Mean , 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 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 ...
متن کاملEmpirical likelihood ratio test for median and mean residual lifetime.
Prompted by several recent papers on the inference on median and mean residual life time, we note that the testing involving the mean or median residual life function in censored survival data can be obtained by an easy application of the general empirical likelihood ratio test. This approach has several advantages: (1) There is no need to estimate the variance/covariance at all, which may beco...
متن کاملThe Usefulness of Mean and Median Frequencies in Electromyography Analysis
Rich useful information can be obtained from the muscles and researchers can use such information in a wide class of clinical and engineering applications by measuring surface electromyography (EMG) signals (Merletti & Parker, 2004). Normally, EMG signals are acquired by surface electrodes that are placed on the skin superimposed on the targeted muscle. In order to use the EMG signal as a diagn...
