Export features extraction as a .mat file

After I extract the features of an image, I want it to save as .mat file but I don't know how? Please help me!

[deepika musuluri]

Could any please tell me what are the features those can be extracted for an image for the purpose of signature detection using MATLAB please tell me the procedure too

save('NameOfMatFile.mat', 'MEAN', 'SD', 'ENTROPY', 'RMS' and so on)

This assumes that you have stored the value you labelled MEAN in a variable named MEAN .

If you have a bunch of uicontrol edit boxes then it is possible to extract their String properties and save those, but since you are extracting features from an image you have already calculated those into variables and you might as well save the numeric variables directly.

This helps me but I want it to save as one file not as individual. Like, the mean,sd,entropy ... will save in one mat file. ( Like the image below but in .mat file )

[Image Analyst]

The way Walter showed you will save it as one mat file. All the variables you list will be in that same mat file. Try it and see. Use load() to read them back out of the mat file.

I load it and this is the result.

But I want to happen is like this.

hi thank you for your answer

Loop over the blobs or images, for each construct a row vector of the properties you want in the order you want. Use each of those row vectors as a row in a matrix. At the end, save the matrix.
