Image texture analysis

Image texture analysis

Motivation

Image texture is a rich source of information about the objects visible in the image. This applies especially to biomedical images. Image texture visualized by means of various medical imaging modalities represents the properties of organs and tissues. Texture parameters reflect the physiological properties of such structures. This enables segmentation of organs, detection of lesions and an assessment of pathological changes degree. The significance of texture analysis for aided imaging diagnostics has been demonstrated for all kinds of imaging modalities, including computed tomography (CT), Magnetic Resonance Imaging (MRI), ultrasound (USG) and optical imaging.

  • Research directions

    Many textures show some anisotropy. Image intensity or color patterns are aligned and have clear orientations in 2D space. Texture direction analysis finds many biomedical applications. We are conducting research in order to develop accurate methods for detection of textural directionality. Main contributor is Marcin Kociołek

    In cooperation with scientists from many research institutions and physicians, we conduct research on various applications of image texture analysis in supporting medical imaging diagnostics. Main contributors are Piotr Szczypiński, Michał Strzelecki Andrzej Materka, Artur Klepaczko, Marek Kociński and Marcin Kociołek
