Modern multi-dimensional imaging in radiology yields much more information than the naked eye can appreciate. As a result, errors and variations in interpretations are currently the weakest aspect of clinical imaging. Computerized image analysis may provide solutions for ensuring the quality of medical image interpretation by yielding exhaustive, comprehensive and reproducible analysis of imaging features that are difficult to recognize with the naked eye.
We develop computational models of multi-dimensional morphological properties of biomedical tissue. Riesz wavelets and machine learning algorithms are used to learn the organization of image scales and directions that is specific to a given biomedical tissue type. The models obtained can be “steered” analytically to enable rotation-covariant image analysis. While most rotation-invariant approaches discard precious information about image directions, rotation-covariant analysis enables modeling the local organization of image directions independently from their global orientation. Although already being important in 2D images, this becomes crucial to adequately leverage directional image information in 3D images.
