Regions of interest for quality adjustments

A method comprising:

• identifying overlapping regions of interest in a picture;
• identifying non-overlapping regions of interest in the picture;
• calculating a quantization step size for the overlapping regions differently than for non-overlapping regions of interest;
• adjusting an encoder setting using at least the calculated quantization step size for the overlapping region;
• and
• encoding the picture using the encoder after the adjusting.

A computer-readable memory having instructions thereon for performing a method, the method comprising:

• identifying plural regions of interest for a picture, wherein the plural regions of interest comprise a first region of interest that overlaps at least in part with a second region of interest, wherein the first region of interest has first region-of-interest quantization step size information, and wherein the second region of interest has second region-of-interest quantization step size information;
• determining an overlap quantization setting for a portion of the picture that corresponds to the overlap;
• and
• adjusting quantization in the portion of the picture that corresponds to the overlap, wherein the adjusting is based at least in part on the overlap quantization setting.
