Hybrid Images

Theses images are the result of merging the high frequencies from one image with the low frequencies from another. These frequencies were extracted using Laplacian filters, which act as bandbass filters.

Extra Credit

The highest and lowest frequencies for this image are taken from a picture of albert Einstein. The frequencies in between are taken from a picture of Marilyn Monroe. From close up or very far away, Einstein's features are more apparent. From a medium distance, the image seems more like an image of Monroe.
The highest frequencies in these images are displayed in red, while medium and low frequencies are displayed in green and blue respectively. This gives the effect of red "highlights" to specific features.
This is the same image as the image at the top of this page, only the color channels are preserved in the highest frequencies. This makes the high frequency component of the image more noticeable close up, and doesn't seem to affect the appearance of the low frequency component at a distance. Overall, it makes the hybrid image illusion more convincing.
