segmentación de imagen

Hola, quisiera saber como puedo procesar una imagen con Labview ya que necesito detectar un color en especifico en este caso el verde, la cantidad encontrada de células y el perímetro de las imágenes encontradas con ese color.

Muchas gracias por cualquier ayuda.

Do you have the vision toolkit or just plain LabVIEW? What is the file format of the picture? I think the vision tools have tools to do what you want (I don't use it, though, so I am not sure).

In plain LabVIEW (no toolkit), you can turn the image into a 2D array of RGB elements and split it into the R, G, and B channels, 8bits each.

Green would be defined by a large value in the G channel and much smaller values in the other two. You might want to optimize the threshold and ratios as needed. Using some convolution smoothing with a kernel size optimized for the typical object size you can eliminate the noise and turn things basically into a 0,1 array (1=green, 0=Not green). where you would count contiguous islands.

What have you tried?

Hi.

I have just plain labview, is the tollkit free to dowload?. I use the pictures from a program call Zen Pro 2012 Blue Edition (Carl Zeiss 2011) but I save the images in JPG format.

I´m a beginner right now, looking to create this program to make my investigation work easier because I have to count manually all cells.

Is it possible for me to get the perimeter of all cells and determine eliptical forms , from not eliptical?

Thank you in advanced.
