rotate array 3x3

[pawhan11]

Hello,

I am doing some image processing algorithm

I ve defined 33 basic types of arrays like this:

1 0 0

1 x 1

1 1 1

1 0 0

1 x 0

0 1 0

 

where x does not matter

Then I need to take each pixel in binary image and check if surrounding pixels apply to one of this patterns

There is 256 possibilities of patterns.

I want to rotate basic arrays  in way that from

1 0 0

1 x 1

1 1 1

i can get:

1 0 0

1 x 1

1 1 1

 

1 1 0

1 x 0

1 1 1

 

1 1 1

1 x 0

1 1 0

 

1 1 1

1 x 1

1 0 0

 

1 1 1

1 x 1

0 0 1


1 1 1

0 x 1

0 1 1


0 1 1

0 x 1

1 1 1

I don't know what is faster, define base of 256 possibilities or rotate this 32 patterns in real time

Search the forums for "rotate array" for some posts about this.

I ve seen that.

i ve decided to do that in brutal way and it seems to be working

I don't know why you would pick a "brutal way" over a way that should be easier.

I'm not even sure how the VI you posted corrrelates with what you were looking for originally which was how to rotate a 3x3 element 2-D array.

Go with whatever feels like it works for you.  Good luck with your project.
