Sony patents tool to spot flaws in AI-generated video frames
Sony has filed a patent for a system that checks for visual errors in video frames created by machine learning models. The tool compares a newly generated frame against a reference image to identify pixel-level differences, helping developers find defects in the output.
In the filing’s own words
To make it possible to easily check for an image defect in an estimated frame ( 24) output from a machine learning model ( 200). An image defect inspector ( 100) including at least one processor, wherein the at least one processor: acquires an n-th (where n is a natural number of 2 or greater) estimated frame ( 24) output from a machine learning model ( 200) by an n-th input frame ( 22) and (n−1)-th auxiliary information ( 28) related to features of first to (n− 1)-th input frames ( 22) being input to the machine learning model ( 200); acquires a predetermined comparison target frame; detects a difference related to pixel information of the n-th estimated frame ( 24) with respect to the comparison target frame, based on the n-th estimated frame ( 24) and the comparison target frame; and acquires image defect information of the n-th estimated frame ( 24), based on the difference related to the pixel information.
What exactly they claim (claim 1)
1. An image inspection system comprising: one or more processors; and one or more memories storing executable instructions thereon that, upon execution by the one or more processors, cause the image inspection system to at least acquire an n-th estimated frame output from a machine learning model, the n-th estimated frame being generated by the machine learning model by inputting an n-th input frame and (n−1)-th auxiliary information related to features of first to (n−1)-th input frames into the machine learning model; acquire a predetermined comparison target frame; detect a difference related to pixel information of the n-th estimated frame with respect to the predetermined comparison target frame, based on the n-th estimated frame and the predetermined comparison target frame; and acquire image defect information of the n-th estimated frame, based on the difference related to the pixel information, wherein n is a natural number greater than 1.
