Lung Segmentation using Distance Regularized Level Set Evolution (DRLSE)

This MATLAB code implements the Distance Regularized Level Set Evolution (DRLSE) method for segmenting lung MRI images. DRLSE is a technique used for contour extraction and object segmentation, designed to avoid the need for re-initialization by maintaining the regularity of the level set function during evolution.

Overview The method works by evolving a contour (represented by a level set function, phi) to capture the boundaries of the lungs.

Unlike traditional Level Set Evolution (LSE), this approach adds a distance regularization term to the energy function, ensuring stable evolution and eliminating the need for re-initialization.

Main Features DRLSE Algorithm: Uses a regularized distance term to maintain contour smoothness and stability. Energy Function Components: Regularization term 𝑅 𝑝 ( 𝜙 ) R p ​ (ϕ) (weighted by mu) Length term 𝐿 𝑔 ( 𝜙 ) biography matlab code for lung segmentation3 FEFYS
