如何在Octave中使用MATLAB的regionprops函数的'solidity'属性? [英] How to use the 'solidity' property of the regionprops function of MATLAB in Octave?

问题描述

我在MATLAB中有一个代码，必须将其转换为Octave.我对以下命令有疑问:

I have a code in MATLAB that I have to convert into Octave. I have problems with the following command:

boxes = regionprops (L, 'Solidity')

其中 L 是二进制图像类double.

where L is a binary image class double.

八度不知道'Solidity'属性.是否可以使用类似的属性或函数在Octave中运行代码?

Octave does not know the 'Solidity' property . Is there a similar property or a function that I can use to run the code in Octave?

推荐答案

根据matlab

According to the definition of 'Solidity' in matlab regionprops this measurement is the Area/ConvexArea.

为了计算 ConvexArea ，请执行以下操作:

In order to calculate the ConvexArea do the following things:

1. 获取已连接组件像素的ID列表.使用: regioprops(I，'PixelIdxList')
2. 计算其 convexhull .使用: H = convhull(x，y)
3. 计算 convexhull 的面积.使用: polyarea(convexHullX，convexHullY)

1. Get id list of the connected component pixels. Use: regioprops(I,'PixelIdxList')
2. Calculate their convexhull. Use: H = convhull (x, y)
3. Calculate the area of the convexhull. Use: polyarea(convexHullX,convexHullY)
