Abstract: This disclosure provides methods, devices, and systems for image scaling. The present implementations more specifically relate to downscaling techniques that preserve a subset of pixel values in a digital image so that all reconstructed pixel values in the upscaled image can be interpolated based on two or more preserved pixel values. In some aspects, an image downscaler may partition a digital image into a number of image tiles based on a base tile size and one or more scaling factors associated with a downscaling operation used to downscale each image tile. The base tile size indicates the dimensions of the downscaled tiles. The one or more scaling factors indicate distances between the pixel values preserved as a result of one or more iterations, respectively, of the downscaling operation, where each iteration preserves a smaller subset of the pixel values from the original image (as a lower resolution tile).

Abstract: This disclosure provides methods, devices, and systems for video coding. The present implementations more specifically relate to hybrid coding techniques that combine aspects of inter-frame coding with aspects of intra-frame coding. In some aspects, a video encoder may perform inter-frame coding in a weighted manner so that the coded video frames (also referred to as “residual frames”) may include contributions from the current video frame to be transmitted over a communication channel and also may include contributions from the previous video frame transmitted over the communication channel. More specifically, any pixel value (r(n)) in the residual frame can be expressed as a weighted combination of a respective pixel value (x(n)) in the current video frame and a co-located pixel value (x(n?1)) in the previous video frame, where r(n)=x(n)??·x(n?1) and where 0???1 is a scaling factor representing the degree of contribution by the previous video frame.

Abstract: An embedding component is described which embeds information in a scanned document. The embedding component includes a document acquisition component, which acquires a scanned document from an associated scanning device. An information acquisition component acquires variable information associated with the scanned document. An encoding component generates a machine-readable representation of the variable information. A pattern insertion component uses the machine-readable representation to insert at least one machine readable pattern in the scanned document, to generate a modified document. An output component outputs the modified document to an associated output device, such that when the modified document is rendered on print media, the machine-readable pattern is not noticeable to the unaided eye of a person. A processor implements the document acquisition component, information acquisition component, encoding component, pattern insertion component, and output component.
