Hi Bernado
I need to compare two fingerprint images and let me know if you can do with
R. I have used the technique of minutiae but it seems to work better with the
cross-correlation and wanted to know if you can do with R.
First run this code:
for (i in 1:1000) cat("
Please follow the Posting Guide.
")
And if that didn't help run
help.request()
giving forthright answers to the questions.
Then return with commented, minimal, self-contained, reproducible code (as
you were asked to do).
You might also include some discussion of why the functions and packages
revealed by the 'Do Your Homework' section of the Posting Guide fall short
of your needs. Better still illustrate such problems with the code you
submit here.
HTH,
Chuck
Thank you very much

Hi juan,
You was a quite vage in your question, so I don't know exactly what you
need but try this;
require(ReadImages)
x <- read.jpeg(image1)
x1 <- read.jpeg(image2)
table(x1==x)
