1. A method, with an information processing system, for detecting objects in a digital image, the method comprising:

  • receiving at least positional data associated with a vehicle;

    obtaining geographical information associated with the positional data;

    determining, based on the geographical information, a probability of detecting an object of interest within a corresponding geographic area associated with the vehicle;

    comparing the probability to a given threshold;

    in response to the probability being one of above and equal to the given threshold, performing the following;

    receiving at least one image representing at least one frame of a video sequence of an external environment of the vehicle;

    identifying a set of environmental conditions associated with the geographic area;

    selecting an illumination model based on the set of environmental conditions;

    retrieving at least one object template associated with the object of interest;

    selecting an object appearance model based on the set of environmental conditions;

    processing the at least one object template with respect to the illumination model and the object appearance model;

    analyzing the at least one frame of a video sequence with respect to the at least one object template that has been processed; and

    determining, based on the analyzing, if the at least one frame of a video sequence comprises the object of interest.
