Hi all,

Sorry to disturb you all with a same kind of question again. I want to find the Standard deviation of a image in matlab it can perform with command stdfilt . And the same thing can be perform in Fiji also.

To be very clear now I need to use this in my own java project. So I tried typical methods as follows

```
IJ.run(Imgage, "StandardDeviation", "block_radius_x=3 block_radius_y=3");
ij.IJ.runPlugIn(Imgage, "StandardDeviation", "block_radius_x=3 block_radius_y=3");
IJ.doCommand(ImgMutiplied, "StandardDeviation");
```

Finallyā¦!

`mpicbg.ij.plugin.StandardDeviation SD = new mpicbg.ij.plugin.StandardDeviation();`

`SD(Imgage);`

`mpicbg.ij.plugin.StandardDeviation SD = new mpicbg.ij.plugin.StandardDeviation();`

`SD.Image;`

When I use following methods no errors can be seen in the programme but the required action wont perform on the image.

```
IJ.run(Imgage, "StandardDeviation", "block_radius_x=3 block_radius_y=3");
ij.IJ.runPlugIn(Imgage, "StandardDeviation", "block_radius_x=3 block_radius_y=3");
IJ.doCommand(ImgMutiplied, "StandardDeviation");
```

But

**> Unrecognized command: āStandardDeviationā** message can be seen in the screen. Further I have set up the maven correctly and here is the .jar file which contain this class. Is there other ways of performing this task???

Further this action works very well in the Fiji . When we use following steps.

**

Plugins āŗ Integral Image Filters āŗ Standard Deviation

Hope some one can solve this matter.

Best regards.
