A new sound source separation method has been developed that is robust against individual variability in microphones and acoustic lines. A specific area that has a target sound source was enhanced by using a spatial filter developed by time-frequency masking. However, there is a strong likelihood that the spatial filters will be distorted due to the impact of individual variability in microphon...

Donald G. Bailey Physics Department, Massey University Palmerston North, New Zealand D.G.Bailey @ massey . ac.nz Filtering is often used in image processing to smooth noise, and to enhance or detect features within an image. Images which have regular patterns in the spatial domain have peaks in the frequency domain corresponding to the spatial frequencies of the regular patterns. When processin...

One of the common approaches to specify locations is by indicating their spatial relationships to other, more well-known, locations. This chapter aims at analyzing the feasibility of expressing this kind of spatial relations in subscriptions of Distributed Event-based Systems (DEBSs). On one hand, the spatial relation expressions consist of various location-level abstractions, which have to be ...

We propose a novel fast inverse halftoning technique using a combination of spatial varying filtering and spatial invariant filtering. The proposed algorithm is significantly simpler than most existing algorithms. Without explicit edge region classification, the proposed spatial varying filter is shown to be capable of preserving edges effectively.

This paper describes a novel approach to the spatial filtering of deformation tensor derived maps of shape difference and shape change estimated in multi-subject studies of spatially normalised brain anatomy. We propose a spatial shape filter that combines tensor values locally which fall within regions of similar underlying intensity and therefore tissue. The filter additionally incorporates i...

This paper has two major aims; to show a method for making image deblurring masks from simple Ronchi ruling diffraction gratings, and second, to show a simple means for introducing noise-reducing redundancy into an optical processing system when the processing is a one-dimensional operation, as in the case of deconvolution of a one-dimensionally blurred image. Yu has described a method for intr...

This paper presents a new and efficient approach for optimization and implementation of filter banks e.g. velocity channels, orientation channels and scale spaces. The multi layered structure of a filter network enable a powerful decomposition of complex filters into simple filter components and the intermediary results may contribute to several output nodes. Compared to a direct implementation...

The scalable extension to H.264/AVC defines a coding scheme that organizes data in such a way that starting from a base layer increased spatial, temporal and quality detail can be obtained by the addition of successive information layers. In the case of spatial scalability a fundamental operation is inter-layer prediction which due to the block based nature of the algorithm originates block-edg...
