Measuring the length of a sample

One of the simplest parameter to measure in a segmented - binary - image is the length of your sample (a molecule, cellular or subcellular components, fibers, etc.).
I'll describe two techniques (manual and automatic) to get such information.

Graphics: Marching Squares - OOP Script

In this improved version of the Marching Squares algorithm - see description [Link] - I use an Object-Oriented Programming (OOP) approach...

Graphics: Marching Cubes - Results

From the script marchingCubes.js of the previous post [Link], here are some examples of isosurfaces rendered with Blender...

Graphics: Marching Cubes - Implementation

A javascript implementation of the Marching cubes algorithm...

Graphics: Marching Squares - No doubles

The previous implementation of the marching squares [Link] generates a lot of vertices because each segment line is defined by its own starting and ending points however all these line segments  are interconnected - forming a polyline - and this is not taken into account in the implementation. Here is a new version to reduce the number of vertices.

Graphics: Marching Squares

After describing the principle of the Marching Squares algorithm in a previous post [Link], it is time to implement it...
