Maybe something like this?

 

(if you expect a large number, insert a to-I32 before taking the sum.)

hanks

i will try to do this

because my object is to  calculate the percentage of pixel in image like the function in NI vision builder 'count pixels) but in labview they don't have function to do this .

so i transforme the image To2D array.and count numbers between min and max and finaly calculate the percentage 

[altenbach]

The total number of elements is just the product of the two dimension sizes, so calcuating the percentage is very simple.

thanks

i will try to do

and if you cant send me this vi because i don't know the name of all the function in your image 

I student is the first time I am working with labview

As a student, this is a good opportunity to learn:

The functions are:

• In range and coerce
• Boolean to (0,1)
• To I32
• Add array elements
• Multiply
• Divide
• Array size
• Multiply Array Elements

Use "quickdrop" and start typing these words to get each function. If you don't know what quickdrop is, do a search. 😧

Good luck!
