is "image" a photographic picture or a computer backup?
If it is about photos, I am sad to say no-one has really made an effort the last couple of years => there is almost nothing! I use the old Bolide Image Comparer, but 1) I would like something new and fancy to replace it, and 2) it doesn't seem to be maintained, so it may not be worth the money to new customers.
I've used Visipics for comparing small images (homemade icons). It's okay.

I believe what you're asking for is a Reverse Image Search for your computer: select one, find all similar.
If so, you're probably out of luck.


out of luck is kaputt ?¿?¿?¿

I use http://www.duplicate-finder.com/photo.html quite a bit, and find the similarity percentage helpful in sorting.


Eh I just posted about this in Coding Snacks as somebody brought it up on another form this week. Bit much for Snacks I think but don't ask don't get etc...
I agree anyway, I'm surprised if there isn't already something out there that does this. Tineye etc for local hard drives, would be great.
Duplicate finders ... yes but the trouble is that they will throw up a list of all duplicates, not just the ones that relate to the pic you're working with. Unless, I thought, the finder has an option to ONLY show cross-directory duplicates in which case you just copy your pic on its own to a New Folder and then compare that with your pictures directory.
Visipics I like a lot but it doesn't do cross-directory comparison full stop. Or not for me anyway. Also, try grayscaling a picture and see if Visi flags it as a duplicate (it doesn't). Anti Twin on the other hand does.
So for a thorough duplicate search I would use two or three different searchers as they all have strengths and weaknesses.
There's also a tempting looking prog called Photology which claims to be able to search by "simple and intuitive filters like faces, sky, color, location, and time of day". Photology
I downloaded it ages ago but still haven't got around to trying it out yet. It apparently works by indexing all your pics by some criteria or other and then ... don't know :-)

option to compare an image selected with any other similar in my pc.

I followed your link but I can only see payware and trials there?
Must admit though that this bit - "automatically selects the best shot" puts me off a bit. I don't much like software doing anything automatically for me.



What is IFSS?
Image Forensic Search System (IFSS) is free, open source software for image searching. It allows you to
- search a target image within another image, or
- search images that are similar to a target image.
The main motivation behind the development of the IFSS software was to assist law enforcement agencies and similar organisations when they need to find whether a particular image (which they already possess) is stored in the typically thousands of images on a hard disk. For example, the police may have an image showing illegal activity of some kind, and wish to automatically search a seized hard disk to see whether the image is on that hard disk.
The IFSS software uses a simple 'wizard' so the user can quickly choose the source image, type of search, search parameters, and which folder to start searching in.
The two types of search are
- a search for images which are similar to the source image presented to the system, and
- a search for the source image inside other images, commonly called image within image search.
