02 Generate image variations of an input image | @OpenAI DALL-E API

Hey everyone, welcome back to my YouTube channel. I am Sunny, your host. In today's video, we will be continuing our OpenAI DALL-E API playlist. In our last video, we set up our project and demonstrated how to generate images from textual descriptions using the DALL-E API.

Now, in this video, we are going to take it one step further and show you how to create image variations by passing an input image to the API instead of a text prompt. You will see that with just a few lines of code and an input image, you can generate a variety of new images that are sure to inspire your creativity. So, whether you are a developer looking to incorporate the latest AI technology into your projects or an enthusiast interested in exploring the cutting edge of image generation, this video is for you.

1. Introduction

We will learn how to create stunning image variations using the OpenAI DALL-E API. This demonstration will help you understand the process and implement it in your own projects.

2. Setting Up the Notebook

First, select the kernel for the notebook and run the initial setup code. Here are the basic imports and references for you.

import openai
import PIL
from io import BytesIO
import numpy as np
import matplotlib.pyplot as plt

## Introduction

3. Loading the Input Image

For this demonstration, let's choose an input image generated by DALL-E itself. Copy the relative path of the image to use it in the code.

input_image_path = "../input_images/example_image.png"

## Introduction
input_image = open(input_image_path, 'rb').read()
img = PIL.Image.open(BytesIO(input_image))
plt.imshow(img)
plt.axis('off')
plt.show()

4. Generating Image Variations

We will generate variations of the input image by passing it to the DALL-E API. Set the number of variations (n) and the size of the images.

## Introduction
n = 3
size = "512x512" 

## Introduction
response = openai.Image.create_variation(
    image=input_image,
    n=n,
    size=size
)

5. Displaying and Saving the Variations

After generating the variations, display and save them.

## Introduction
for i, img_data in enumerate(response['data']):
    img = PIL.Image.open(BytesIO(img_data['image']))
    plt.imshow(img)
    plt.axis('off')
    plt.show()
    img.save(f"output_images/variation_(i).png")

6. Conclusion

In this demonstration, we explored how to create image variations using the OpenAI DALL-E API. In the next video, we will look into image edits where you can pass a mask along with the prompt. Until then, keep exploring and learning. Thank you.

FAQ

Q1: What is the purpose of this tutorial? A1: The purpose of this tutorial is to demonstrate how to create image variations using the OpenAI DALL-E API by passing an input image instead of a text prompt.

Q2: What are the prerequisites for this tutorial? A2: You need to have a basic understanding of Python, the OpenAI DALL-E API, and some experience with image processing.

Q3: Can I use any image as an input image? A3: Yes, you can use any image as an input image to generate variations. However, the results may vary depending on the content of the image.

Q4: How many variations can I generate at once? A4: You can specify the number of variations (n) you want to generate. The API allows you to adjust this parameter based on your needs.

Q5: What are the available image sizes for variations? A5: The available image sizes for variations are: 512x512, 1024x1024, and 256x256 pixels.

Q6: How can I save the generated variations? A6: You can save the generated variations using the PIL library in Python, as demonstrated in the tutorial. Simply call the save method on each variation image.
