Google processes 40,000 searches every second. When we consider the number of daily searches on Google, the number hovers around 1.2 million. Millions of people around the world use Google to search for information. With that being said, not everyone can find the right words to type on Google. Image-based searches are easier for users. Not to mention their accuracy. Searching for a product, such as a hair timer or body lotion, online can be hard. Additionally, the text on product packaging labels can be in other languages. For example, a pack of noodles may come with instructions in Mandarin or Cantonese.
This is where Google Lens comes into the picture. It can help people find what they want and know more about products. All they have to do is pull out their smartphones and point the camera at the particular image. Pointing the camera at the image helps Google Lens identify the object/product. Then it will proceed to provide further explanation to users. Google was developed to help understand text, but over time, it realized users needed help comprehending images too. Google understood this problem. Mr. Sundar Pichai unveiled Google Lens at Google’s developer conference in 2017.
Voice-powered searches have gained popularity in the past 5 to 6 years. With Google Lens, image-based searches become smooth and effortless. It provides users with an alternative way to search and understand information. What is Google Lens? How can people use it effectively? What are its real-world use cases? In this blog, we will cover multiple aspects related to Google Lens. This includes how to use it and its challenges. Let’s get into the details right away.
What is Google Lens?
Google Lens uses three innovative technologies. These technologies include:
- AI
- Machine Learning
- Image Recognition
Powered by these advanced technologies, Google Lens helps people search for information. They can also explore things and concepts. After analyzing the image, Google Lens provides users with accurate and up-to-date information. This information enables users to make the right decisions.
Users can get answers to questions such as the following:
- What is this product/thing?
- Where can I purchase it?
- If it's a foreign product, does it have local alternatives?
- Does the product have any cons/side effects?
- What does the text translate to in English?
How Does Google Lens Work?
Google Lens operates using deep neural networks. These neural networks are trained on a vast database comprising the following:
- Labelled Images
- Unlabeled Images
- Videos
- Multimodal Data Points
By accessing this vast database, the model learns how to distinguish between different products and objects. These objects can be different shapes and sizes. Google Lens can also distinguish products based on colors and textures. It can also read symbols, texts while understanding spatial relationships. Below is a detailed explanation of how Google Lens works.
1. Image Capturing and Preprocessing
After Google Lens scans an image, it does the following:
- Google Lens resizes, normalizes, and optimizes the image for a detailed analysis.
- Based on the image quality and requirements, Google Lens can also apply noise reduction, contrast adjustment, and edge detection.
- Additionally, Google Lens may analyse multiple frames in real-time. This is to enable live camera use.
Preprocessing the image ensures that it becomes clear and easy for AI to comprehend it before the analysis begins.
2. Visual Feature Extraction
Convolutional Neural Networks (CNNs) and Vision Transformers (ViTs) are what make Google Lens work. These are like the eyes and brain of Google Lens. What exactly do CNNs and ViTs do? They do the following:
- Breaks the image into different parts.
- Then Google Lens extracts basic details, including edges, curves, and colors.
- After grasping the basic details, artificial intelligence combines them to understand:
- Objects
- Faces and Symbols
- Popular Landmarks and Locations
After capturing details as mentioned above, Google Lens converts them into numbers. These numbers are also called embeddings. Embeddings are like the digital fingerprints of the image.
3. Object Detection
Using trained detection models accomplishes the following:
- Identifies the objects in a particular image. It also highlights the location.
- Then, Google Lens analyzes the surroundings and objects inside the image. In the next step, it identifies the location where the image was taken.
- Finally, it establishes the connection between the objects in the image.
So Google Lens understands context instead of simply identifying objects.
4. Text Detection
When Google Lens detects text in an image, it uses OCR, aka Optical Character Recognition technology. This technology helps it identify the text. Next, it identifies the words in the image. The fonts or their placement in the image do not matter.
Google Lens can understand multiple types of text, including the following:
- Printed Text
- Handwritten Notes
- Decorative Fonts
Even if this text is in multiple languages, Google Lens can identify them. Still, the original layout remains the same. Even if the text has headings, paragraphs, and tables, Google Lens does not make any changes whatsoever.
Once Google Lens deciphers the text in the image, users can convert it to different formats. Not just text formats, the text can be converted into audio. Users can use it to perform other tasks, such as calling someone or saving details.
5. Entry Recognition and Labeling
Once Google Lens detects objects and text in the image, it performs entry recognition. Entry recognition includes understanding the text and the objects it represents. This matches what the user’s camera captures, including the following:
- Products
- Locations
- Public Figures
- Animals
- Brands
- Concepts
In this way, entry recognition analyzes what the object means in real life instead of merely considering its appearance.
6. Connection to Google Knowledge Graph
When Google Lens identifies an object in an image, it compares the same with existing data on Google. In order to perform this complex task, it uses the Google Knowledge Graph. What is it? Simply put, it's a massive data repository that contains information about real-world objects and the relationships between them. Note that Google Lens does not search random web pages. It searches verified information. Below is how Google Knowledge Graph helps Google Lens.
- Identifies landmarks and provides key information about the objects.
- Recognizes products while highlighting key features/specifications.
- Understand relationships between countries, brands, and locations.
- Provide clear summaries of crucial information.
7. Web Index and Visual Search Matching
Scanning an image with Google Lens is not just a surface-level scan. It compares the object in the image with millions of images in Google’s database.
Step 1
The first step that Google Lens takes is converting the image into a digital fingerprint. This fingerprint provides detailed information about the product’s colors, patterns, and more.
Step 2
Secondly, Google Lens searches Google’s image and web database completely. This helps it find images similar to the ones being analyzed.
Step 3
Google uses smart ranking systems to determine the most useful machines. It looks for things such as the following:
- The degree of closeness between the matches.
- Popularity of the authenticity of the sources.
- Things people click on when they conduct searches.
Thanks to these steps, Google Lens can ensure the following:
- Find products similar to the ones scanned (not the exact match).
- Identify unknown objects by matching them with similar images on Google.
- Display shopping links, prices, and comparisons (from multiple websites).
8. Multimodal Understanding
Google Lens uses multimodal AI models that combine the following:
- Visual Data (images)
- Text Data (labels, captions, and OCR results)
- User Intent (Location, language, and past searches)
These actions help Google Lens understand:
- What is the product?
- What does it do?
- Where can one buy the product?
- What is the right way to use the product?
9. Real-Time Processing and Feedback
For live camera use
- Real-time updates to results as and when the camera moves.
- Dynamic score adjustment based on lighting.
- Highlights key elements on the screen.
All these actions happen in real-time. It acts like an assistant that has complete access to the user’s camera.
10. Learning and Continuous Improvement
Google Lens will improve its capabilities over time. This happens through the following:
- Aggregated User Interactions (Anonymized)
- Feedback Loops (results on which users tap/click)
- Retrains models using the new data
- Regional and Language Adaptation
The improved capabilities ensure that Google Lens delivers greater accuracy with:
- New Products
- Emerging Landmarks
- Different Languages and Scripts
