labview image processing

[pavannikam2589]

hi, i am doing project of recognition and classification of cancer cells by image processing and LabVIEW...can anybody help me to understand how to measure diameter of cell images by using edge detection?

Hello,

do you have any example images? Since it is a microscopic image, you want to obtain the radius in pixels, right?And classify them according to the diameter later on? Diameter suggest that your cells are always circular.

For example if your cells are white on a black background, you can first threshold the image and then count the objects (cells) using morphology. There are functions (for example count objects) that return the the area of the mask(s) - the cells. You can then calculate the diameters using the equation: A = pi*r*r -> d = sqrt(A/pi)*2.

Do you need to use edge detection?

Best regards,
