Variance Image Filter
This paper describes an intensity image filter for computing the variance of pixel values contained within a neighborhood centered at each input pixel. The output image contains the calculated variance at each input pixel location. Variance calculations can [...]

Voxel Value Ratio Variance Image Registration Metric for the Insight Toolkit
This document describes a cost function, or metric, for use in image registration using the Insight Toolkit. The RatioVarianceImageToImageMetric class implements a metric which is calculated from the variance of the ratios of voxel values of the moving and [...]

Liver Tumor segmentation in CT images using probabilistic
Liver tumors segmentation is an important prerequisite for planning of surgical interventions. For clinical applicability, the segmentation approach must be able to cope with the high variation in shape and gray-value appearance of the liver. We present a [...]
