textureFeatures on 2D jpg/png

Hi,

I was looking on the textureFeatures from the Medical Imaging Toolbox and it seem it can calculate different texture features (GLCM, GLRLM, etc) but what I can not find is can it be used on a single 2D jpg/png image and not on a medicalVolume. Does someone as an idea if it is possible and how?

What I know is possible is using graycomatrix/graycoprops using the code below.

clc;
clear all;
jpgI = imread('https://www.mathworks.com/help/examples/medical/win64/ComputeTextureFeaturesForComputedTomographyCTImageExample_01.png');
glcm = graycomatrix(jpgI)
jpgStats = graycoprops(glcm)

Thanks a lot in advance.

Hello @John Sal,

I understand that you are interested in finding texture features for a single 2D image.

You can refer to the below link for computing “Gray Level Run Length Matrix”.

https://www.mathworks.com/matlabcentral/fileexchange/17482-gray-level-run-length-matrix-toolbox

We can also extract texture features using “Local Binary Patterns” as shown below,

lbpFeatures = extractLBPFeatures(jpgI)

For more information on “LBP” feature extraction, please refer the below link.

Hope you find this information helpful.

Hi,

Thanks for the reply and the helpful information. I will look at them.

The main advantage of textureFeatures is that it can do GLCM, GLRLM, GLSZM, GLDZM, NGTDM and NGLDM in one run. This is why I find it unique and extremely good.
