Abstract: A system for determining whether a dataset including a plurality of cross-sectional images includes a predetermined feature is provided, the system including a first AI model to: receive a dataset including a plurality of cross-sectional images as an input, analyse the dataset to identify a subset of cross-sectional images of the dataset capable of including the predetermined feature, and output the subset; a second AI model to: receive a first cross-sectional image from the subset, analyse the first cross-sectional image to determine whether the first cross-sectional image includes the predetermined feature, and output an indication of whether the first cross-sectional image includes the predetermined feature; and a processor configured to: provide the dataset as an input to the first AI model, obtain the output subset from the first AI model, provide the first cross-sectional image from the subset as an input to the second AI model, obtain the output from the second AI model, and based on the output from th

Abstract: A system for identifying a potential altered image includes an image analysis unit to analyse an image and output a result indicating whether the image shows a predetermined feature and a processor to obtain a first output from the image analysis unit for an image that has a plurality of pixels each having a pixel value, obtain an altered version of the image by adjusting pixel values of up to a predetermined threshold amount of pixels in the image, obtain a second output from the image analysis unit for the altered version of the image, determine whether the second output is different to the first output, and identify that the image is a potential altered image in response to determining that the second output is different to the first output.
