基於tensorflow + Vgg16進行影象分類識別

阿新 • • 發佈：2019-01-08

1. VGG-16介紹

vgg是在Very Deep Convolutional Networks for Large-Scale Image Recognition期刊上提出的。模型可以達到92.7%的測試準確度,在ImageNet的前5位。它的資料集包括1400萬張影象，1000個類別。
vgg-16是一種深度卷積神經網路模型，16表示其深度，在影象分類等任務中取得了不錯的效果。
vgg16 的巨集觀結構圖如下。程式碼定義在tensorflow的vgg16.py檔案。注意，包括一個預處理層，使用RGB影象在0-255範圍內的畫素值減去平均值（在整個ImageNet影象訓練集計算）。

2. 檔案組成

模型權重 - vgg16_weights.npz
TensorFlow模型- vgg16.py
類名（輸出模型到類名的對映） - imagenet_classes.py
示例圖片輸入 - laska.png
我們使用特定的工具轉換了原作者在GitHub profile上公開可用的Caffe權重，並做了一些後續處理，以確保模型符合TensorFlow標準。最終實現可用的權重檔案vgg16_weights.npz
下載所有的檔案到同一資料夾下，然後執行 python vgg16.py
