1. A method of processing an image of an object under test to be analyzed, the method comprising: acquiring an image of the object under test, the image having a frame with a preferred axis and comprising a number of pixels; identifying, by a processor, an indicia of the angle of the object under test within the image relative to the preferred axis, comprising: determining a number of edge pixels forming a number of sets of the edge pixels, the number of edge pixels being determined from a number of pixels of the image; determining a number of indicia candidate regions, each candidate region forming a polygon bounded by at least one of the number of sets of the edge pixels; and determining the indicia from at least two of the number of indicia candidate regions; and determining the angle between the preferred axis and the indicia; rotating the image by the negative value of the angle; performing the analysis on the object under test without rotating the image; and presenting a result of the analysis on a user device.
