The measurement of shape and deformation of objects has many applications in various areas of computer vision. One of the most important applications of measuring deformation is in experimental mechanics, where it has been used to determine or assess mechanical properties of objects. The information gathered about the mechanical properties of objects can provide input data to inform or construct computational models, which can then be used to describe or predict the behaviour of the object.

Human body tissues have a complex behaviour that varies significantly across different individuals, depending on factors such as age, gender, and ethnicity. The precision and robustness of the techniques used to measure deformations are thus essential to address the needs of bioengineering applications. However, prior to my PhD thesis, existing techniques had shortcomings and limitations that prevented their effective use in many applications, including bioengineering applications. 

In this presentation, I will explain how the limitations of existing methods were addressed during my PhD by developing a toolbox for precise and robust deformation measurements. Our developed methods demonstrated significant improvements over existing state-of-the-art algorithms. Some of the outcomes of this thesis include several publications, two patents (filed by UniServices Limited), and three commercialisation awards. 

The high precision and robustness of our methods also enable their use in many applications that were not previously possible or feasible. I will briefly describe some of these new opportunities in my presentation.
