Hybrid Image Creator

A novel technique for creating hybrid images
Schyns Illusion is a novel technique that takes advantage of the ability of the human visual system to separate information coming from different spatial frequency channels. Images are generated using two extremes of the spatial frequency spectrum; high frequencies carrying the fine detail and low frequencies conveying the shadows and gradual changes in the bright and dark parts of the image. These are then combined to create a hybrid image that changes depending on which spatial frequency band is interpreted.
By looking at a hybrid image from a normal viewing distance, the brain will interpret the high spatial frequencies of the image, with the result that the viewer fails to notice the different image hidden within. The other interpretation is only revealed by viewing the image from further away or by the viewer ‘squinting’ their eyes so that the high spatial frequencies are quieted and the blurred, low spatial frequencies in the image are interpreted.
Key Benefits
- Allows the creation of images that appear to change depending on the distance to the viewer
Applications
- Advertising
- Safety signage
- Architecture and interior design
- Clothing
- Security
Schyns Illusion involves the application of image processing techniques to generate a range of test images which are then assessed to determine the optimum frequency composition for the size of image. The IP is embodied in the know-how for this process.
