The message includes a subscriber identifier and one or more one or more first identifying attributes associated with a first media-work played-out by the subscriber. The server performs a first-level match between the first identifying attributes and unique identifiers included in a database. In response to the first-level match indicating that the first identifying attributes do not include any of unique identifiers, the server performs a second-level match, which compares the first identifying attributes to content attributes of different media-works linked to the unique identifiers. In response to the second-level match identifying one or more matching first identifying attributes to the content attributes that are linked to a particular unique identifier included in the database, the server selects enhanced content based on the particular unique identifier, and delivers that enhanced content to the subscriber.

In implementations of object-based color adjustment, an image editing system adjusts hue and saturation of a digital image so that objects in the digital image do not appear unnatural. The image editing system quantizes a CIELAB color space into classes that represent pairs of a and b channel values. The image editing system determines probabilities that pixels of a digital image belong to each of the classes, and based on the probabilities, determines a range of hue and a range of saturation for each pixel. An object detector segments objects in the digital image to determine ranges of hue and saturation for each segmented object. The image editing system selectively adjusts the hue and saturation for objects of the digital image based on whether the hue and saturation range for the object include a value of hue and saturation, respectively, selected in a user interface.

An image volume formed by plural anatomical images each having plural image slices of different imaging modalities is segmented by a 2D convolutional neural network (CNN). An individual anatomical image is preprocessed to form a mixed-context image by incorporating selected image slices from two adjacent anatomical images without any estimated image slice. The 2D CNN utilizes side information on multi-modal context and 3D spatial context to enhance segmentation accuracy while avoiding segmentation performance degradation due to artifacts in the estimated image slice. The 2D CNN is realized by a BASKET-NET model having plural levels from a highest level to a lowest level. The number of channels in most multi-channel feature maps of a level decreases monotonically from the highest level to the lowest level, allowing the highest level to be rich in low-level feature details for assisting finer segmentation of the individual anatomical image.
