Facial contour extraction method of underground personnel
Gong-kuang zidonghua, 2015 For low identification ratio of attendance system of coal mine caused by difficult facial contour extraction of underground personnel, a facial contour extraction method was proposed based on active contour model (Snake model) and active shape model (ASM)

Cage Active Contours for image warping and morphing
EURASIP Journal on Image and Video Processing, 2018 Cage Active Contours (CACs) have shown to be a framework for segmenting connected objects using a new class of parametric region-based active contours.

Statistical shape theory for activity modeling [PDF]
2003 International Conference on Multimedia and Expo. ICME '03. Proceedings (Cat. No.03TH8698), 2003 Monitoring activities in a certain region from video data is an important surveillance problem. The goal is to learn the pattern of normal activities and detect unusual ones by identifying activities that deviate appreciably from the typical ones. We propose an approach using statistical shape theory based on the shape model of D.G. Kendall et al. (see

Computer modeling reveals modalities to actuate mutable, active matter
Nature Communications, 2022 Catalytic reactions on flexible sheets generate fluid flows that transform the shape of the sheet, which in turn modifies the flow. These complex interactions make computer models vital for designing and harnessing these feedback loops to create soft ...

Robust Evolution Method of Active Contour Models and Application in Segmentation of Image Sequence
Journal of Electrical and Computer Engineering, 2018 Active contour models are widely used in image segmentation. In order to obtain ideal object boundary, researchers utilize various information to define new models for image segmentation. However, the models could not meet all scenes of image.

Geometric models to explore mechanisms of dynamic shape change in skeletal muscle [PDF]
Royal Society Open Science, 2018 Skeletal muscle bulges when it contracts. These three-dimensional (3D) dynamic shape changes play an important role in muscle performance by altering the range of fascicle velocities over which a muscle operates. However traditional muscle models are one-

IEEE Access, 2019 Glaucoma is an eye disease which is one of the most common causes of blindness. Accurate optic disc (OD) and optic cup (OC) segmentation play a critical role for detecting glaucoma. Considering that the existing approaches can't effectively integrate the

Active Shape Models-Their Training and Application
Computer Vision and Image Understanding, 1995 Model-based vision is firmly established as a robust approach to recognizing and locating known rigid objects in the presence of noise, clutter, and occlusion. It is more problematic to apply model-based methods to images of objects whose appearance can vary, though a number of approaches based on the use of flexible templates have been proposed.

A weighting strategy for Active Shape Models [PDF]
2017 IEEE International Conference on Image Processing (ICIP), 2017 Active Shape Models (ASM) are an iterative segmentation technique to find a landmark-based contour of an object. In each iteration, a least-squares fit of a plausible shape to some detected target landmarks is determined. Finding these targets is a critical step: some landmarks are more reliably detected than others, and some landmarks may not be ...
