Image Captioning with PyTorch: A Practical Introduction Introduction

If you’ve worked with computer vision, you know classification is just the beginning. With PyTorch, you can go beyond that and build systems that actually describe images.

Here’s a helpful reference to get started:

Image captioning is the process of generating textual descriptions for images using deep learning.

𝗖𝗼𝗿𝗲 𝗖𝗼𝗺𝗽𝗼𝗻𝗲𝗻𝘁𝘀

  1. CNN (Encoder)
    Extracts features from the image

  2. RNN / Transformer (Decoder)
    Generates captions

  3. Dataset
    Common datasets include MSCOCO

𝗕𝗮𝘀𝗶𝗰 𝗪𝗼𝗿𝗸𝗳𝗹𝗼𝘄
1.Load and preprocess images
2.Extract features using CNN
3.Train a sequence model
4.Generate captions
5.Real-World Use Case

In one of our implementations at Oodles, we built a PyTorch-based image captioning system to automate content tagging and improve searchability.

  • PyTorch is flexible and powerful
  • Image captioning combines CV + NLP
  • Real value comes from automation
