Information is abundantly available in various forms in the digital age, including text and images. While text is easily accessible and understood by computers, extracting valuable information from images has traditionally been challenging. However, advancements in artificial intelligence have revolutionized this process. One such breakthrough is the ability of ChatGPT, a state-of-the-art language model developed by OpenAI, to extract text from images. But how does ChatGPT extract text from images?

How ChatGPT Extracts Text From Images

ChatGPT extracts text from images with the help of OpenAI’s Code Interpreter. It is a Python-based ChatGPT plugin that enhances the generative AI tool’s abilities. Thanks to the GPT-4 VLM (visual language model), ChatGPT converts images to text with the aid of computer vision. A specific kind of computer vision is used, called optical character recognition technology (OCR technology). This deep learning tech recognizes a subject, like alphabetical letters or human faces, present in an image. It then converts this visual data (pixels) into a machine-readable format.

Using a GPT (Generative Pre-trained Transformer) like ChatGPT’s GPT-4 for data extraction via image recognition is in an advanced computer process only possible with artificial intelligence. OCR software uses computer vision models to interface between what a human would subjectively say they can see, and what a computer can objectively process in some usable way.

This process presents a different content creation use for the chatbot other than the standard text input prompts. It proves the growing uses of complex large language model (LLM) algorithms and convolutional neural networks (CNNs).

Here’s how the image-to-text extraction works:

  • Image Processing: The first step is to preprocess the image and prepare it for analysis. This may involve resizing, enhancing contrast, and noise reduction.
  • Text Detection: ChatGPT employs advanced object detection techniques to identify regions in the image that likely contain text. This involves identifying shapes and patterns that resemble letters and words.
  • Feature Extraction: Once potential text regions are detected, ChatGPT extracts relevant features from these regions, such as font styles, sizes, and orientations. This information helps in reconstructing the text accurately.
  • Contextual Analysis: The extracted features are fed into the language model, where ChatGPT uses its contextual understanding of language to decipher the text. This step ensures that the extracted text makes sense within the context of the visual image.
  • Post-Processing: After text extraction from the image input, a post-processing step may be applied to refine the output, correct errors, and improve overall accuracy.
