Method and system for generating intrinsic images using a single reflectance technique
View Patent ↗An automated, computerized method is provided for processing an image. The method includes the steps of providing an image file depicting an image, in a computer memory, identifying a dominant region of single reflectance in the image and segregating the image into intrinsic images as a function of the dominant region of single reflectance.
1. An automated, computerized method for processing an image of a face, comprising the steps of:
providing an image file depicting an image of a face, in a computer memory;
identifying a dominant region of single reflectance in the image of the face wherein the step of identifying a dominant region of single reflectance in the image is carried out by performing a pixel stability analysis;
performing the pixel stability analysis as a function of pixel stability values relative to a threshold;
identifying a skin mask on the image of a face;
identifying eyebrow regions in the skin mask;
setting a first threshold for use in the pixel stability analysis as a function of pixel stability values relative to a threshold, for pixels in the skin mask;
setting a second threshold for use in the pixel stability analysis as a function of pixel stability values relative to a threshold, for pixels in the eyebrow regions; and
segregating the image into intrinsic images as a function of the dominant region of single reflectance.
2. A computer program product, disposed on a non-transitory computer readable media, the product including computer executable process steps operable to control a computer to:
provide an image file depicting an image of a face, in a computer memory,
identify a dominant region of single reflectance in the image wherein the process step to identify a dominant region of single reflectance in the image is carried out by performing a pixel stability analysis,
perform the pixel stability analysis as a function of pixel stability values relative to a threshold;
identify a skin mask on the image of a face;
identify eyebrow regions in the skin mask;
set a first threshold for use in the pixel stability analysis as a function of pixel stability values relative to a threshold, for pixels in the skin mask;
set a second threshold for use in the pixel stability analysis as a function of pixel stability values relative to a threshold, for pixels in the eyebrow regions, and
segregate the image into intrinsic images as a function of the dominant region of single reflectance.
