Hi,
The first step would be to import the txt file into MATLAB. You can do so in 2 ways.
  1. Use the Import Data optiom in the variable section on the home tab, and choose the output type as 'Numeric matrix'
  2. Use the below code snippet
A = readtable('metalpipe_er1_h5_d2.txt');
B = table2array(A);
In order to extract the HOG features, you can use the extractHOGFeatures function. The documentation is linked below:
There is no inbuilt function to extract EHD features, but you can refer to the Answer linked below, it describes extracting EHD features
