1. A method of evaluating a vehicle, the method comprising:

  • processing infrared data corresponding to at least one side of the vehicle acquired in a single pass of the vehicle using a computer system including at least one computing device to enhance a set of signal features in the infrared data and extract infrared wheel data corresponding to each of a plurality of wheels on the vehicle from the infrared data, wherein the processing uses at least one enhancement process selected from a group of enhancement processes based on at least one anomaly, the group of enhancement processes including;

    segmentation, fusion of multiple infrared images in the infrared data, edge detection within an infrared image in the infrared data, applying thresholding to assign a pixel in the infrared data to white or black, and feature detection of a wheel of the vehicle in the infrared data; and

    analyzing the infrared data to determine a presence of at least one anomaly; and

    providing a result of the analyzing for use by an inspection station.
