Prostate Microscopic Image Segmentation
 Goals:
• To segment cancer cells from the prostate biopsy images.
• To extract object-level features such as mean intensity, area, perimeter, and
standard deviation of the mean intensity of the segmented histological objects.
 Brief Description:
The prostate cancer diagnosis done by pathologists is very subjective and relatively
slow since it heavily depends on the pathologists’ interpretation. In this project, we
try to use image processing technique to assist pathologists. Image segmentation is
the first step. Cancer cells are segmented from the biopsy images and then objectlevel features, such as mean intensity, area, perimeter, and standard deviation of
the mean intensity of the segmented histological objects, are extracted from
segmented histological objects. This can then be used together with metabolites as
features for tumor/non-tumor classification.

 Heights of achievements throughout the semester (bullet points)
▫ Segmented the cancer cells from a few images.
▫ Features are extracted from the segmentation.

methodology and results.
As an example, Figure 1 shows a prostate biopsy image with pathologist
circled cancer region.

Then the region is selected in the Leica software as shown in Figure 2(a). Cancer
cells are segmented and numbered as shown in Figure 2(b).

A few object-level features, such as mean intensity, area, and perimeter of the
segmented histological objects, are extracted from the segmentation as shown in
