This paper details a complete hardware and software system designed to aid in the visual inspection and structural condition monitoring of railway tunnels. The system consists of two main components; an image acquisition system for data collection and an image processing software package for data analysis. The image acquisition system consists of an array of cameras with overlapping fields of view,...
This paper presents an extended algorithm for Real-time Compressive Tracking using Cosine Similarity Metric for object tracking. The method utilises a weighted multi-frame cosine similarity metric with the ground truth bounding box and a recently computed target bounding box. In comparison to the original algorithm it is capable of handling fast motion with a greater degree of accuracy. The proposed...
In this paper we present a fast implementation of an automatic non-photorealistic image processing technique which transforms an input image frame of a video stream into a non-photorealistic abstracted cartoon stylised render. The approach presented utilises a fast cosine integral image method to create a separable bilateral filtering stage which operates in constant time. This is subsequently put...
The explosion of multimedia applications within embedded devices has ensured that Image Processing and Machine Vision has now become a mainstream subject within most Computer Science and Electronic Engineering curricula. Yet often there exists a disconnection between the rapid prototyping tools that are taught within the laboratory to demonstrate concepts and those that are used for actual deployment...
An SFP transceiver with integrated OTDR is used with a commercial Ethernet network termination unit and the OTDR functionality evaluated. We show length measurement readings within 90 m of those obtained from a dedicated commercial OTDR tester. The use of OTDR can reduce network downtime by quick reliable location of faults.
