Toolset for Vision Agent

🔍🤖 Vision Agent

Vision Agent is a library that helps you utilize agent frameworks for your vision tasks. Many current vision problems can easily take hours or days to solve, you need to find the right model, figure out how to use it, possibly write programming logic around it to accomplish the task you want or even more expensive, train your own model. Vision Agent aims to provide an in-seconds experience by allowing users to describe their problem in text and utilizing agent frameworks to solve the task for them.

Getting Started

Installation

To get started, you can install the library using pip:

pip install vision-agent

Ensure you have an OpenAI API key and set it as an environment variable (if you are using Azure OpenAI please see the additional setup section):

export OPENAI_API_KEY="your-api-key"

Vision Agents

You can interact with the agents as you would with any LLM or LMM model:

>>> from vision_agent.agent import VisionAgent
>>> agent = VisionAgent()
>>> agent("What percentage of the area of this jar is filled with coffee beans?", image="jar.jpg")
"The percentage of area of the jar filled with coffee beans is 25%."

To better understand how the model came up with it's answer, you can also run it in debug mode by passing in the verbose argument:

>>> agent = VisionAgent(verbose=True)

You can also have it return the workflow it used to complete the task along with all the individual steps and tools to get the answer:

>>> resp, workflow = agent.chat_with_workflow([{"role": "user", "content": "What percentage of the area of this jar is filled with coffee beans?"}], image="jar.jpg")
>>> print(workflow)
[{"task": "Segment the jar using 'grounding_sam_'.",
  "tool": "grounding_sam_",
  "parameters": {"prompt": "jar", "image": "jar.jpg"},
  "call_results": [[
    {
      "labels": ["jar"],
      "scores": [0.99],
      "bboxes": [
        [0.58, 0.2, 0.72, 0.45],
      ],
      "masks": "mask.png"
    }
  ]],
  "answer": "The jar is located at [0.58, 0.2, 0.72, 0.45].",
},
{"visualize_output": "final_output.png"}]

Tools

There are a variety of tools for the model or the user to use. Some are executed locally while others are hosted for you. You can also ask an LLM directly to build a tool for you. For example:

>>> import vision_agent as va
>>> llm = va.llm.OpenAILLM()
>>> detector = llm.generate_detector("Can you build a jar detector for me?")
>>> detector("jar.jpg")
[{"labels": ["jar",],
  "scores": [0.99],
  "bboxes": [
    [0.58, 0.2, 0.72, 0.45],
  ]
}]

Tool	Description
CLIP	CLIP is a tool that can classify or tag any image given a set of input classes or tags.
GroundingDINO	GroundingDINO is a tool that can detect arbitrary objects with inputs such as category names or referring expressions.
GroundingSAM	GroundingSAM is a tool that can detect and segment arbitrary objects with inputs such as category names or referring expressions.
Counter	Counter detects and counts the number of objects in an image given an input such as a category name or referring expression.
Crop	Crop crops an image given a bounding box and returns a file name of the cropped image.
BboxArea	BboxArea returns the area of the bounding box in pixels normalized to 2 decimal places.
SegArea	SegArea returns the area of the segmentation mask in pixels normalized to 2 decimal places.
BboxIoU	BboxIoU returns the intersection over union of two bounding boxes normalized to 2 decimal places.
SegIoU	SegIoU returns the intersection over union of two segmentation masks normalized to 2 decimal places.
ExtractFrames	ExtractFrames extracts frames with motion from a video.

It also has a basic set of calculate tools such as add, subtract, multiply and divide.

Additional Setup

If you want to use Azure OpenAI models, you can set the environment variable:

export AZURE_OPENAI_API_KEY="your-api-key"
export AZURE_OPENAI_ENDPOINT="your-endpoint"

You can then run Vision Agent using the Azure OpenAI models:

>>> import vision_agent as va
>>> agent = va.agent.VisionAgent(
>>>     task_model=va.llm.AzureOpenAILLM(),
>>>     answer_model=va.lmm.AzureOpenAILMM(),
>>>     reflection_model=va.lmm.AzureOpenAILMM(),
>>> )
