+# imagesToDataset
+Gets all the images from the directories 'object' and 'noobject', and puts in a dataset file.
+The dataset file is a dataset.data file that contains 2 columns:
+- images arrays of pixels
+- 0 or 1, depending if is from the 'noobject' or 'object' directory
+
+
+First, install the libraries.
