視覚化ツール
適切に検出されたボックス、キーポイント、セグメンテーションで画像を視覚化するには、TensorFlow Object Detection API を使用します。リポジトリをクローンしてインストールします。
# Clone the tensorflow models repositorygit clone --depth 1 https://github.com/tensorflow/models
Cloning into 'models'... remote: Enumerating objects: 4065, done. remote: Counting objects: 100% (4065/4065), done. remote: Compressing objects: 100% (3109/3109), done. remote: Total 4065 (delta 1183), reused 1933 (delta 896), pack-reused 0 Receiving objects: 100% (4065/4065), 56.43 MiB | 40.33 MiB/s, done. Resolving deltas: 100% (1183/1183), done.
オブジェクト検出 API をインストールします。
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
これで、後で必要になる依存関係をインポートすることができます。

from object_detection.utils import visualization_utils as viz_utils
from object_detection.utils import ops as utils_ops
%matplotlib inline
ラベルマップデータを読み込む（プロット用）
ラベルマップはインデックス番号とカテゴリ名に対応しているため、畳み込みネットワークが5を予測した場合、これは airplane に対応していることが分かります。ここでは内部のユーティリティ関数を使用していますが、適切な文字列ラベルに整数をマッピングしたディクショナリを返すものであれば何でも構いません。
ここでは簡単にするため、オブジェクト検出 API コードを読み込んだリポジトリから読み込みます。
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)
検出モデルを構築し、事前トレーニング済みモデルの重みを読み込む
ここで、使用するオブジェクト検出モデルを選択します。アーキテクチャを選択すると、自動的に読み込みます。後でモデルを変更して他のアーキテクチャを試す場合には、次のセルを変更してその次のセルで実行してください。
ヒント: 選択したモデルの詳細については、リンク（モデルのハンドル）を辿り、TF Hub の追加ドキュメントを読むことができます。特定のモデルを選択した後で、ハンドルを出力すると簡単です。

画像を読み込む
簡単な画像を使ってこのモデルを試してみましょう。これを支援するために、テスト画像のリストを用意しています。
興味がある方は、次のような単純なことを試してみてください。
- 独自の画像で推論を実行してみましょう。Colab にアップロードして以下のセルと同じ方法で読み込むだけです。
- いくつかの入力画像を変更して、検出がまだ機能するかどうかを確認してみましょう。ここで簡単に試せるのは、画像を水平方向に反転させたり、グレースケールに変換（入力画像には 3 つのチャンネルがあることに注意してください）したりすることです。
注意: アルファチャンネルを持つ画像を使用する場合、モデルは 3 チャンネルの画像を想定しているため、アルファは 4 番目としてカウントされます。
Image Selection (don't forget to execute the cell!)
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])
plt.show()
推論を行う
推論を行うには、TF Hub を搭載したモデルを呼び出す必要があります。
以下を試すことができます。
result['detection_boxes']をプリントアウトして、ボックスの位置を画像内のボックスに一致させます。座標は正規化された形で（すなわち、間隔 [0, 1] で）与えらることに注意してください。- 結果に含まれる他の出力キーを確認します。完全なドキュメントは、モデルのドキュメントページで見ることができます（ブラウザで上記でプリントアウトしたモデルハンドルをポイントします）。
# 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())

結果を可視化する
ここで TensorFlow オブジェクト検出 API を使用して、推論ステップの四角形（および可能な場合はキーポイント）を表示します。
このメソッドの完全なドキュメントはこちらを参照してください。
ここでは、たとえば min_score_thresh をほかの値（0 と 1 の間）に設定して、より多くの検出を許可したり、より多くの検出をフィルターで除外したりすることができます。
label_id_offset = 0
image_np_with_detections = image_np.copy()
# Use keypoints if available in detections
keypoints, keypoint_scores = None, None
if 'detection_keypoints' in result:
keypoints = result['detection_keypoints'][0]
keypoint_scores = result['detection_keypoint_scores'][0]
viz_utils.visualize_boxes_and_labels_on_image_array(
image_np_with_detections[0],

［オプション］
利用可能なオブジェクト検出モデルに Mask R-CNN というモデルがありますが、このモデルの出力ではインスタンスセグメンテーションが可能です。
これを可視化するためには、上記と同じメソッドを使用しますが、次の追加のパラメータを追加します。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,
tf.uint8)
result['detection_masks_reframed'] = detection_masks_reframed.numpy()
viz_utils.visualize_boxes_and_labels_on_image_array(
