Wavelet-like filter banks for multi-dimensional and multi-resolution signal processing
… various multi-dimensional and multi-resolution signal processing operations to be performed efficiently. Many efforts, including theoretical investigation, numerical simulation and application study were made to achieve the project aim. The multi-resolution theory was investigated to provide the …

Noise and Degradation Reduction for Signal and Image Processing via Non-adaptive Convolution Filtering
… are present, specifically in the fields of signal and image processing. The effect of image processing on target detection is of significant interest because noise and degradations can greatly reduce the effectiveness of detection algorithms, due to the presence of high intensity noise which …

An approach for the separation of voices in composite musical signals
… is fundamental to most music. Ensemble musical signals consist of superpositions of multiple distinct sonic events which may or may not be synchronized in time, frequency, and/or amplitude. Once the distinct events are combined and recorded in a storage medium, e.g., a digital recording, the …

Novel Architectures for Trace Buffer Design to facilitate Post-Silicon Validation and Test
… the ability to observe as many relevant internal signal values as possible during debug. To do so, trace buffers have been proposed for enhancing the observability of internal signals during post-silicon debug. Trace Buffers are used to trace (record the values of) the internal signals in …

Bayesian approaches to time-frequency inverse problems
… media such as gas, liquid or solid, audio signals are better defined and understood by the way their spectral composition evolves over time. Characterising the dynamics of these hidden spectral components—rather than their raw waveform—is crucial in a wide range of practical applications …

Study of Multiple ASE-Noise Effects and A Filtering Solution For Soliton Propagation Through Optical Fibers
… has been performed on the use of soliton signals in optical communication systems. This potentially allows an optical signal to propagate along a fiber line with minimal need for signal restoration through electrical conversion. Various sources of noise can cause a soliton signal to become …
