1. A method executed by a system comprising a hardware processor, comprising
in response to determining that a number of samples of operation data indicative of a range of validity of an operation to be performed by the system on image data exceeds a threshold, dividing the samples of operation data into a plurality of chunks, wherein a chunk of the plurality of chunks includes multiple samples of operation data;
determining respective partial convex hulls for respective chunks of the plurality of chunks;
determining a convex hull for the operation data based on a sum of the partial convex hulls that joins the partial convex hulls to produce the convex hull for the operation data;
determining whether the image data exceeds the range of validity of the operation data based on the convex hull for the operation data; and
modify the operation performed by the system on the image data in response to determining that the image data exceeds the range of validity of the operation data.
