create an image of dimension 3969 X 260

[KevinKM]

Hi all,

I want to create a 8-bit grayscale image of dimension 3969 X 600. Once the image is created i want to threshold the image using this coordinates (0,38) & (3968,38). 

Thanks in advance

Hello,

i fail to understand what do you mean by "I want to create a 8-bit grayscale image of dimension 3969 X 600. "? Do you mean you want to read the image into memory from the PC's hard drive?

Also, thresholding is not related to pixels location, but to the intensity levels in the image. Do you mean you want to extract the intensity values at the coordinates you've provided? And then threshold the image based on this?

Please explain your problem more clearly.

Best regards,

K

Hi Klemen,

Thanks form your reply,

Sorry if i was not clear about anything,

But i was able to create an image and threshold the image.

I am looking at something more,

I have an image which is obtained after subtracting 2 images.  I have attached the image to the post. I need to calculate the area, No of height pixels, and coordinates for the white objects.

Hi,

You need to threshold the image again to get the white particles. Then pass the thresholded image into imaq particle analysis and select area as the parameter. this will calculate the area of each particle. you can also explore other parameters in the imaq particle analysis to get the remaining features. 

I dont understand what is no of height pixelx? 

Can you cexplain that? 

Hope you can create the vi. 

Regards

Hi Folks,

Thanks for your replies. Its working fine now. I meant Bounding Rect Height for No of Height Pixels.
