Every photo gallery on a device has similar images that take up unnecessary space. These pictures are created by editing software, while others result from clicking multiple shots. Therefore, comparing these images is a must to get rid of identical photos. However, manually identifying and removing similar photographs is not easy. The best way to do it is to use a similar image finder that makes the comparison less time-consuming and more effective. But before trying a third-party tool, if you want to do it yourself, we’ve covered that too.
Best Ways to Compare Images For Similarity
Multiple factors make images similar. For instance, two images clicked in the same frame at the exact location with a difference in focus. The same goes for multiple shots, where one picture focuses on something while the other is either blurry or has a different orientation.
Therefore, to compare images, multiple criteria must be kept in mind. Some of these are –
1. Picture quality.
2. Clarity of in-frame objects.
3. Orientation.
4. Timestamp.
5. Location.
6. Bitmap size of the image.
7. Details in a picture.
These seven criteria can help distinguish between photos and show similarities. However, comparing them manually can be a complicated task. Fortunately, there are ways to simplify the process. Check them out below!
Method 1. Differentiating Images Based on Time
It is an excellent way to sort images based on time. The sorting feature in your File Explorer helps get a segregated list of images based on the time. To clear things up, here’s a quick example –
- Go to the folder where images are saved.
- Right-click anywhere in the folder to find the View and Sort menu.
- Select Sort By > Date modified
- Depending on your choice, you can also choose the ascending or descending option.
This will sort the images. Now, go through each to realize which was clicked first and which is more detailed. Classifying pictures based on time gives an idea of which images were clicked in burst mode and which are substantially different.
Photos clicked in seconds and minutes seem to be more similar to what you would have captured later.
The only downside of this technique is that if you have modified the images after copying them on your PC, Windows considers the last modified time as the file origin date.
Method 2. Go Through Images to Compare Their Details
If you have a limited number of images, you can open all the photos one by one and compare them. It might seem a bit of a lengthy process, but it is effective. To make the process more efficient, use two image viewers and compare multiple photographs.
The sharpness, noise, and smoothness of your images matter a lot, and comparing images like this can take a lot of time and effort, which is not convenient. That is why it is recommended that you use the technique with limited pictures or when you have ample time.
Method 3. Use Third-Party Comparing Tool (Recommended)
