VIDEO | How to implement Image Similarity Search with Python

What is Image Similarity Search API?

Image Similarity Search API is a powerful tool that allows developers to compare images based on their visual content and retrieve similar images from a database or the web. This technology leverages advanced algorithms to analyze the visual features of images, such as colors, textures, and shapes, and identify similarities between them.

‍

How Does it Work?

The Image Similarity Search API works by extracting key features from an input image and comparing them with features from other images in a dataset. It employs techniques like deep learning and computer vision to understand the content of images and measure their similarity.

When a query image is provided to the API, it processes the image and generates a feature vector representing its visual characteristics. Then, it searches through a collection of images to find those with similar feature vectors. The similarity between images is typically measured using distance metrics like Euclidean distance or cosine similarity.

Diverse Applications of Image Similarity Search

• E-commerce Optimization: Online retailers utilize image similarity search to offer personalized product recommendations based on visual similarities, enhancing user experience and driving sales.
• Efficient Content Management: Media companies and digital asset platforms employ image similarity search to organize and retrieve images efficiently, streamlining workflow and content categorization processes.
• Creative Inspiration in Art and Design: Artists and designers leverage image similarity search to discover visually similar images, artwork, or designs for inspiration, facilitating creative ideation and exploration.
• Security and Surveillance: Security agencies utilize image similarity search for suspect identification, object tracking, and pattern analysis across surveillance footage, enhancing crime prevention and investigation capabilities.

How to use Image Similarity Search on Eden AI

Step 1: Create an Account on Eden AI

To get started with the Eden AI API, you need to sign up for an account on the Eden AI platform. Once registered, you will get an API key that grants you access to the diverse set of image Similarity  providers available on the platform.

‍

Step 2: Choose Your Image Source

Before diving into the code, decide where your query image is located:

• File URL: If your image is hosted online, you'll use its URL.
• Local File: If your image is stored locally on your machine, you'll provide its file path.

Step 3: Get the Python Code Snippet

Now, let's get to the code. Depending on your image source choice, you'll use different code snippets.

‍

Using File URL

If you're using a file hosted online, here's the Python code snippet:

import json
import requests

headers = {"Authorization": "Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJ1c2VyX2lkIjoiOWRmYTBmMDEtOTZlNS00ZWVjLTlhMTEtODM4M2Y2YjM0ZTY2IiwidHlwZSI6ImFwaV90b2tlbiJ9.vxdZl0DF2xO9xOnpBwNNXv8XA3D5fOxTX-JEBNlNkqk"}

url = "https://api.edenai.run/v2/image/search/launch_similarity"
json_payload = {
    "providers": "sentisight",
    "file_url": "🔗 URL of your image"
}

response = requests.post(url, json=json_payload, headers=headers)

result = json.loads(response.text)
print(result["sentisight"])

‍

Ensure to replace "🔗 URL of your image" with the actual URL of your image. The image you specify here will be used as the query for the similarity search.

‍

Using Local File

If your image is stored locally, use the following code snippet:

import json
import requests

headers = {"Authorization": "Bearer your_bearer_token_here"}

url = "https://api.edenai.run/v2/image/search/launch_similarity"
data = {"providers": "sentisight"}
files = {'file': open("🖼️ path/to/your/image.png", 'rb')}

response = requests.post(url, data=data, files=files, headers=headers)
result = json.loads(response.text)
print(result['sentisight'])

Replace "🖼️ path/to/your/image.png" with the actual path to your image file. This image will serve as the query for the similarity search.

Additionally, you can change the value of "providers" in both codes to any supported provider on Eden AI you want to use for the image similarity search.

‍

By following these steps, you can harness the power of Eden AI's Image Similarity Search API to find visually similar images with ease. Whether you are working with images hosted online or stored locally, Eden AI provides a seamless and efficient way to integrate image similarity search into your projects. Experiment with different providers and customize the search to suit your specific needs, making the most out of this powerful tool.

Adding New Images to Your Dataset for Image Similarity Search

In the previous tutorial, we learned how to use the Eden AI Image Similarity Search API to find similar images using a URL or local file. Now, by learning how to add new images to your dataset, you can continually update and refine your image library, making your similarity searches even more effective. Whether you are adding images from an online source or uploading them directly from your device, these steps will help you manage your dataset with ease.

Step-by-Step Guide

Original Code from Eden AI Documentation

Before we dive into the specific cases, here is the original code from Eden AI documentation:

import requests

url = "https://api.edenai.run/v2/image/search/upload_image"

payload = {
    "response_as_dict": True,
    "attributes_as_list": False,
    "show_original_response": False
}
headers = {
    "accept": "application/json",
    "content-type": "application/json",
    "authorization": "Bearer your_bearer_token_here"
}

response = requests.post(url, json=payload, headers=headers)

print(response.text)

‍

Adding Images via URL

When adding images via URL, you send the image URL to the API endpoint, which then processes and adds the image to your dataset.

import requests

url = "https://api.edenai.run/v2/image/search/upload_image"

payload = {
    "response_as_dict": True,
    "attributes_as_list": False,
    "show_original_response": False,
    "providers": "sentisight,nyckel",
    "image_name": "test.jpg",
    "file_url": "http://edenai-resource-example.jpg"
}
headers = {
    "accept": "application/json",
    "content-type": "application/json"
}

response = requests.post(url, json=payload, headers=headers)

print(response.text)

‍

Modified Code Example

Here is how you can modify the code to add an image via URL:

1. Payload Modifications: Add "providers", "image_name", and "file_url" to the payload.
   1. Specify the providers you want to use.
   2. Provide the name of the image (optional).
   3. Specify the URL of the image you want to add to your dataset.
2. Header Modifications: Remove the "authorization"  header since it's not required for URL uploads.
3. Request Modifications: Use the “requests.post” method with payload and headers to send the request to the API endpoint.

‍

Adding Images via Local File

When adding images from a local file, you need to send the file data directly to the API.

import requests

url = "https://api.edenai.run/v2/image/search/upload_image"

payload = {
    "response_as_dict": True,
    "attributes_as_list": False,
    "show_original_response": False,
    "providers": "sentisight",
    "image_name": "car5.jpeg"
}
headers = {
   "authorization": "Bearer dummy_token_for_demo_purposes"
}
files = {'file': open("./Assets/car3.jpeg", "rb")}

response = requests.post(url, data=payload, files=files, headers=headers)

print(response.text)

‍

Modified Code Example

Here is how you can modify the code to add an image via local file:

1. Payload Modifications: Add "providers" and "image_name" to the payload.
   1. Specify the providers you want to use.
   2. Provide the name of the image.
2. Header Modifications:
   1. Ensure that the "authorization" header remains unchanged as it's still required for file uploads.
   2. Remove "accept" and "content-type" since it is not required for local file uploads.
3. Specify the path to the local file you want to upload.
4. Request Modifications: Use the "requests.post" method with both payload, files, and headers to send the request to the API endpoint.
