WEEK 12 FYP 2

Title:
Combining method 3 coding with GUI

Objective:

To combine and finalize the coding and GUI for Method 2: Discrete Cosine Transformation

Content/Result:

After I completing the coding process and GUI, now I combined it together to show the output which contains the original image and the stego image by using Discrete Cosine Transformation method. Below is the full programmed for Discrete Cosine Transformation method. The "Ninja Turtle" image is the original image. The "Boy" is the secret image that need to be hide. When the "Ninja Turtle" is embedded, its contains the secret image in it.

Conclusion:

After applying the coding, the changes at the low frequencies (top left corner) of the cover image is a little obvious. This is because I focuses and hide the hidden image in the low frequencies and ignoring the high frequencies of it. Although it is obvious, somehow human visible vision did not aware of the changes.
