Question

Duplicate images

Hello, I am trying to delete any duplicate photos I have. I am using duplicate pro which I have had success but, I have noticed it still won't pick up some duplicates. For example I have two identical images, but they share no similar information on the properties tab, so I need a program that will identify the images just from the way it looks. Are there any programs that will do that. I am not that knowledgeable with computers so this is all I really know but will try to give you more info of what I can if you need it to help me. Many thanks Jen

Answer
And there is the problem.

It is entirely possible for two images to look nearly the same but not be found. Here's the scenario to create this problem.

Start with a mid sized image and now save it in all the formats. Try JPEG, BMP, TIFF and others.

My bet is no current duplicate finder will find those duplicates. Sorry folk, it will be a while till someone codes up such a duplicate finder.

date created

Thanks. Also just tried same date created (just discovered that they do share the same date and time exactly) So i ticked this in More duplicate options tab, but it still didn't find these two images that share same date which surprised me.

Until someone codes up a duplicate finder

That renders the images that the computer can use some AI to see if they are similar, what you are after only seems to exist in research and Google. Google has been working on image identification so they have methods beyond what you find in apps on PCs today. I won't get into what Google has been doing and only comment on what we run on our PCs and how to create the issue.

For now the duplicate finders rely on fast methods like, is the file the same size? OK, let's see if the image files are duplicate by comparing the file byte by byte.

No app today appears to use what we humans use to compare images. Some day we may get apps that do what humans do.

This is where we are today.
