Benvenuto nel TensorFlow Hub Object Detection Colab! Questo taccuino ti guiderà attraverso i passaggi per eseguire un modello di rilevamento degli oggetti "pronto all'uso" sulle immagini.
Più modelli
Questa raccolta contiene TF2 modelli di rilevamento di oggetti che sono stati addestrati sul COCO 2.017 set di dati. Qui si possono trovare tutti i modelli di rilevamento di oggetti che sono attualmente ospitati su tfhub.dev .
Importazioni e configurazione
Cominciamo con le importazioni di base.
# This Colab requires TF 2.5.pip install -U "tensorflow>=2.5"

Utilità
Esegui la cella seguente per creare alcuni programmi di utilità che saranno necessari in seguito:
- Metodo di supporto per caricare un'immagine
- Mappa del nome del modello sull'impugnatura dell'hub TF
- Elenco delle tuple con Human Keypoints per il set di dati COCO 2017. Questo è necessario per i modelli con punti chiave.

Strumenti di visualizzazione
Per visualizzare le immagini con i riquadri, i punti chiave e la segmentazione corretti rilevati, utilizzeremo l'API TensorFlow Object Detection. Per installarlo cloneremo il repository.
# Clone the tensorflow models repositorygit clone --depth 1 https://github.com/tensorflow/models

Installazione dell'API di rilevamento oggetti
sudo apt install -y protobuf-compilercd models/research/protoc object_detection/protos/*.proto --python_out=.cp object_detection/packages/tf2/setup.py .python -m pip install .
WARNING: apt does not have a stable CLI interface. Use with caution in scripts. dpkg-preconfigure: unable to re-open stdin: No such file or directory
Ora possiamo importare le dipendenze di cui avremo bisogno in seguito
from object_detection.utils import label_map_util

from object_detection.utils import ops as utils_ops
%matplotlib inline
Caricare i dati della mappa dell'etichetta (per la stampa).
Mappe Label corrispondono numeri indice di nomi di categoria, in modo che quando la nostra rete circonvoluzione prevede 5 , sappiamo che questo corrisponde ad airplane . Qui usiamo le funzioni di utilità interne, ma tutto ciò che restituisce un dizionario che mappa i numeri interi alle etichette di stringa appropriate andrebbe bene.
Stiamo andando, per semplicità, a caricare dal repository che abbiamo caricato il codice dell'API Object Detection
PATH_TO_LABELS = './models/research/object_detection/data/mscoco_label_map.pbtxt'
category_index = label_map_util.create_category_index_from_labelmap(PATH_TO_LABELS, use_display_name=True)
Crea un modello di rilevamento e carica i pesi del modello pre-addestrati
Qui sceglieremo quale modello di rilevamento oggetti utilizzeremo. Seleziona l'architettura e verrà caricata automaticamente. Se vuoi cambiare il modello per provare altre architetture in un secondo momento, cambia semplicemente la cella successiva ed esegui quelle seguenti.
Suggerimento: se si desidera leggere ulteriori dettagli circa il modello selezionato, è possibile seguire il link (maniglia modello) e leggere ulteriore documentazione sul TF Hub. Dopo aver selezionato un modello, stamperemo la maniglia per renderlo più semplice.

Caricamento di un'immagine
Proviamo il modello su una semplice immagine. Per aiutare con questo, forniamo un elenco di immagini di prova.
Ecco alcune semplici cose da provare se sei curioso:
- Prova a eseguire l'inferenza sulle tue immagini, caricale su colab e caricale allo stesso modo nella cella sottostante.
- Modifica alcune delle immagini di input e verifica se il rilevamento funziona ancora. Alcune semplici cose da provare qui includono il ribaltamento dell'immagine orizzontalmente o la conversione in scala di grigi (nota che ci aspettiamo ancora che l'immagine di input abbia 3 canali).
Attenzione: quando si usano le immagini con un canale alfa, il modello si aspettano 3 immagini canali e l'alfa conterà come un 4 °.
Selezione immagine (non dimenticare di eseguire la cella!)
selected_image = 'Beach' # @param ['Beach', 'Dogs', 'Naxos Taverna', 'Beatles', 'Phones', 'Birds']
flip_image_horizontally = False
convert_image_to_grayscale = False
image_path = IMAGES_FOR_TEST[selected_image]
image_np = load_image_into_numpy_array(image_path)
# Flip horizontally
if(flip_image_horizontally):
image_np[0] = np.fliplr(image_np[0]).copy()
# Convert image to grayscale
if(convert_image_to_grayscale):
image_np[0] = np.tile(
np.mean(image_np[0], 2, keepdims=True), (1, 1, 3)).astype(np.uint8)
plt.figure(figsize=(24,32))
plt.imshow(image_np[0])

Fare l'inferenza
Per fare l'inferenza abbiamo solo bisogno di chiamare il nostro modello caricato TF Hub.
Cose che puoi provare:
- Stampare
result['detection_boxes']e cercare di abbinare le sedi di dialogo per le caselle nell'immagine. Notare che le coordinate sono date in forma normalizzata (cioè, nell'intervallo [0, 1]). - ispezionare altre chiavi di output presenti nel risultato. Una documentazione completa può essere visualizzata nella pagina della documentazione dei modelli (puntando il browser all'handle del modello stampato in precedenza)
# running inference
results = hub_model(image_np)
# different object detection models have additional results
# all of them are explained in the documentation
result = {key:value.numpy() for key,value in results.items()}
print(result.keys())

Visualizzazione dei risultati
Qui è dove avremo bisogno dell'API TensorFlow Object Detection per mostrare i quadrati dalla fase di inferenza (e i punti chiave quando disponibili).
la documentazione completa di questo metodo può essere visto qui
Qui è possibile, per esempio, insieme min_score_thresh ad altri valori (tra 0 e 1) per consentire a più rilevamenti o per filtrare più rilevamenti.

[Opzionale]
Tra i modelli di rilevamento degli oggetti disponibili c'è Mask R-CNN e l'output di questo modello consente la segmentazione dell'istanza.
Per visualizzarlo useremo lo stesso metodo che abbiamo fatto prima, ma l'aggiunta di un parametro di adizionale: instance_masks=output_dict.get('detection_masks_reframed', None)
# Handle models with masks:
image_np_with_mask = image_np.copy()
if 'detection_masks' in result:
# we need to convert np.arrays to tensors
detection_masks = tf.convert_to_tensor(result['detection_masks'][0])
detection_boxes = tf.convert_to_tensor(result['detection_boxes'][0])
# Reframe the bbox mask to the image size.
detection_masks_reframed = utils_ops.reframe_box_masks_to_image_masks(
detection_masks, detection_boxes,
image_np.shape[1], image_np.shape[2])
detection_masks_reframed = tf.cast(detection_masks_reframed > 0.5,
