Calculating distance between two blobs in a binary image in microns

1. How do you find the distance between two points in an image?
2. How do you find the distance between pixels?

How do you find the distance between two points in an image?

By using the coordinates (x1, y1) representing the right most point on the triangle and coordinates (x2, y2) representing the top most point. We can use a^2 + b^2 = c^2 to determine the distance between two points.

How do you find the distance between pixels?

The bwdist function calculates the distance between each pixel that is set to off ( 0 ) and the nearest nonzero pixel for binary images. The bwdist function supports several distance metrics. The Euclidean distance is the straight-line distance between two pixels.
