How to use BLIP2

BLIP2 is a powerful tool that provides textual descriptions of the contents of an image. This guide will walk you through the process of using BLIP2 for image captioning in Takomo.

Step 1: What is BLIP2

BLIP2 is designed to provide a textual description of an image's content. It's a tool that can analyze an image and generate a description based on what it sees.

Step 2: Use the Image Captioning Template

In Takomo, there's an image captioning template available. For a quick start, you can use this template instead of building one from scratch. The template includes an input section where you can input an image, a BLIP2 node that processes the image, and an output section labeled "description" where the description of the image will be sent.

Step 3: Input an Image

Add an image to the input section. By default, BLIP2 will generate a description of whatever is in the image without any specific prompts.

Step 4: Run the Pipeline

After adding an image, run the pipeline to see the generated description. The description can be broad, such as "a large anteater walking through a forest."

Step 5: Ask Specific Questions

To get more specific information, you can ask BLIP2 specific questions about the image. For example, you can ask, "how many animals are in this picture?" Add this question to the prompt and run the pipeline again. BLIP2 should return a number indicating the number of animals in the picture.

Step 6: Use Multiple BLIP Nodes for Multiple Questions

If you want to ask multiple questions about an image, it's best to use multiple BLIP nodes. While you can ask several questions inside of one node, this can sometimes lead to issues. Therefore, it's best practice to use a separate BLIP node for each question.

To do this, add a secondary BLIP node and connect the same image input to this node. You can then ask another question, such as "what is this animal?" and add another output field for the answer.

Step 7: Run the Pipeline Again

After setting up the additional BLIP node and output field, run the pipeline again. You should now get answers to all your questions about the image.

Remember, if you encounter any errors when using a BLIP2 node, ensure that you have all the questions in different BLIP2 nodes. This practice will help you avoid potential issues and get the most out of BLIP2.
