Abstract: Automatic font synthesis for modifying a local font to have an appearance that is visually similar to a source font is described. A font modification system receives an electronic document including the source font together with an indication of a font descriptor for the source font. The font descriptor includes information describing various font attributes for the source font, which define a visual appearance of the source font. Using the source font descriptor, the font modification system identifies a local font that is visually similar in appearance to the source font by comparing local font descriptors to the source font descriptor. A visually similar font is then synthesized by modifying glyph outlines of the local font to achieve the visual appearance defined by the source font descriptor. The synthesized font is then used to replace the source font and output in the electronic document at the computing device.

Abstract: An online system receives content items from a third party content provider. For each content item, the online system inputs an image into a neural network and extracts a feature vector from a hidden layer of the neural network. The online system compresses each feature vector by assigning a label to each feature value representing whether the feature value was above a threshold value.

For a new set of content items, the online system compares the compressed feature vectors of the content item with the user feature vector. The online system selects one or more of the new content items based on the comparison and sends the selected content items to the user.

Abstract: One embodiment of the present invention includes techniques for rasterizing geometries. First, a processing unit defines a bounding primitive that covers the geometry and does not include any internal edges. If the bounding primitive intersects any enabled clip plane, then the processing unit generates fragments to fill a current viewport. Alternatively, the processing unit generates fragments to fill the bounding primitive. Because the rasterized region includes no internal edges, conflation artifacts caused when the number of coverage samples per pixel exceeds the number of color samples per pixel may be reduced. In prior-art techniques, reducing such conflation artifacts typically involves increasing the number of color samples per pixel to equal the number of coverage samples per pixel.

For each encountered widget, layer allocation operations are performed which include selecting a current, previous, or next layer to which to allocate the widget and determining whether the selected layer can accommodate the widget, where a determination that the selected layer cannot accommodate the widget results in a bit from a stencil buffer being allocated to the selected layer.

The stencil test mask is written to the stencil buffer, and the layer allocation operations are repeated for each remaining widget.

Abstract: A general moving image includes a plurality of objects in a frame image. At the time of playback, the temporal visual characteristic is taken into consideration uniformly in the overall frame image. It is therefore impossible to perform playback while particularly considering an object of interest. In this invention, when playing back a moving image including a plurality of time-divided frame images, the object adaptation time of each object image is acquired first in the frame image of interest of the plurality of frame images. An adaptation weight is calculated based on the acquired object adaptation time, and a low-pass image reflecting the adaptation weight is generated for each object image. Color adaptation conversion using the low-pass image makes it possible to perform, for the frame image of interest, color conversion based on the adaptation time of each object image and perform color conversion particularly considering an object of interest.
