Using digital image analysis for assessing the quality of wheat and barley

- Armstrong, Bruce

  • Authors: Armstrong, Bruce
  • Date: 2004
  • Type: Text , Thesis , Masters
  • Full Text:
  • Description: This thesis explores the issues involved in developing a relatively low-cost digital imaging analysis (DIA) system fot the quality assessment of wheat and barley using commonly available equipment. It also explores the capability of such a system to provide rapid and accurate assessments.

Colour image annotation using hybrid intelligent techniques for image retrieval

  • Description: This paper presents a novel technique for colour image annotation based on neural networks and fuzzy logic. Neural network is proposed for classifying the images based on their contents and fuzzy logic is proposed for interpreting the content of an image in terms of natural language. One of the main aspects of this research is to avoid re-training of the neural networks by training the content of the image. Neural network is not trained on database of images; therefore image can be added or deleted from image database without affecting the training. The proposed hybrid technique is tested on real world colour image dataset and promising results are obtained. © 2012 IEEE.

  • Description: Fracture behaviour of clay soils is an important area in soil mechanics that needs further development. Currently, there is no test method to determine fracture properties of clay soils during desiccation. The past work has been mostly on the use of fracture toughness as applicable to linear elastic fracture mechanics using external loading of specimens. However, importance of considering likely plasticity in fracture propagation, especially with soft soils, has been highlighted. J integral is an important parameter in elasto-plastic fracture mechanics, which accounts for the change in potential energy with fracture propagation. This paper presents an innovative test method to evaluate the fracture behaviour, in particular to determine J integral, as applicable to desiccating soils. The challenging task of calculating strains and stresses of slurry clays has been dealt with using an image-analysis technique. Starting from the fundamentals of fracture mechanics, J integral is expressed as a summation of several line integrals. The major advantage of the new method is its suitability for wet or slurry soils for which load tests are impossible. Copyright © 2012 by ASTM International.

  • Description: Public transport is designed to move people efficiently and affordably around their communities. Millions of people internationally with disabilities rely on public transport every day to connect them to services, work, educational and social events. Many of these people attempt to board public transport using a powered mobility aid (such as an electric wheelchair, mobility scooter, or gopher) and this number is expected to rise as the population ages. Evidence suggests that many people have difficulty getting their powered mobility aids on and off public transport vehicles, and consumers, vendors and the health care-professionals involved in recommending mobility aids have no way of knowing which powered mobility aids are compatible with existing public transport configurations. The purpose of this paper is to demonstrate how existing 3D technologies and software can be applied to solve this real world problem using the example of buses. This proof-of-principle paper describes the process of scanning buses and powered mobility aids in 3D, together with descriptions of the prototype software to undertake the computerised process, to determine the compatibility of powered mobility aids for access on buses. Feasibility is then demonstrated using an example of one bus and one powered mobility aid. This paper is of interest to researchers wishing to examine the application of 3D technologies, health care providers and consumers who select powered mobility aids, as well as transport policy makers and conveyance commissioners who can access 3D data to optimise transport network accessibility for all community members. © 2018
