RECOGNIZING DAMAGE THROUGH IMAGE ANALYSIS

Abstract:

Implementations of this specification provide for recognizing damage through image analysis. An example method includes obtaining a marked picture, the marked picture including one or more damage mark boxes, each damage mark box framing a respective portion of the marked picture depicting a damaged object; using a damage detection model to predict at least one damage prediction region in the marked picture, the at least one damage prediction region including a first damage prediction region; determining a location loss term related to a location deviation in a loss function for a current prediction, including determining whether any of the one or more damage mark boxes fully encompasses the first damage prediction region; and updating the damage detection model based on the loss function, such that the damage detection model is adjusted to reduce deviations between damage mark boxes and damage prediction regions.
