In this paper, we propose a hybrid similarity measure for 2D-3D image registration that is a weighted combination of an intensitybased image similarity measure and a point-based measure incorporating a single fiducial marker. We evaluate its accuracy and robustness using gold-standard clinical spine image data. The use of one fiducial marker substantially improves registration accuracy and robu...
ABSTRACT Regarding cellular immunity function and macrophage system in tuberculosis infection control and also tuberculosis high spread in Gilan province and as many studies about tuberculosis has done in chronic and acute progressive process. This study was examined thirty persons smear positive with clinical symptoms and recognition infections expert before Treatment. Tuberculosis patients ...
We present a model for estimating a probabilistic map of ecological habitats using species presence/absence data and environmental covariate data observed at the sites where species presence data were collected. The model is notable because it treats spatially varying patterns of species distributions as the principle defining characteristic of habitats. The model also permits inference about t...
This paper summarizes and compares techniques for detecting and identifying markers in the context of computer vision. Existing approaches use correlation, digital, or topological methods for marker identification. The comparison points out that all marker processing algorithms, which employ sophisticated digital codes are more robust and reliable. Existing bit representation schemes for these ...
Since Stein’s original proposal in 1962, a series of papers have constructed confidence regions of smaller volume than the standard spheres for the mean vector of a multivariate normal distribution. A general approach to this problem is developed here, and used to calculate a lower bound on the attainable volume. Bayes and fiducial methods are involved in the calculation. Scheffe-type problems ...
Abstract: In this paper we extend Fisher’s fiducial argument and obtain a generalized fiducial recipe that greatly expands the applicability of fiducial ideas. We do this assuming as little structure as possible. We demonstrate this recipe on many examples of varying complexity. We investigate, by simulation and by theoretical considerations, some properties of the statistical procedures derive...
Developments in mobile healthcare result in wide use of mobile phones to acquire, store or analyse mobile users’ biosignals, such as the electrocardiogram (ECG). These activities have motivated global research in designing new QRS-complex detectors and delineators for single-lead ECG signals. This paper examines a QRS detection and delineation algorithm based on a Euclideandistance calculation ...
Shoulder Complex Joint Location: an In-vivo Study Using Intracortical Pins, Imaging and Skin Markers
Joint centre locations can be determined using imaging, bony landmarks and functional methods. Using intracortical pins, CT-scan and skin markers, sternoclavicular (SC), acromioclavicular (AC) and glenohumeral (GH) joints were located and compared for four participants. The use of skin and pin markers led to inconsistent results for SC and AC joints, while bony landmarks and CT based locations ...
