Duplicate Image Finder "looks" at the photo content in order to find similarities. This is not something that a standard duplicate finder can do.
The tool is capable of finding similar photos and provides also an Image Search feature. Often referred to as "Reverse Image Search" it will let you find similar photos of one or more sample pictures.
The feature for finding similar images by sample is just one of the countless options of this professional photo organizer tool. Use the free download below to evaluate its true power. Organizing images is now a pleasure rather than an annoyance.
Your photos do not contain any EXIF description text after downloading them from your camera. If you are a professional photographer, tagging thousands of photos manually and adding descriptions is not an option. So if you had a wedding photo for example and wanted to find the rest from that photo-shoot you could not just type "Jane Smith Wedding" and find the rest. That is where a reverse image search comes in handy. Instead of typing a search string you use the photo as a search query. The tool will analyze your sample photo and search all the folders or drives that you have selected and list all similar images. Definitely there will be images in that photo-shoot that are similar to the one that you want to find.
Explained simply a similar image search is a form of search that uses a sample photo as a search query instead of text or voice keywords. That is to say, it uses the image characteristics of the sample photo as your input query.
For example, with Google Images you can quickly discover visually similar images on the web. Obtain also relative information about a photo including objects or places in it. Those may also include meta-data like the name of the object or location.
In technical terms, reverse picture search uses content-based image retrieval (CBIR). It is also known as query by image content (QBIC) and content-based visual information retrieval (CBVIR). It is also referenced as computer vision in retrieving digital images. That is what Google’s search by image does. Instead of guessing what keywords to use in order to find similar photos you just use a photo as your search query.
While identifying similar items is a simple task for a human being it is highly difficult for a computer. It requires heavy computations and advanced image analysis algorithms. While a human being can identify similar images better and easier it still takes time to look at the images and compare them. This is easy for several dozens of images but will cost you hours or days for even several thousand. If we speak for millions of images the task of identifying similar photos becomes impossible for a person.
Reverse image photo lookup can be used in many ways, Here are some things that you can do by searching for similar photos:
Use your portrait to find it on the Internet. If it was used as an avatar, all the web sites that contain it will be listed. You can easily identify if someone is trying to use your information to fake your identity.
Use an object photo to search the web for information. All sites containing similar images will be listed. You can acquire information about the object's features and properties or its price. You can also search for the name of a dog's breed for example by searching for its photo.
If you are designing something or need a slightly different photo to the one that you have you can use Google Reverse image search. It allows you to discover visually similar or related images to the one you have.
You may have an image with added text or other edits. You can use it to find the original unedited version on the web. You may also use the image to find its license or the author.
You can use Google reverse image search tool to find the websites where your photos are used. It is very easy to locate web sites that are using your photos without your permission or giving any credit. You can even see the count of websites that are using your photo.
By using a sample photo and finding web sites that plagiarize your work, you can ask them to link back to you in order to increase your SEO. Instead of asking them to remove your content, you can ask for a link back to your portfolio. This will help you to rank better on the search engines.
You can use a photo of a person to find his name. For example, use the photo of a celebrity to find his/her name and the movies that he/she plays in. Use a photo of a cat to find the breed that it belongs to. If you search with a photo of the Eiffel Tower, you will immediately be presented with information that it is located in Paris, France.
You may have a photo that is not of good quality or it is a small size. Use it to find all the versions of that photo available on the Internet. It is very likely to find a higher quality or even a better similar image.
There are countless things that you can do with a reverse-image search tool. The above are just a few examples.
