Abstract:
1. An image processor, comprising: an image receptor to receive an image, the image comprising care pixels and don't care pixels, identification of care pixels and don't care pixels being based, at least in part, upon a binary mask; and an image smoother to smooth the image by altering a value of at least one don't care pixel based, at least in part, on a weighted average of care pixels; wherein altering a value of at least one don't care pixel based, at least in part, on a weighted average of care pixels comprises: determining a first distance to a first care pixel and a first value of the first care pixel; determining a second distance to a second care pixel and a second value of the second care pixel; calculating a smoothed value for a don't care pixel based, at least in part, upon a weighted average of the first distance, the first value, the second distance and the second value, wherein calculation of the smoothed value of the don't care pixel is based, at least in part, upon the equation: where v is the smoothed value of the don't care pixel, v v d d altering the value of the don't care pixel based, at least in part, upon the calculated smoothed value.
