A computerized method of vehicle image comparison, comprising: obtaining an input image acquired by an imaging device capturing at least part of a vehicle; segmenting the input image into one or more input segments corresponding to one or more mechanical components comprised in the at least part of the vehicle using a segmentation model; retrieving a set of multiple reference images, wherein each reference image within the set comprises at least one reference segment corresponding to at least one input segment of the one or more input segments, thereby obtaining a respective set of multiple corresponding reference segments for each input segment of the at least one input segment; and generating at least one difference map corresponding to the at least one input segment, comprising, for each given input segment of the at least one input segment: comparing the given input segment respectively with each corresponding reference segment within the respective set of multiple corresponding reference segments thereof using a comparison model, giving rise to a set of multiple difference map candidates each indicating probability of presence of difference of interest between the given input segment and the corresponding reference segment, the DOI representative of physical change of the vehicle; and providing a difference map corresponding to the given input segment according to probability of each difference map candidate in the set of multiple difference map candidates, the difference map indicating probability of presence of DOI in the given input segment. obtaining an input image acquired by an imaging device capturing at least part of a vehicle; segmenting the input image into one or more input segments corresponding to one or more mechanical components comprised in the at least part of the vehicle using a segmentation model; retrieving a set of multiple reference images, wherein each reference image within the set comprises at least one reference segment corresponding to at least one input segment of the one or more input segments, thereby obtaining a respective set of multiple corresponding reference segments for each input segment of the at least one input segment; and generating at least one difference map corresponding to the at least one input segment, comprising, for each given input segment of the at least one input segment: comparing the given input segment respectively with each corresponding reference segment within the respective set of multiple corresponding reference segments thereof using a comparison model, giving rise to a set of multiple difference map candidates each indicating probability of presence of difference of interest between the given input segment and the corresponding reference segment, the DOI representative of physical change of the vehicle; and providing a difference map corresponding to the given input segment according to probability of each difference map candidate in the set of multiple difference map candidates, the difference map indicating probability of presence of DOI in the given input segment. comparing the given input segment respectively with each corresponding reference segment within the respective set of multiple corresponding reference segments thereof using a comparison model, giving rise to a set of multiple difference map candidates each indicating probability of presence of difference of interest between the given input segment and the corresponding reference segment, the DOI representative of physical change of the vehicle; and providing a difference map corresponding to the given input segment according to probability of each difference map candidate in the set of multiple difference map candidates, the difference map indicating probability of presence of DOI in the given input segment.
