The quality of the displayed image during minimal-invasive operations (endoscopy) may be low due to highlights and water vapor in front of the camera lens. In some cases, image processing like temporal color vector median filtering may enhance the visual quality of the images [8]. In this contribution we present a new technique of ordering, filtering and re-ordering of color image pixels that i...

Introduction: The accuracy of analyzing Functional MRI (fMRI) data is usually decreases in the presence of noise and artifact sources. A common solution in for analyzing fMRI data having high noise is to use suitable preprocessing methods with the aim of data denoising. Some effects of preprocessing methods on the parametric methods such as general linear model (GLM) have previously been evalua...
