14Machine Vision Approach for Automating Vegetation Detection on Railway TracksJournal of Intelligent Systems 22 (2): 179-196. 2013.The presence of vegetation on railway tracks threatens track safety and longevity. However, vegetation inspections in Sweden are currently being carried out manually. Manually inspecting vegetation is very slow and time consuming. Maintaining an even quality standard is also very difficult. A machine vision-based approach is therefore proposed to emulate the visual abilities of the human inspector. Work aimed at detecting vegetation on railway tracks has been split into two main phases. The firs…Read more

16Something Old, Something New, Something Borrowed, Something Blue Part 2: From Frankenstein to Battlefield Drones; A Perspective on Machine EthicsJournal of Intelligent Systems 22 (1): 1-7. 2013.. Intelligent systems are reaching the point where they can take very significant decisions on behalf of humans and society. The moral and ethical impact of such systems needs to be taken very seriously, both internally and externally in respect of such systems. Although some work into defining and systematizing machine ethics has begun, a great deal of work remains to be done and many research questions remain open.

Something Old, Something New, Something Borrowed, Something Blue: Part 3 – An Elephant Never ForgetsJournal of Intelligent Systems 26 (3). 2017.Forgetting is an oft-forgotten art. Many artificial intelligence systems deliver good performance when first implemented; however, as the contextual environment changes, they become out of date and their performance degrades. Learning new knowledge is part of the solution, but forgetting outdated facts and information is a vital part of the process of renewal. However, forgetting proves to be a surprisingly difficult concept to either understand or implement. Much of AI is based on analogies wit…Read more

9Something Old, Something New, Something Borrowed, Something Blue Part 1: Alan Turing, Hypercomputation, Adam Smith and Next Generation Intelligent SystemsJournal of Intelligent Systems 21 (4): 325-330. 2012.. In this article intelligent systems are placed in the context of accelerated Turing machines. Although such machines are not currently a reality, the very real gains in computing power made over previous decades require us to continually reevaluate the potential of intelligent systems. The economic theories of Adam Smith provide us with a useful insight into this question.

13Segmentation of Fingerprint Images Based on Bi-level Combination of Global and Local ProcessingJournal of Intelligent Systems 21 (2): 97-120. 2012.. This paper presents a new approach to segment low quality fingerprint images which are collected by low quality fingerprint readers. Images collected using such readers are easy to collect but difficult to segment. The proposed approach is based on combining global and local processing to achieve segmentation of fingerprint images. On the global level, the fingerprint is located and extracted from the rest of the image by using a global thresholding followed by dilation and edge detection of t…Read more

15Automatically Detecting the Number of Logs on a Timber TruckJournal of Intelligent Systems 22 (4): 417-435. 2013.This article describes a method of automatically detecting, counting and classifying logs on a timber truck using a photograph. An image-processing algorithm is developed to process the photograph to calculate an estimate of the number of logs present and their respective diameters. The algorithm uses color information in multiple color spaces as well as geometrical operators to segment the image and extract the relevant information. This information enables the sawmill to better plan internal l…Read more
