Duplicate Image Finder - Find Similar Photos

Find Visually Similar Images - Organize Photos


Duplicate Image Finder - Overview


Duplicate Image Finder

Duplicate photo finder "looks" at your photos to find similarities. Find look-alike and duplicate images in a folder, computer, network, or find duplicates in Adobe Lightroom. Organize photos by eliminating useless repeating pictures - save valuable disk space. Identify similar and duplicate images even if they are edited, rotated, flipped, or color-corrected.

Specify percent of image similarity that will be used during the scan. It can broaden your results or specify exact match varying only in image format or size.

After the scan process is finished the program shows all the duplicate images in groups and can automatically mark the smaller resolution and/or smaller file size images to be delete - the lower quality ones.

Supports 40 popular image formats (including Photoshop/Lightroom PSD, TIFF, HEIC/HEIF, JPG, WebP...) and 300+ RAW camera photo formats(CRW, CR2, CR3, NEF, DNG...). Due to its innovative and optimized algorithms it is the fastest and the most precise duplicate photo finder on the market.

Duplicate Image Finder - Scan Modes



Duplicate Photo Finder

Finding visually similar images is unique feature, but the duplicate photo finder is a professions tool and provides extra scan modes like "100% Identical Files", "File Size", "EXIF Date/Time", "Similar EXIF".

Visual Compare - Find Similar Images

VSDIF uses advanced algorithms in order to compare images visually. This requires images to be loaded and analyze and that is why we provide support for so many image formats. The precision and performance of VSDIF is unmatched - it provides the best results and performance and is limited only by the resources in your system.

100% Identical Files - Find Duplicate Images

This mode will find only exact matches. These are only files with the same resolution and image format. This scan mode is convenient if you want to remove only the unaltered true duplicate photos. The advantage of using this mode is that it is very fast as no heavy visual processing is required.

File Size - Find Duplicate Images By Size

This is the fastest of all modes and looks only for files that have the same size. Though two files may have the same size and completely different content if you are comparing only certain file formats that is very unlikely.

EXIF Date/Time - Find Photos Shot In Close Time Intervals

This scan mode compares difference in shot time. It compares the actual date and time when the photo was taken - not its file date or time. You can set time difference in seconds between the shots. So if you set for example 60 seconds the tool will group together all the images that have less than 1 minute interval between the shots. This is very convenient as you can group items by time even if they are visually different.

Similar EXIF - Find Photos With Similar Or Duplicate EXIF Tags

As the name suggests this mode can find similar or exact match exif tags. For example you can find photos that have similar EXIF description. If you set the similarity to 100% the tool will list only the exact matches.

Compare Folders - Remove Duplicate Photos



Besides removing all duplicate images from a library VSDIF can also compare two or more folders for duplicate photos.

Exclude from self-scan
Exclude from auto-check

You can set a "source" folder in order to exclude it from auto-check and preserve the items inside. There is a per-folder option "Exclude from self-scan" which denotes that the items inside that "source" folder will not be compared with each other - they will be compared only with items from the other folders in the list. Read more on How To Exclude A Folder From Scan

There is also an "Exclude from auto-check" option which can be used separately or in combination with the "Exclude from self-scan option". Ticking the option for the corresponding folder denotes that the items inside will not be marked if the auto-check feature is used. Read more on How To Exclude A Folder From Auto-Check

The above options provide more flexibility, but if they seem too complicated for you, just use the option on the tool bar or in "File->Compare Folders". It lets you choose source and target folders and will set the above options automatically. Comparing folders for duplicates is extremely easy with Duplicate Photo Finder.

Duplicate Image Finder - Testimonials



Jon Canfield - PhotogrphyBlog.com

"Visual Similarity Duplicate Image Finder works very well and accurately. The ability to visually find duplicate photos, rather than just by filename will be useful to anyone that saves multiple versions of a file and needs to find all of them. The Search by sample image option is especially useful."

SnapFiles.com

Unlike traditional duplicate finders, this program `looks` at your images to determine whether they are duplicates or not and can find them even if the file name, format and size are different or the images have been rotated.



Duplicate Image Finder Automation - Corporate Library



Command-Line Parameters Usage: (Available only in Corporate Version)

DupImageFinder.exe -src_list <srclistfilename> -target_list <targetfilename> -log <logfilename> -s <similarity> -db <dbfilename> -p

-src_list <srclistfilename> - specifies a plain text file which contains image file names that you want to compare against <targetfilename> files
-target_list <targetfilename> - specifies a plain text file which contains image file names that you want to compare against <srclistfilename> files. If this parameter is omitted only the files inside <srclistfilename> will be compared against each other.

Note (new in version 2.5.0.1): if you omit -target_list parameter only -src_list files will be scanned

-log <logfilename> - specifies full path file name where the log from the comparison will be saved, e.g. c:\log.txt
-s <similarity> - specifies a similarity in percents. Example: -s 95
-db <dbfilename> - specifies the images cache file name without extension to be used or created. (see example below) ( "c:\any folder\cachefilename" )
-p - if this option is set then after scanning the project is auto-saved in the same folder as the log file

The command line parameters that are in bold are mandatory!

Information regarding errors and incorrect input can be found in the log file which is named "VSDIF_Log.txt" and generated in the "Documents" folder for the current user.


Starting from version 3.5.0.1 you could register the program using these command-line parameters:

-regname - specify your registration user name
-regcode - specify your registration code

Note: Cache files store images information gathered during the preprocessing pass (1st pass) of the scanning process. So if you often scan the same images, using cache file speeds up the preprocessing pass significantly.
You don't need to create the cache file. Just specify it as a parameter and the program will create it. If a cache file from previous scan exists the program will use it.

Example: DupImageFinder.exe -src_list "c:\src.txt" -target_list "c:\target.txt" -log "c:\log.txt" -s 95 -db "c:\cachefolder\cachename"

If you are using the FULL Corporate version you should run DupImageFinderDP.exe in order to use the command line parameters, if you are evaluating the DEMO then you should use DupImageFinder.exe as displayed in the example above.

This will find all images with similarity >= 95% and save their file names and similarity in c:\log.txt file

Note: If some of the parameters contain spaces, you must enclose them in double quotes. Example: -src_list "c:\program files\images.txt"

Please reference the help file for the most up to date information and example source and output file.
