| * Importing the model | |
| ```python | |
| from devolearn import cell_membrane_segmentor | |
| segmentor = cell_membrane_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") | |
| ``` | |

| </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 | |

| * 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(device = "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, postprocess = False) | |
| ``` | |
| * 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, postprocess = False) | |
