“…DeCara et al [14] examined 65 patients using this technique and compared the obtained values with the LVEF measurements usiobtained with Simpson's method. Their results confirmed the high correlation between TMAD values and the two-plane standard LVEF measurements [14]. In 2010, Tsang et al [15] examined a group of 118 patients using the TMAD algorithm in relation to LVEF assessment based on magnetic resonance imaging and obtained encouraging results indicating a significant correlation between both measurements.…”

“…This method is also called related tracking method. Product correlation (Prod) [3] [4], differential correlation (MAD) [5] [6], and sequential similarity detection (SSAD) are the three most commonly used correlation tracking algorithms. Because the relevant tracking method does not need image segmentation and feature extraction, it can track the target well in low signal-to-noise ratio images and is suitable for guided missile guidance devices, which is suitable for infrared image target tracking.…”

Abstract. Visual tracking is a hot topic in the field of computer vision, this paper firstly describes the classification and application of visual tracking and highlights the advantages of object tracking based on infrared image by simple comparison. Combined with the research of this technology, tracking technology is divided into five categories, which are named region-based tracking, model-based tracking, activity-based tracking, feature-based tracking, and filteringbased tracking respectively. Finally, based on the characteristics of infrared images, this paper expounds the difficulties in the visual tracking of infrared images and prospects the research prospect of infrared image visual tracking.

“…In the literature, most of the common tracking methods for measuring MAD which depending on the myocardial tissue structure (Storaa et al, 2004;Pan et al, 2001). Measurement of MAD by M-mode echocardiography from apical fourchamber view has been described during recent years as a simple and reliable index for assessment the left ventricular function (Eto et al, 2005;DeCara et al, 2005;Emilsson et al, 2000). MAD was measured using tissue tracking method based on Doppler tissue imaging that allows rapid semi quantitative visual assessment of the systolic distance of tissue motion along the Doppler axis by a graded colour display (Zahid et al, 2013;Ito et al, 2007).…”

Mitral Annular Displacement (MAD) in echocardiography has been described as a variation in mitral annulus position between the enddiastolic and the end-systolic in a complete cardiac cycle. It could be used as a rapid and reproducible method of determining the LV global systolic function and could be an easily detectable index for wall motion abnormalities. In this study, a computational method of MAD was implemented based on the mitral annulus motion tracking at both sides; namely the lateral side and the septal side using 2D-Echocardiographic (2DE) datasets. This method comprises three main processing stages: 2DE dataset preparation, Region Of Interest (ROI) selection and MAD measurements. For each 2DE dataset, MAD was computed as the movement distance toward the LV apex at both sides individually in twoconsecutive frames using the 'Euclidian distance' method. Then, the maximum displacement occurs during a complete cardiac cycle was measured in millimetres (mm) for each side. The overall datasets used are 178 original 2D-echocardiography images in 4-chamber view. The experimental results for MAD measurements were compared with results that obtained by TMQ Advanced technique using QLAB software. The comparative analysis was done qualitatively by visual observation of two expert and the comparison scores show that the proposed method of MAD measurements has high acceptability of 85%. Furthermore, the quantitative analysis of the MAD method is comparable with TMAD measurements by QLAB and there is no significant differences in displacement measurements.
