Deviation magnification: revealing departures from ideal geometries

A system comprising:

• a processor;
• and
• a memory with computer code instructions stored therein, the memory operatively coupled to said processor such that the computer code instructions configure the processor to implement:
• fit a model of a geometry to digital input image;
• matte a region of the digital input image according to the model based on a sampling function;
• generate a deviation function based on the matted region, the deviation function representing a deviation of the matted region of the digital input image from the model;
• extrapolate the deviation function to an image wide warping field;
• and
• generate a digital output image by warping the digital input image according to the image wide warping field.

A non-transitory computer-readable medium configured to store instructions for analyzing an image, the instructions, when loaded and executed by a processor, causes the processor to:

• fit a model of a geometry to a digital input image;
• matte a region of the digital input image according to the model based on a sampling function;
• generate a deviation function based on the matted region, the deviation function representing a deviation of the matted region of the digital input image from the model;
• extrapolate the deviation function to an image wide warping field;
• and
• generate a digital output image by warping the digital input image according to the image wide warping field.
