A system such as an autonomous vehicle’s perception system will identify and classify an obstruction in a field of view of an image capturing device. The system will receive a sequence of image frames from the image capturing device. For each of the image frames, the system will segment the image frame into a regions of interest (ROIs), and the system will use a classifier to assign a classification to each ROI. The classification indicates whether the ROI is clear or obstructed. The system will aggregate the classifications for each ROI to determine an aggregate classification. When an obstructed classification persists for a threshold number of image frames, the system will classify the image capturing device as obstructed, and it will generate a function request that, when executed, will cause a system of which the image capturing device is a component to perform a function.
