I am new to this platform.

I am developing application where I already have 100 images previously stored and want to compare image which I take from camera and see it that image matched with from existing 100 images.

I searched a lot and found OpenCV framework, bit is doesn't seems to be helping me on this.

Any help on suggestion will be really helpful.

Thanks in advance

Answer 1

OpenCV should be your best option. If you are looking for just image comparison, and just don't care about specific part of your image, then you can use Histogram Comparison

If you want to get in detail like objects, you can use feature detection and then comparing features. This method should be faster. However, I've read about combination of both methods like comparing feature points using histogram comparison.
