In this paper we incorporate an active contours energy into the Marked Point Process (MPP) framework. The addition of this energy allows the MPP model to detect objects with irregular shapes. This energy accounts for the elasticity and curvature properties of the detected objects. We employ the balloon method to prevent the contour from stagnating at local minima. We use calculus of variations to evolve each individual contour and we use stochastic multiple birth and death dynamics to optimize the MPP energy function. We demonstrate that our method successfully models components with irregular shape in material images, but the model can be extended to other applications.

More about this publication?
  • For more than 30 years, the Electronic Imaging Symposium has been serving those in the broad community - from academia and industry - who work on imaging science and digital technologies. The breadth of the Symposium covers the entire imaging science ecosystem, from capture (sensors, camera) through image processing (image quality, color and appearance) to how we and our surrogate machines see and interpret images. Applications covered include augmented reality, autonomous vehicles, machine vision, data analysis, digital and mobile photography, security, virtual reality, and human vision. IS&T began sole sponsorship of the meeting in 2016. All papers presented at EIs 20+ conferences are open access.

    Please note: For purposes of its Digital Library content, IS&T defines Open Access as papers that will be downloadable in their entirety for free in perpetuity. Copyright restrictions on papers vary; see individual paper for details.
