| - | For each image the face shape annotation consists of the ordered list of the positions of 38 facial landmarks. Each facial landmark | ||
| - | – or face shape point – has two coordinates in the coordinate system originating at the top-left corner of the image, with the x-axis pointing right | ||
| - | and the y-axis pointing down. The actual structure of a ”.pts” file is as follows: | ||

| - | Note: The original images from the RWTH-PHOENIX corpus do not have square pixels and come in 210×260 image resolution. | ||
| - | Therefore the annotated data provided here should be scaled appropriately if the goal is to use them to build models that are relevant to | ||
| - | the entire corpus. Scaling both our images and our shape annotations by a factor 210/300 | ||
| - | <em>in the horizontal direction only</em> (x-coordinates) will do the trick! | ||
