ABSTRACT:
An image sensing system provide feature tone detection. A feature tone detection module receives illumination compensated pixel data. To perform feature tone identification the illumination compensated pixel data is transformed to a color space having hue and saturation and then compared against pre-selected ranges of hue and saturation. Noise filtering is performed using an erosion-dilation process. A bit code is used to identify pixels having a specified feature tone, such as a skin tone.
