How to Use Radon Transform in Julia, MATLAB, Python

Julia¹

In the Tomography package Tomography.jl, one can use the radon() function.

• radon(f, θ): f stands for the image, θ for the projection angle. If not specified, it calculates from 0 degrees to $\pi$ by default.

using Tomography
using Plots

# 팬텀 생성
f = phantom(256,2)

# 라돈 변환 계산
ℛf = radon(f)

# 그림 출력
h1 = heatmap(reverse(f, dims=1), size=(400,400));
h2 = heatmap(reverse(ℛf, dims=1), size=(400,400));
heatmap(h1, h2, size=(800,400))

Environment

• OS: Windows10
