Hi,

I studying OpenCV library for a few months now. And I encountered different ways to solve this problem (find an Image from a array of images)

I aware that the semantics is important. example:

  1. Find an image from DB of images that similar - use Img_Hash.
  2. Find an image from DB of images that Not similar - use Histogram.

Also, I see people advised to use features. (Its not the formal usecase to my understanding..)

Will be happy to hear opinions from any kind..

p.s : It's for general knowledge purposes..
