Image estimation by nonlinear projection - Extraction of eyeglass frame region and estimation of facial image from eyeglass facial image

摘要

This paper presents a new method of image estimation by nonlinear projection. We deal with eyeglass facial images and estimate eyeglass facial images by using basis vectors. In this case, the estimation accuracy depends on a gray value of pixels in eyeglass region. Therefore we extract an eyeglass region by using a parametric eyeglass model and replace the gray value of the pixels in the region. Then we estimate an eyeglassless facial images using the result image by former process which replaces the gray value. In this way we could improve the estimation accuracy.
