gaussian filter

[subha123]

Hi,

  I want to implement gaussian function in an image without using NI VISION tool. so how I get the x and y value to implement this formula on that. 

here also I attached the block diagram of that.so please tell me which block help me to complete it.

Hello,

blur is achieved by convolving the discrete representation of the Gaussian distribution with the image. You do not need the Vision library for this:

Hi,

   Thank you sir for replying. I have some doubt how I find the lina image array which written in the picture you sent.

Hello,

this is just an example.

Use Graphics Format Pallete to read an image:

Hi, 

Thank you sir. Is there any link or video to understand properly the logic related to this image smoothing ,filterering using varrious algorithms?

please help me to find it.

Hi, 

Actually I use the NI labVIEW 2013 . So I face some difficulties to use the example.

Hello,

what dfficulties do you face? I use version 13.0 also.

Regarding the background behind convolution kernels and filters I suggest reading some literature. Search online for books, papers, etc... There is a lot of literature regarding this.
