Image comparison software (similarity and differences)

[akerkarprashant]

TL;DR

Image comparison softwares.

Images comparison
What are the best softwares available for comparing two images having similarity and differences?

Two photos each of Margaret and Enid.

1 Margaret's first photo with her second photo comparison.

2 Enid's first photo with her second photo comparision.

3 Margaret's first photo with Enid's first photo comparison.

4 Margaret's second photo with Enid's first photo comparison.

5 Enid's second photo with Margaret's first photo comparison.

6 Enid's second photo with Margaret's second photo comparison.

Example: Margaret Thatcher & Enid Blyton.

What you are looking for is facial recognition software.Here's a list of the best of 2021.

There is a huge difference between the two most common types of recognition.

1. You want to compare the current photo with a reference photo of the same person. "Is the person at the door the authorized employee he/she claims to be?"
2. You want to compare a photo with the universe of other faces. "Who is the criminal in this photo?"

You should be clear about which case you ask about.

Thanks.

Ignore the man image.

1 Comparison of Margaret's image with another image of her.

2 Comparison of Margaret's image with Enid's image.

3 Comparison of Enid's image with another image of her.

Spot out the similarity and differences in all the above three cases.

Do you (1)want software to do this or do you want to (2) learn how to make software to do this??

 

[akerkarprashant]

Thanks.

It can be either the case.

For general technical manipulation of images at a technical level I stilllike ImageJ. But it is nontrivial to use.

One more example of David Beckham.

You will need to be much more specific as to your requirements.

Both human faces?

Two eyes, nose, mouth?

Both David Beckham?

As @hutchphd said, be more specific.

 

[akerkarprashant]

Thanks.

Two eyes, nose, mouth , two ears, head hair on the face.

Two eyes, nose, mouth , two ears, head hair on the face.

That helps. It is much more specific. I suggest that you browse the results of the following search, for the term "image feature extraction."

Perhaps another PF member could recommend a textbook to help you learn that subject.

Facial recognition software looks at key points on a face, creates a lattice and generates a percentage of how close the image matches some known facial images.

Yes, but feature extraction is not the same as recognition. For example, red-eye photo correction requires finding the eyes.

 

[akerkarprashant]

Thank you.

Are there face feature extraction software applications available on the web?

You should have found some in the search from #12
https://duckduckgo.com/?q=image+feature+extraction&ia=web

Feature extraction software may not need to know if the feature is from a face or not a face. One exception might be red eyes. This search will show you some software.

Thanks.

Two more famous personalities images can be downloaded from the world wide web
for images comparision tracing similarities and differences.

Shammi Kapoor & Elvis Presley

The list could be endless.

Throughout this thread it has been very unclear what your interests really are. Face recognition? No. Feature extraction? No. Now I wonder if it is face morphing. Such as this.

Perhaps you want to morph a famous person's face to the face of a friend.

There are many software tools for that also.
