Methods and systems for marking pixels for image monitoring

A computer readable storage medium containing instructions that when executed mark pixel data as being critical symbology pixel data to be displayed by a pixel on a display device, the instructions comprise:

• determine whether the pixel data is critical symbology pixel data;
• assign an intensity threshold level to the pixel data, the intensity threshold level based at least in part on a status of the pixel data as critical symbology pixel data;
• determine whether an intensity value of the pixel data is less than or equal to the assigned intensity threshold level;
• and
• mark the pixel data as being critical symbology pixel data when the intensity value of the pixel data is greater than the assigned intensity threshold level.

A computing device configured to:

• determine whether pixel data is critical symbology pixel data;
• assign an intensity threshold to the pixel data based at least in part on its status as a critical symbology pixel data;
• determine whether an intensity value of the pixel data is less than or equal to the assigned intensity threshold of the pixel data;
• and
• mark the pixel data as critical symbology pixel data when the intensity value of the pixel data is greater than the assigned intensity threshold.
