Shape from Texture

Home page of Angeline M. Loh

I am a postdoc researcher living in the beautiful city of Perth, Western Australia. I completed a PhD at the University of Western Australia in the School of Computer Science and Software Engineering. My project was in Computer Vision, primarily working with Shape-from-Texture. I was supervised by Dr Peter Kovesi and Prof. Robyn Owens.



Shape from Texture

Shape from Texture is the problem of estimating the structure of the world using texture.

Ocean texture Brick texture Pear texture

For example, given a picture of the ocean, how do you estimate the height of the camera above the water using the appearance of the waves? Can a computer guess the shape of a building using information from the brick texture? Can we guess the shape of a pear using the dots on its surface? Textures provide a powerful shape cue to humans. The ability of computers to mimic this behaviour would be useful in a myriad of applications such as autonomous navigation, object recognition and movie-making.

I am now working as a research fellow in the Lab for Genetic Epidemiology at the Western Australian Institute for Medical Research (WAIMR).
