Plugin update: Parallel Spectral and Iterative Deconvolution

Piotr Wendykier
Hello,

I have updated my plugins for spectral and iterative deconvolution.
No new features have been added, but both plugins work a little faster
due to improvements in Parallel Colt.
Moreover, on my website you can now find the following benchmarks:
- Parallel Spectral Deconvolution 1.6 vs DeconvolutionJ
- Parallel Iterative Deconvolution 1.6 vs Iterative Deconvolve 3D

The plugins are available at:

questions on Dynamic Threshold_1d

Chengxin Li
Hi

I tried Gary's Dynamic Threshold plugin. I have some questions on this plugin,

1. What's the differences between Median and (Max+Min)/2 ?
2. What does MaxMin mean ? And what does Mask Size mean ?
3. According to http://www.dai.ed.ac.uk/HIPR2/adpthrsh.htm, there is (Mean-C) solution. Which one in the plugin matching to this (Mean-C) ?

Thanks,

Chengxin

Hi Chengxin

If you have a gray scale image with these 3 pixels: 10, 2, 254.

The Median is the value that you get if you order all your gray values
sequentially: 2, 10, 254 and take the middle one. Here it is 10.

(Max+Min)/2 = (254 + 2)/2 = 128

The idea of Adaptive Thresholding is that you do the thresholding
operation in each square of a grid instead of globally.
I think that Mask is the size of a local square in the grid.
