Understanding Hand-Drawn Images with Image-to-Text Processing

Behind the scenes

Multimodal models such as Gemini can work with images as input. This enables them to analyze an image and generate a textual description of its content. Here’s a brief overview of how most image captioning models work:

• The image is first processed into a format that is easily digestible for the model.

• A CNN encoderA Convolutional Neural Network (CNN) encoder specializes in processing images/videos. It acts like a data summarizer, transforming raw visuals into a compact representation that captures the essence of the content. analyzes the image, extracting features like edges, objects, and their spatial relationships. This creates a compressed representation of the image’s visual content.

• The decoderDecoders are like translators. They take a condensed version of ...
