01 Apr 2013 Fast 2D peak finder Find local maxima \ peak positions in noisy 2D arrays Author: natan

@Sujay, as the code documentation say in line 8: "The 2D data raw image - assumes a Double\Single-precision ... or unit16 array. Please note that the code casts the raw image to uint16, if your image is 8-bit depth, I recommend to change all the places that uint16 is used to uint8 for faster run times." So, either use FastPeakFind(uint16(image),...) or change all uint16 to uint8 in the code. In future updates I'll include this feature automatically.

This file looked interesting so I gave it a shot, unfortunately I get the following error when trying to run run_me.m:

Error using analoginput (line 46)
To learn about using data acquisition devices on the win64 platform, see the documentation on the session-based
interface.

Error in run_me (line 7)
ai = analoginput('winsound');

08 May 2013 Fast 2D peak finder Find local maxima \ peak positions in noisy 2D arrays Author: natan Voronov, Roman

please add the option to get a 2d bw mask of the peaks, in addition to the awkward coordinate vector ...

Thanks. it works well.

I have a 512x512 .tif image that I can read in matlab as, A=imread(''). I am trying to use this program as,
FastPeakFind(A). It is showing the following error:
??? Error using ==> times
Integers can only be combined with integers of the same
class, or scalar doubles.

Error in ==> FastPeakFind at 81
d=d.*uint16(d>threshold);

What is wrong?

Great algorithm and pretty fast. Thanks !!!!
