+# Image Focus Crop
+
+This module uses a few techniques, like face detection or entropy-based measure,
+to calculate the focal point of an image in order to provide a better "scale
+and crop" action.
+
+Unlike other similar modules, Image Focus works with any image toolkit (both GD
+and Image Magick) and does not require any extra user input.
+
+For a full description of the module, visit the
+[project page](https://drupal.org/project/image_focus).
+
+Submit bug reports and feature suggestions, or track changes in the
+[issue queue](https://www.drupal.org/project/issues/image_focus).

+## Requirements

+
+
+## Installation
+
+Install as you would normally install a contributed Drupal module. For further
+information, see
+[Installing Drupal Modules](https://www.drupal.org/docs/extending-drupal/installing-drupal-modules).
+
+
+## Configuration
+
+1. Use the image_focus_scale_and_crop action
+2. Modify Face detection threshold
+
+The PHP implementation is known to be very slow. Images larger than 50 KB will
+be ignored. To modify this threshold, please override the variable
+'image_focus_face_detection_maxsize'.
