| - | ===== Face shape annotations for the RWTH-PHOENIX corpus ===== | ||
| - | You can download [[https://iis.uibk.ac.at/public/RWTH-PHOENIX-face-shape-annotations.tar.gz|here]] our face shape annotations -- along with the corresponding images -- for the seven signers who appear in the RWTH-PHOENIX corpus. | ||
| - | The archive contains one directory by signer, each of which contains an "images" subdirectory and a "points" subdirectory. All image files are 300X260 PNG images. | ||
| - | All face shape annotation files are ASCII files with the filename extension ".pts". | ||
| - | |||
| - | === Distribution of the annotated images among the signers === | ||
| - | In total 369 images from the RWTH-PHOENIX corpus (more precisely from the RWTH-PHOENIX-v02-split01-TRAIN snapshot) have been manually annotated with the face shape. | ||
| - | |||
| - | ^ Signer ^ # annotated images ^ | ||

| - | | Karina Orlowski | 42 | | ||

| - | === Structure of a face shape annotation file (".pts" file) === | ||
| - | |||
| - | 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 axis 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: | ||
| - | |||
| - | version: 1 | ||
| - | n_points: 38 | ||
| - | { | ||
| - | x_1 y_1 | ||
| - | x_2 y_2 | ||
| - | ... | ||
| - | x_38 y_38 | ||
| - | } | ||
| - | |||
| - | {{:playground:phoenix-annotated-face.jpg?nolink& |Face shape annotation example}} | ||
| - | |||
| - | A possible interpretation of the shape points as face parts is as follows (using zero-based indexing in the list of points of a ".pts" file): | ||
| - | |||
| - | ^ Shape point indices ^ Face part ^ | ||
| - | |0-1-2 | upper part of the left eyebrow| | ||
| - | |3-4-5 | upper part of the right eyebrow| | ||
| - | |6-7-8-9 | eyelids of the left eye| | ||
| - | |10-11-12-13 | eyelids of the right eye| | ||
| - | |14-15 | nasal ridge| | ||
| - | |16-17 | nasal base| | ||
| - | |18-19-20-21-25-24 | upper lip| | ||
| - | |18-23-22-21-26-27 | lower lip| | ||
| - | |28-29-30-31-32-33-34-35-36-37 | cheeks and chin| | ||
| - | <html><br></html> | ||
| - | N.B. The original images from the RWTH-PHOENIX corpus do not have square pixels and come in 210X260 image resolution. | ||
| - | Therefore the annotated data provided here should be scaled appropriately if the goal is to build models that are relevant to | ||
| - | the entire corpus from these data. Scaling both the images and the shapes by a factor 210/300 | ||
| - | //in the horizontal direction only// (x-coordinates) will do the trick! | ||
