cnn_tools module

Functions to work with Keras CNNs used to classify IFCB phytoplankton images.

Imports:

• numpy
• cv2
• keras from tensorflow

Functions:

---

preprocess_input(image):

Takes in an IFCB .png (or list of IFCB .pngs) and resizes it to fit the input dimensions of the CNN.

Parameters:

• image (list): IFCB .png file or list of files.

Returns:

• rescaled_image (list): Rescaled IFCB image(s).

---

load_local_model(json_file_path, h5_file_path):

Loads locally saved model as Tensorflow keras model.

Parameters:

• json_file_path (str): Path to local .json model file.
• h5_file_path (str): Path to local .h5 model weights file.

Returns:

• loaded_model (tf.keras.Model): Loaded keras model.
