IllusionVQA: Optical Illusion Dataset

Project Page | Paper | Github

TL;DR

IllusionVQA is a dataset of optical illusions and hard-to-interpret scenes designed to test the capability of Vision Language Models in comprehension and soft localization tasks. GPT4V achieved 62.99% accuracy on comprehension and 49.7% on localization, while humans achieved 91.03% and 100% respectively.

Usage

from datasets import load_dataset
import base64
from openai import OpenAI
import os
os.environ["OPENAI_API_KEY"] = "YOUR_API_KEY"

def encode_image(pil_image):
    temp_name = "temp.jpg"
    pil_image.save(temp_name)
    with open(temp_name, "rb") as image_file:
        return base64.b64encode(image_file.read()).decode("utf-8")

def construct_mcq(options, correct_option):
    correct_option_letter = None
    i = "a"
    mcq = ""
    for option in options:
        if option == correct_option:
            correct_option_letter = i
        mcq += f"{i}. {option}\n"
        i = chr(ord(i) + 1)
    mcq = mcq[:-1]
    return mcq, correct_option_letter

def add_row(content, data, i, with_answer=False):  
    mcq, correct_option_letter = construct_mcq(data["options"], data["answer"])
    content.append({ "type": "text",
            "text": "Image " + str(i) + ": " + data["question"] + "\n" + mcq })
    content.append({ "type": "image_url",
            "image_url": {"url": f"data:image/jpeg;base64,{encode_image(data['image'])}",
                "detail": "low"}})
    if with_answer:
        content.append({"type": "text", "text": "Answer {}: ".format(i) + correct_option_letter})
    else:
        content.append({"type": "text", "text": "Answer {}: ".format(i), })
    return content

dataset = load_dataset("csebuetnlp/illusionVQA-Comprehension")
client = OpenAI(api_key=os.getenv("OPENAI_API_KEY"))

content = [{
        "type": "text",
        "text": "You'll be given an image, an instruction and some choices. You have to select the correct one. Do not explain your reasoning. Answer with the option's letter from the given choices directly. Here are a few examples:",
    }]

### Add a few examples
for i, data in enumerate(dataset["train"], 1):
    content = add_row(content, data, i, with_answer=True)

content.append({"type": "text", "text": "Now you try it!",})

next_idx = i + 1

### Add the test data
test_data = dataset["test"][0]
content_t = add_row(content.copy(), test_data, next_idx, with_answer=False)

### Get the answer from GPT-4
response = client.chat.completions.create(
    model="gpt-4-vision-preview",
    messages=[{"role": "user","content": content_t,}],
    max_tokens=5,
)
gpt4_answer = response.choices[0].message.content
print(gpt4_answer)
