Dynamic Features for Segmental Speech Recognition
(IEEE, 1996)Speech models and features that emphasise the dynamic aspects of speech can provide improved speech recognition. The cepstral time matrix has been established as a successful method of encoding dynamics. The paper extends ... -
Variation of features of interframe dependent HMM for speech recognition
(1998)The effects are explored of using different dynamic features in conjunction with an HMM that permits a dependency on both preceeding and succeeding frames. In particular, features which capture dynamic information are ... -
Multi-Resolution Cepstral Features for Phoneme Recognition Across Speech Sub-Bands
(IEEE, 1998)Multi-resolution sub-band cepstral features strive to exploit discriminative cues in localised regions of the spectral domain by supplementing the full bandwith cepstral features with subband cepstral features derived ... -
Blind Source Separation of Speech in Hardware
(IEEE, 2005)This paper presents preliminary work on a hardware implementation of a source separation algorithm employing time-frequency masking methods. DUET (Degenerate Unmixing Estimation Technique) has previously been shown to ... -
Towards a Hardware Realization of Time-Frequency Source Separation of Speech
(IEEE, 2005)This paper presents preliminary work on a hardware implementation of a source separation algorithm employing time-frequency masking methods. DUET (Degenerate Unmixing Estimation Technique) has previously been shown ... -
Exploiting Voicing Cues for Contrast Enhanced Frequency Shaping of Speech for Impaired Listeners
(IEEE, 2006)This paper investigates the use of voicing information as an additional cue in contrast enhanced frequency shaping (CEFS) of speech to improve perception in the hearing impaired. The presented work builds on an existing ... -
A HMM Framework for Motion based parsing for video from Observational Psychology
(IEEE, 2006)In Psychology it is common to conduct studies involving the observation of humans undertaking some task. The sessions are typically recorded on video and used for subjective visual analysis. The subjective analysis is ... -
Discriminitive Multi-Resolution Sub-Band and Segmental Phonetic Model Combination
(2000)A joint discriminative framework for multi-resolution sub-band HMMs and a hybrid segmental phonetic model is presented which combines independent likelihood scores using class dependent weightings trained to a minimum ... -
Linear and nonlinear optical anisotropy of amorphous oxidized silicon films induced by a network of a pores
(American Physical Society, 2006)By thermal oxidation of initially birefringent porous silicon, highly optically transparent films of porous silicon oxide are produced. These films exhibit strong in-plane birefringence, which is twice as high as that of ... -
Form birefringence of oxidized porous silicon
(American Institute of Physics, 2006)A network of preferentially oriented pores is shown to induce anisotropy of linear and nonlinear optical properties of oxidized porous silicon (OPS) films. Although the x-ray diffraction indicates the presence of amorphous ... -
Electrotunable in-plane one-dimensional photonic structure based on silicon and liquid crystal
(American Institute of Physics, 2007)The model of the electro-optical effect, due to the reorientation of liquid crystal molecules from a pseudoisotropic to a homeotropic state, in a composite photonic structure with a liquid crystal filler, is elaborated. A ... -
Content Controlled Image Representation for Sports Streaming
(Suvisoft, 2005)Content based analysis has traditionally been posed in the context of identifying some material in response to a user query. This paper illustrates that given a content based analysis process that can identify semantic ... -
The linear Monge-Kantorovitch linear colour mapping for example-based colour transfer
(2007)A common task in image editing is to change the colours of a picture to match the desired colour grade of another picture. Finding the correct colour mapping is tricky because it involves numerous interrelated operations, ... -
Localised deflicker of moving images
(2006)Brightness fluctuations in sequences are a typical impairment in archive and modern footage. These fluctuations are mainly temporal but they may also present spatial variations across each individual frame. Current deflicker ... -
Practical Motion Based Video Matting

Electronic slide matching and enhancement of a lecture video
(2007)This paper presents an automatic method to enhance video presentations for distance learning applications. From a material recorded by a fixed, non professional camera, the system matches the slides displayed during the ... -
A new global estimation algorithm and its application to retrieval in sport events
(IEEE, 2001)We propose a novel global motion estimation technique based on weighted gradient and displaced frame difference (DFD) associated with Wiener estimation. Then, we apply this technique to parse events of a high level of ... -
An improved error resilience scheme for highly compressed data
(IEEE, 2002)The coding of highly compressed data streams involves removing as much redundancy from the stream as possible. However, as redundancy is removed, so is the ability of the decoder to recover from error conditions caused by ... -
Joint Audio Visual Retrieval for Tennis Broadcasts,
(IEEE, 2003)In recent years, there has been increasing work in the area of content retrieval for sports. The idea is generally to extract important events or create summaries to allow personalisation of the media stream. While previous ...
