AI Technical Summary
Technical Problem
Existing image filtering methods on computing devices are inefficient and slow, particularly when detecting inappropriate content, especially for applications accessible to minors, and often require significant computational resources.
Method used
An on-device image classification model is applied to detect invalid images before reaching the user interface layer, replacing them with placeholders using a graphic pipeline, thereby saving computational resources and ensuring efficient and accurate filtering.
Benefits of technology
The method allows for rapid and precise identification of inappropriate images, such as those containing nudity, by processing placeholders instead of original images, thus conserving CPU resources and preventing display of inappropriate content.

Abstract
A method for filtering an image performed by a computing device The method comprises: applying an on-device image classification model to an image bitmap, wherein the image classification model is configured to detect whether the image bitmap corresponds to an invalid image; and upon detecting, by the image classification model, that the image bitmap corresponds to an invalid image, displaying, by a user interface, UI, an image placeholder.
