# Chart-based Dense Pose Estimation for Humans and Animals
## <a name="Overview"></a> Overview
The goal of chart-based DensePose methods is to establish dense correspondences
between image pixels and 3D object mesh by splitting the latter into charts and estimating
for each pixel the corresponding chart index `I` and local chart coordinates `(U, V)`.
<div align="center">
<img src="https://dl.fbaipublicfiles.com/densepose/web/densepose_teaser_compressed_25.gif" width="700px" />
</div>
The charts used for human DensePose estimation are shown in Figure 1.
The human body is split into 24 parts, each part is parametrized by `U` and `V`
coordinates, each taking values in `[0, 1]`.

</div>
<p class="image-caption"><b>Figure 1.</b> Partitioning and parametrization of human body surface.</p>
The pipeline uses [Faster R-CNN](https://arxiv.org/abs/1506.01497)
with [Feature Pyramid Network](https://arxiv.org/abs/1612.03144) meta architecture
outlined in Figure 2. For each detected object, the model predicts
its coarse segmentation `S` (2 or 15 channels: foreground / background or
background + 14 predefined body parts), fine segmentation `I` (25 channels:
background + 24 predefined body parts) and local chart coordinates `U` and `V`.

### <a name="Bootstrap"></a> Bootstrapping Chart-Based Models
[Sanakoyeu et al., 2020](https://arxiv.org/pdf/2003.00080.pdf) introduced a pipeline
to transfer DensePose models trained on humans to proximal animal classes (chimpanzees),
which is summarized in Figure 3. The training proceeds in two stages:
First, a *master* model is trained on data from source domain (humans with full
DensePose annotation `S`, `I`, `U` and `V`)
and supporting domain (animals with segmentation annotation only).
Only selected animal classes are chosen from the supporting
domain through *category filters* to guarantee the quality of target domain results.
The training is done in *class-agnostic manner*: all selected categories are mapped
to a single category (human).
Second, a *student* model is trained on data from source and supporting domains,
as well as data from target domain obtained by applying the master model, selecting
high-confidence detections and sampling the results.
<div align="center">
<img src="https://dl.fbaipublicfiles.com/densepose/web/densepose_pipeline_bootstrap_iuv.png" width="1000px" />
</div>
<p class="image-caption"><b>Figure 3.</b> Domain adaptation: <i>master</i> model is trained on data from source and
supporting domains to produce predictions in target domain; <i>student</i> model combines data from source and
supporting domains, as well as sampled predictions from the master model on target domain to improve
target domain predictions quality.</p>
Examples of pretrained master and student models are available in the [Model Zoo](#ModelZooBootstrap).

`Atop10P`: humans and animals from the 10 best suitable categories are used for training
`CA`: class agnostic training, where all annotated instances are mapped into a single category
`B_<...>`: schedule with bootstrapping with the specified results sampling strategy
Note:
The relaxed `dp. APex GPS` metric was used in
[Sanakoyeu et al., 2020](https://arxiv.org/pdf/2003.00080.pdf) to evaluate DensePose
results. This metric considers matches at thresholds 0.2, 0.3 and 0.4 additionally
to the standard ones used in the evaluation protocol. The minimum threshold is
controlled by `DENSEPOSE_EVALUATION.MIN_IOU_THRESHOLD` config option.
