Lung Segmentation using Active Shape Model to Detect the Disease from Chest Radiography [PDF]

Journal of Biomedical Physics and Engineering, 2021
Background: Some parametric models are used to diagnose problems of lung segmentation more easily and effectively. Objective: The present study aims to detect lung diseases (nodules and tuberculosis) better using an active shape model (ASM) from chest ...

A Framework of Vertebra Segmentation Using the Active Shape Model-Based Approach [PDF]

International Journal of Biomedical Imaging, 2011
We propose a medical image segmentation approach based on the Active Shape Model theory. We apply this method for cervical vertebra detection. The main advantage of this approach is the application of a statistical model created after a training stage ...

Texture-and-Shape Based Active Contour Model for Insulator Segmentation

IEEE Access, 2019
Insulator segmentation is a critical step for automatic insulator fault diagnosis in high voltage transmission systems. Existing methods fail to segment insulators when they have a low contrast with the surroundings.

3D Active Shape Model Segmentation with Nonlinear Shape Priors [PDF]

Lecture Notes in Computer Science, 2011
The Active Shape Model (ASM) is a segmentation algorithm which uses a Statistical Shape Model (SSM) to constrain segmentations to 'plausible' shapes. This makes it possible to robustly segment organs with low contrast to adjacent structures. The standard SSM assumes that shapes are Gaussian distributed, which implies that unseen shapes can be expressed

Enhancing Facial Feature Detection: Hybrid Active Shape and Active Appearance Model (HASAAM)

IEEE Access
Face landmarking is a primary goal of many projects that lead to face-preparing activities, like biometric recognition and mental state comprehension. Despite the inherent diversity of faces, the topic has proven to be extremely difficult due to a wide ...

Autonomous Prostate Segmentation in 2D B-Mode Ultrasound Images

Applied Sciences, 2022
Prostate brachytherapy is a treatment for prostate cancer; during the planning of the procedure, ultrasound images of the prostate are taken. The prostate must be segmented out in each of the ultrasound images, and to assist with the procedure, an ...

Active Shape Models and the Shape Approximation Problem. [PDF]

Procedings of the British Machine Vision Conference 1995, 1995
Active Shape Models (ASM) use an iterative algorithm to match statistically defined models of known but variable objects to instances in images. Each iteration of ASM search involves two steps: image data interrogation and shape approximation. Here we consider the shape approximation step in detail.
