Can't find best crop

[Dominique CLAUSE]

Hi !
Thanks for this amazing library. I use it to smart crop some thumbnails and a user of mine tried it to with the following image:

The purpose is to have it cropped to width: 450px, height 150px.
When using this tool: https://29a.ch/sandbox/2014/smartcrop/examples/testbed.html
I can see the preview works fine with a crop starting at 0x24. Notice the third one is a crop starting at 0x241.

In code though, all returned crops are:

What I don't understand is why I can't find the exact same best crop using the same code and the online photo. Are there some options I could use to make detection fit better ?

Can you link to an example of what you expect and what happens? I'm not sure I understand what you mean.
