ELD exhibits significantly better backward error than other methods (Fig.2c), which can be attributed to the inconsistent landmarks found by the other methods. Although all models show better performance in forward error than backward error, ELD displays marginally worse performance in forward error...
Subsequent multivariate statistics and visualization proceed mainly as in the landmark-based methods. The combination provides a range of complementary filters, from high pass to low pass, for effects on outline shape in grouped studies. The low-pass version is based on the spectrum of the spline...
4.1.1 Landmark-based methods In these methods, the nose tip and eye corner are the key landmarks, while the landmarks from cheek, mouth, and other regions easily affected by expression variations are rarely utilized for recognition. Lu et al. (2004) selected the inner eye, outer eye, ...
Our method is AOA-based (angle of arrival) and it is called A2L (angle to landmark). Compared, via simulations, to previous methods such as APS and AHLoS, A2L considerably increases the number of located nodes with accurate precision while using a smaller node degree. 展开 ...
This inappropriate use-case highlights both the importance of precisely locating true landmarks and the difficulty of forcing such landmark-based methods to register landmark-deficient objects. The Computational Morphometry Toolkit9 (CMTK; http://www.nitrc.org/projects/cmtk) includes a landmark-...
Presents an approach to vision-based mobile robot localization. In an attempt to capitalize on the benefits of both image and landmark-based methods, we describe a method that combines their strengths. Images are encoded as a set of visual features called landmarks. Potential landmarks are de...
It will be applied to the existing shape analysis framework to detect clusters or subgroups of similarly-shaped objects.;This thesis will discuss some methods that have been developed in the field of landmark-based statistical shape analysis, and apply these methods to an example three-dimensional...
Fast and Consistent Matching for Landmark-Based Place Recognition Severe condition changes make visual place recognition a difficult task for robotics applications. Landmark-based methods that combine local image regions ... Q Liu,F Duan - 《Journal of Intelligent & Robotic Systems》 被引量: 0发表...
Landmark methods for forms without landmarks: morphometrics of group differences in outline shape. Face detection, pose estimation, and landmark localization in the wild Face Detection, Pose Estimation, and Landmark Localization in the Wild
We first compare the proposed method with some state-of-the-art methods. Then the Gabor-based methods and the LBP-based methods are also compared with the proposed method. Last, we give the role of each step of the proposed method. In Conclusion In this paper, we propose an improved ...
