Peaks Not Found by findpeaks()

Is there any way to find peaks rather than using findpeaks() function which didn't get the peaks of the attached curve?

To find peaks on an image, use imregionalmax().

Thanks!

I did so but when I used imshow() it showed the same image.

So what's wrong? I opened the documentation and there is no saying about the input's type to be RGB or binary image. In my case, it's binary though.

Like I said above I can't run your code until you attach the image. Can you do that? I'll check back later.

It’s apparently in the ‘Ezz El-din Abdullah Ic.mat’ file that I downloaded and then uploaded here by that name.

I’m deleting my Answer.

There's a bunch of stuff in there, but no IcRot variable. Here's what's there:

s = 
  struct with fields:

I've attached his code in test3.m.

[Ezz El-din Abdullah]

I'm sorry for not being clear.

It's Ic variable that is [93×361 uint8].
