Image Analysis

Image Analysis

• Carey Hammel and Mike Bruder

2
Problem

• What are the sizes of crystals that can be viewed
  through a microscope?

3
Hypothesis

• It should be possible to take pictures with the
  computer and then analyze the image.

4
Procedure

• First we used the L2001 Image Analyzer, it
  includes a CCD digital camera and a special
  program. We could get a still picture from this
  but never got any measurements.

5
Procedure

• Then we used the Flex-Cam and took pictures from
  the microscope, and from there they would be on
  computer.

6
Procedure

• With the pictures, we figured out how big they
  were in the microscope.
• At 100X the pictures were 2mm across
• At 400x the pictures were .2mm across

7
Results

• Knowing the size of the pictures we could
  measure the sides of the crystals. Some of the
  best crystals are the Silver Nitrate ones.

Conclusions

• Our Conclusions are that it is possible to find
  the size of crystals using a simple computer and
  paint program. Your results would probably be
  much better if you used something advanced like
  the L2001.

Conclusions

• With any crystals we viewed on the microscope, we
  could put them on the computer and measure their
  size. We might have had more results if we would
  have had better crystals with different
  variations.
