(cel4)

The original image.

(cel4thr1)

Result of thresholding cel4 so as to retain (as foreground) pixel values originally in the intensity band: 0 - 150.

(cel4lab1)

Result of connected components labeling cel4thr1.

(cel4thr2)

Result of thresholding cel4 so as to retain (as foreground) pixel values originally in the intensity band: 130 - 150.

(cel4thr3)

Result of thresholding cel4 at a value of 210.

(cel4opn1)

Result of opening cel4thr3 using an 11 pixel circular structuring element.

(cel4opn2)

Result of opening cel4thr3 using a 7 pixel circular structuring element.
