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)

Active Contour with a Tangential Component [PDF]
Journal of Mathematical Imaging and Vision, 2014 Conventional edge-based active contours often require the normal component of an edge indicator function on the optimal contours to approximate zero, while the tangential component can still be significant. In real images, the full gradients of the edge indicator function along the object boundaries are often small.

The Potential of Active Contour Models in Extracting Road Edges from Mobile Laser Scanning Data
Infrastructures, 2017 Active contour models present a robust segmentation approach, which makes efficient use of specific information about objects in the input data rather than processing all of the data.

A Novel Active Contour Model Guided by Global and Local Signed Energy-Based Pressure Force
IEEE Access, 2020 Active contour models (ACMs) have been widely applied in the field of image segmentation. However, it is still very challenging to construct an efficient ACM to segment images with intensity inhomogeneity.

IEEE Transactions on Pattern Analysis and Machine Intelligence, 1999 A method for deforming curves in a given image to a desired position in a second image is introduced in this paper. The algorithm is based on deforming the first image toward the second one via a partial Differential equation, while tracking the deformation of the curves of interest in the first image with an additional, coupled, partial Differential ...

Higher Order Active Contours [PDF]
International Journal of Computer Vision, 2006 We introduce a new class of active contour models that hold great promise for region and shape modelling, and we apply a special case of these models to the extraction of road networks from satellite and aerial imagery. The new models are arbitrary polynomial functionals on the space of boundaries, and thus greatly generalize the linear functionals ...
