Abstract: The present disclosure proposes an electromagnetic susceptibility (EMS) testing method based on computer-vision. The method includes a training stage and a testing stage. During the training stage, the electronic device receives a testing data and the monitor displays a first picture. A camera captures the first picture to generate a template video. The processor generates a plurality of template images at least according to the template video. During the testing stage, an antenna emits an interference signal to the electronic device. The electronic device receives the testing data and the monitor displays a second picture. The camera captures the second picture to generate a testing video. The processor generates a testing image according to the testing video and calculates a difference ratio between the testing image and each template image. The processor sends an alert signal when the difference ratio is greater than a threshold.

Abstract: A keyboard file verification method based on image processing comprises controlling a processor to perform following operations: obtaining a keyboard file; generating, according to the keyboard file, a search index and a feature image; obtaining a template image from a template database according to the search index; performing a calibration operation according to the feature image, wherein the calibration operation comprises: adjusting a resolution of the feature image according to a resolution of the template image; performing a shifting operation according to the feature image, to generate a plurality of candidate images; and comparing a key block of each of the plurality of candidate images with a key block of the template image to generate a difference map and a comparison result.
