### Segmenting the C. elegans embryo 
<p align="center">
<img src = "https://raw.githubusercontent.com/DevoLearn/devolearn/master/images/pred_centroids.gif" width = "80%">
</p>

* Importing the model
```python
from devolearn import embryo_segmentor
segmentor = embryo_segmentor()

```

* Running the model on an image and viewing the prediction
```python
seg_pred = segmentor.predict(image_path = "sample_data/images/seg_sample.jpg")
plt.imshow(seg_pred)
plt.show()
```

* Running the model on a video and saving the predictions into a folder 
```python
filenames = segmentor.predict_from_video(video_path = "sample_data/videos/seg_sample.mov", centroid_mode = False, save_folder = "preds")
```

* Finding the centroids of the segmented features
```python
seg_pred, centroids = segmentor.predict(image_path = "sample_data/images/seg_sample.jpg", centroid_mode = True)
plt.imshow(seg_pred)
plt.show()
```

* Saving the centroids from each frame into a CSV

```python
df = segmentor.predict_from_video(video_path = "sample_data/videos/seg_sample.mov", centroid_mode = True, save_folder = "preds")
df.to_csv("centroids.csv")
```

### Generating synthetic images of embryos with a Pre-trained GAN

</p>

* Importing the model
```python
from devolearn import Generator, embryo_generator_model
generator = embryo_generator_model()

```

* Generating a picture and viewing it with [matplotlib](https://matplotlib.org/)
```python
gen_image = generator.generate()  
plt.imshow(gen_image)
plt.show()

```

* Generating n images and saving them into `foldername` with a custom size

```python
generator.generate_n_images(n = 5, foldername= "generated_images", image_size= (700,500))
```

</p>

* Importing the population model for inferences 
```python
from devolearn import lineage_population_model
```

* Loading a model instance to be used to estimate lineage populations of embryos from videos/photos.
```python
model = lineage_population_model(mode = "cpu")
```

* Making a prediction from an image
```python
print(model.predict(image_path = "sample_data/images/embryo_sample.png"))
```

* Making predictions from a video and saving the predictions into a CSV file
```python
results = model.predict_from_video(video_path = "sample_data/videos/embryo_timelapse.mov", save_csv = True, csv_name = "video_preds.csv", ignore_first_n_frames= 10, ignore_last_n_frames= 10 )
```

* Plotting the model's predictions from a video
```python
plot = model.create_population_plot_from_video(video_path = "sample_data/videos/embryo_timelapse.mov", save_plot= True, plot_name= "plot.png", ignore_last_n_frames= 0 )
plot.show()
```
