Claim One:
1. A process for recovering a vehicle, comprising: obtaining a red green blue (RGB) image comprising a target on a recovery device, wherein the RGB image is obtained from a camera operably coupled to the vehicle; receiving an input from a user designating a target hue value and a target luminance value; converting the RGB image to a hue value saturation (HSV) color model; splitting the HSV color model into a hue value plane and a luminance value plane; configuring a hue band pass filter and a luminance band pass filter with a hue threshold and a luminance threshold, respectively, wherein the configured hue band pass filter and the luminance band pass filter are applied to the hue value plane and the luminance value plane, respectively; combining the filtered hue value plane and the filtered luminance value planes to yield a plurality of potential target pixel groupings; determining the most probable target from the plurality of potential target pixels; and directing the vehicle to the center of said most probable target.
