Adaptive filtering algorithms are pervasive throughout signal processing and have had a material impact on wide variety of domains including audio processing, telecommunications, biomedical sensing, astrophysics cosmology, seismology, many more. filters typically operate via specialized online, iterative optimization methods such as least-mean squares or recursive least aim to process signals i...

This paper proposes a new bilateral control scheme to ensure both transparency and robust stability under unknown constant time delay in stiff environment. Furthermore, this method guaranties suitable performance and robust stability when transition occurs between soft and stiff environments. This framework is composed of an adaptive sliding mode controller and an adaptive impedance controller,...

This study compares the effectiveness of various image enhancement filters for improving the perceived visibility of coloured digital natural images for people with visual impairment. Generic filters were compared with Peli's adaptive enhancement and adaptive thresholding and custom-devised filters based on each subject's contrast sensitivity loss. Subjects with low vision made within filter ra...
