Media position determination based on images of patterns captured by imaging sensors

A method comprising:

• receiving, by a processor, a first signal corresponding to an image of a pattern of features captured by an imaging sensor, the pattern of features being positioned at a spaced relation with respect to the imaging sensor and the features in the pattern of features being positioned at predetermined distances relative to each other;
• identifying, by the processor, first property values along the pattern of features;
• receiving, by the processor, a second signal corresponding to a second image captured by the imaging sensor;
• identifying, by the processor, from the second signal, second property values along the second image;
• determining, by the processor, whether the second property values differ from the first property values;
• and
• based on a determination that the second property values differ from the first property values, determining, by the processor, that a beginning of a media is positioned to be imaged by the imaging sensor.

A non-transitory computer readable medium on which is stored machine readable instructions that, when executed by a processor, cause the processor to:

• receive a first signal corresponding to an image of a pattern captured by an imaging sensor, the pattern being positioned at a spaced relation with respect to the imaging sensor;
• identify first scan windows in the first signal, the first scan windows being sections of the first signal correlating to respective positions of objects included in the pattern;
• identify, from the first signal in the first scan windows, first property values along the image of the pattern;
• receive a second signal corresponding to a second image captured by the imaging sensor;
• identify second scan windows in the second signal, the second scan windows being sections of the second signal correlating to the respective positions of the objects included in the pattern;
• identify, from the second signal in the second scan windows, second property values along the second image;
• determine whether the second property values differ from the first property values;
• and
• based on a determination that the second property values differ from the first property values, determine that a beginning of a media is positioned to be imaged by the imaging sensor.
