Abstract
Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, are disclosed for reducing the impact of lighting conditions and biometric distortions, while providing a low-computation solution for reasonably effective (low threshold) face recognition. In one aspect, the methods include processing a captured image of a face of a user seeking to access a resource by conforming a subset of the captured face image to a reference model. The reference model corresponds to a high information portion of human faces. The methods further include comparing the processed captured image to at least one target profile corresponding to a user associated with the resource, and selectively recognizing the user seeking access to the resource based on a result of said comparing.

1-20. (canceled)
An image processing method, the method comprising:
- determining a skin tone hue value;
- determining if each pixel's hue value in an image is within a radial distance from the skin tone hue value;
- for pixels that are not within the range, excluding the pixels' values from the image processing;
- for pixels that are within the range, increasing a score of each such pixel;
- performing facial recognition based on the remaining pixel scores.
A non-transitory machine readable storage device, storing program instructions that when executed cause an executing device to perform an image processing method, the method comprising:
- determining a skin tone hue value;
- determining if each pixel's hue value in an image is within a radial distance from the skin tone hue value;
- for pixels that are not within the range, excluding the pixels' values form the image processing;
- for pixels that are within the range, increasing a score of each such pixel;
- performing facial recognition based on the remaining pixel scores.
