The widespread availability of portable computing power and
inexpensive digital videocameras opens up new possibilities for helping
retailers in a number of markets. One example is in optical shops,
where a number of systems exist that facilitate eyeglasses selection.
These systems are now more necessary as the market is saturated with an
increasingly complex array of lenses, frames, coatings, tints,
photochromic and polarizing treatments, etc.
Research challenges encompass Computer Vision, Multimedia and
Human-Computer Interaction. Cost factors are also of importance for
widespread product acceptance. The low-cost system designed allows the
client to visualize different eyeglasses models on a computer or
projected screen. Glass models are true-color images obtained from real
models. The system is based on a homeostatic image control module (that
keeps the image relatively stable under illumination changes), a face
and eye detection module and a glass management module. The client can
also move the glasses to fit them to the face.
The selector works at 9.5fps using a PC and 2 cameras.
