Google's Search by Image
While most people use Google to search for information by typing text, there’s an interesting feature called Search
by Image that allows you to search using an image instead of words. This feature relies on Computer Vision, a
technology that enables computers to interpret and analyse images.
When you upload an image to Google Search, the system uses Computer Vision Algorithms to analyse the
image. It extracts key features such as shapes, colours, textures, and patterns. This process is similar to how the
human brain identifies objects by recognising visual characteristics.
Next, Google compares these extracted features to its massive database of images collected from across the
Internet. Using advanced algorithms, such as image similarity search and pattern recognition, it identifies
matching or similar images.
Once the analysis is complete, Google displays search results that are related to the uploaded image. These results
may include:
• Information about the object or scene in the image
• Similar images
• Websites containing the image or related content
Computer Vision in Retail
In the world of shopping, both online and in physical stores, Computer Vision is being used more and more to
improve the shopping experience and make businesses more efficient. Retailers are using this technology to
understand customer behaviour, optimise store layouts, and provide better services.
