摘要： An anomaly detection method of objects in a digital image is provided, wherein the image of the object is encoded and decoded by an autoencoder, then a pixel-wise difference is calculated between the input image of the object, and the reconstructed image of the object. Pixels whose pixel-wise difference is above a threshold are considered as dissimilar pixels, and the presence of clusters of dissimilar pixels is tested. A cluster of dissimilar pixel is considered as representing an anomaly.

摘要： A device that is able to generate a segmentation mask for an object in a digital image is provided. To do so, the device comprises a processing logic that is configured to use a previously trained auto-encoder to encode the image, and decode the image generating an additional alpha channel, which defines the segmentation mask.
