1. A real-time image transformation monitoring system for a display system, comprising:
at least one pixel buffer configured to:
receive at least one pixel dataset associated with a source image, each pixel dataset comprising one or more pixels of source image data;
append fiducial data associated with a current reference checksum to each pixel of the at least one pixel dataset, the current reference checksum associated with a current transformation map, the current transformation map associated with at least one transformation of the source image data by an output image processor;
and
store the at least one pixel dataset and the appended fiducial data;
and
at least one transformation monitor in communication with the pixel buffer, the transformation monitor configured to:
as the output image processor reads the at least one pixel dataset from the pixel buffer, extract from the at least one pixel dataset the fiducial data appended to each pixel;
incorporate the extracted fiducial data into a checksum calculation associated with the source image;
and
when the at least one transformation of the source image is complete, determine a system status by comparing the checksum calculation to the current reference checksum.
