How can Tensorflow and pre-trained model be used to convert images from one dimension to another?

Tensorflow Server Side Programming Programming

Tensorflow and the pre-trained model can be used to convert images from one dimension to another by iterating through the image dataset and using the previously created ‘base_model’ to convert it to the required dimension.

A neural network that contains at least one layer is known as a convolutional layer. We can use the Convolutional Neural Network to build learning model.

We will understand how to classify images of cats and dogs with the help of transfer learning from a pre-trained network. The intuition behind transfer learning for image classification is, if a model is trained on a large and general dataset, this model can be used to effectively serve as a generic model for the visual world. It would have learned the feature maps, which means the user won’t have to start from scratch by training a large model on a large dataset.

We are using the Google Colaboratory to run the below code. Google Colab or Colaboratory helps run Python code over the browser and requires zero configuration and free access to GPUs (Graphical Processing Units). Colaboratory has been built on top of Jupyter Notebook.

Example

print("Converting images from one dimension to another")
image_batch, label_batch = next(iter(train_dataset))
feature_batch = base_model(image_batch)
print(feature_batch.shape)

Output

Converting images from one dimension to another
(32, 5, 5, 1280)

Explanation

The feature extractor converts images that are 160x160x3 into a 5x5x1280 block of features.
The final dimensions are displayed on the console.
