Methods of Obtaining Topography

Topography involves measuring and mapping land elevations, natural features, and artificial structures to create accurate representations of the terrain. Topographic surveying relies on traditional and modern methods, each with distinct advantages and limitations.Traditional Surveying Methods:Transit stadia surveys and plane table surveys were widely used traditional surveying methods. These techniques relied on instruments like theodolites and stadia rods for measuring distances and angles,...

This study introduces a narrow band multiple level set method to improve remote sensing image segmentation. The new approach effectively segments homogeneous objects and eliminates redundant contours, enhancing accuracy.

Area of Science:

  • Computer Vision
  • Image Processing
  • Remote Sensing

Context:

  • Classical Chan-Vese (C-V) model struggles with remote sensing images due to interlaced edges, causing massive redundant contours.
  • The C-V model also fails to segment homogeneous objects composed of multiple distinct regions.

Purpose:

  • To overcome the limitations of the classical C-V model in segmenting complex remote sensing imagery.
  • To develop a novel segmentation method that addresses redundant contours and multi-region homogeneous objects.

Summary:

  • A narrow band multiple level set method is proposed, utilizing N-1 curves for N-region segmentation.
  • This method establishes independent multi-region representations, eliminating redundant contours and avoiding segmentation issues like vacuum and overlap.
