Gaussian pyramid reduction method for the extraction of pathological structures of the aorta

Sobotnicka E., Sobotnicki A., Jeżewski J.

Vol. 26

37--44

An analysis of the biomedical image in one scale may result in the loss of information contained in the image during an analysis in a different scale. This issue can be solved by an analysis performed simultaneously in all scales, which can be done through the application of the pyramid reduction method. The pyramid makes it possible to obtain images at various levels of detail, including significant information. The paper discusses the method of processing biomedical images of the aorta with the use of the pyramid reduction method, as well as the way in which the results can be used in the segmentation process. The Gaussian pyramid reduction method was used for pyramid representation, whereas the segmentation process was performed with the split and merge method.
