This work explores techniques for sonar sensor fusion in the context of environmental feature detection and identification for navigation tasks. By detecting common features in indoor environments and using them as landmarks, a robot can navigate reliably, recovering its pose when necessary. Preliminary results on a multiple hypothesis testing procedure for feature localization and identificati...

A technical report on Feature detection and implementing the Speeded-Up Robust Features(SURF)

The research reported here addresses the problem of detecting and tracking independently moving objects from a moving observer in real time, using corners as object tokens. Local image-plane constraints are employed to solve the correspondence problem removing the need for a 3D motion model. The approach relaxes the restriciive static-world assumption conventionally made, and is therefore capab...

Colour assessment of pigmented skin lesions are essential for the diagnosis of malignant melanoma. However, visual interpretation of colour is subjective and prone to error. Computer programs can provide support to clinicians to overcome this subjectivity. So far, methods for colour analysis of this nature have utilised statistical classification models. This paper puts forward an alternative f...

Feature detection, extraction and representation are important steps for multimedia processing. Extracting ideal features that reflect the intrinsic and core content of the images in a complete form is still a challenging problem in computer vision systems. However, less research time has been given to this problem in the last few decades. In this paper, our review shows development made in ima...

The Blizzard Challenge is an independent evaluation of synthetic speech systems. This paper describes the Jess system, one of the participants in the Blizzard Challenge 2007. One of the unique features of the Jess system is the use of articulatoryacoustic feature detection to ensure a higher degree of acoustic consistency at joins. To make results comparable with the system presented last year ...

A tractor gearbox test rig has been used to collect signals from different types of bearing faults. For vibration monitoring accelerometers have been used to obtain vibration data. For fuel-injectors a bearing checker has been used in order to collect acoustic data. One class Self Organizing Maps (OCSOM) are used for detecting faults when exposed to actual data from the system representing a ye...

Do vowel-contingent selective adaptation effects for place of articulation depend on vowel identity, or on the particular formant frequencies used? An experiment is reported here which tested the adaptation effects of consonants with exactly the same formant transitions before different diphthongs. In this experiment, the phonetic identity of the vowel and the formant frequencies of the consona...

Fast, accurate, autonomous robot navigation is essential for landing and roving on planets. For landing, particularly, computing speed matters. Navigation algorithms calculate feature descriptors in stereo pairs as the basis of visual odometry and obstacle avoidance. Feature detection is understood, but requires hundred-fold speed-up which is not achievable on conventional lander and rover comp...
