What is a reverse image search?
1. Searching for images based on a source image
A reverse image search sources similar images based on an image uploaded to a search engine. Reverse image searches are also referred to as searching for a similar image.
A visual search engine examines the submitted image for color, shape, texture, or topography, based on algorithms. Reverse image searches can track the location of the source image, track sites where the image is used, and retrieve information about the image.
A reverse image search is not based on entered keywords, such as house, or building. Rather, we submit an image of our liking to the search engine and request to view similar images, without entering prompts or descriptions.
Let’s take a look at Google’s reverse image search engine.
On Google’s image search page, we can access the Search by image feature, by clicking on the camera icon in the search bar.
Next, a screen prompt asks for dragging or uploading an image, or posting a url link to an online image.
After we uploaded an image, Google Lens instantaneously rolls out image usages and variations of similar images.
2. How well does Google Lens match the image?
Let’s explore a reverse image search of the Brooklyn Bridge. I’m uploading an image sourced on Unsplash.com, an image library powered by creators everywhere. Most Unsplash images are available for free usage. However, do give full credit to the creator when using their images.
I choose an image by Jialin Hu and drop the image into Google’s search engine window.
The result is spot on.
