Abstract

With the aim of identifying a suitable image transformation technique for medical images of different sizes and different modalities, different transform-based compression methods have been experimented and compared. A novel preprocessing technique for capturing the symmetry in a continuous set of medical images has also been used. A set of 240 test images including magnetic resonance imaging (MRI) and computed tomography (CT) of different sizes was selected. The lossy compression ...
