Airway resistance measured by the interrupter technique: expiration or inspiration, mean or median?
The measurement of airway resistance by the interrupter technique (Rint) needs standardization. Should measurements be made be during the expiratory or inspiratory phase of tidal breathing? In reported studies, the measurement of Rint has been calculated as the median or mean of a small number of values, is there an important difference? Subjects were 2.5-5.0 yrs (median 4.0 yrs) who had previo...
متن کاملMean , median and mode ̄ ltering of images
If a two-dimensional image is simpli ed by repeatedly replacing its values with the mean in an in nitesimal neighbourhood, it evolves according to the di¬usion equation Lt = Lxx + Lyy (subscripts denote di¬erentiation). This equation can alternatively be written in gauge coordinates as Lt = Lvv +Lww, where the v-direction is tangent to the isophote and the w-direction is along the gradient. T...
متن کاملMean – Median Filtering For Impulsive Noise Removal
Abstrak –The objective of this paper is a new MeanMedian filtering for denoising extremely corrupted images by impulsive noise. Whenever an image is converted from one form to another, some of degradation occurs at the output. Improvement in the quality of these degraded images can be achieved by the application of Restoration and /or Enhancement techniques. Noise removing is one of the categor...
متن کاملEdge Preservation of Enhanced Fuzzy Median Mean Filter Using Decision Based Median Filter
Image noise refers to random variations in the basic characteristics of image like brightness, intensity or color difference. These variations are not present in the image which is captured but may occur due to environmental conditions like sensor temperature or due to circuit of the scanner or other similar issues. Basically noise means unwanted signals in the image. Various filters have been ...
متن کاملNote on Qualitative Robustness of Multivariate Sample Mean and Median
It is known that the robustness properties of estimators depend on the choice of a metric in the space of distributions.We introduce a version of Hampel’s qualitative robustness that takes into account the√n-asymptotic normality of estimators in R, and examine such robustness of two standard location estimators in R. For this purpose, we use certain combination of the Kantorovich and Zolotarev ...
