Abstract: A video coder includes a processing resource and a non-transitory storage device containing instructions executable by the processing resource to compute a weighted Δ frame based on a saliency map and a Δ frame. The saliency map is to indicate the relative importance of each pixel in a current frame based on its perceptual significance. The Δ frame is to include differences between corresponding pixels in a current frame and a motion predicted frame.

Abstract: In some examples, a print cartridge includes a memory device comprising quantized coefficients derived from a lossy compression, at a selected step size, of a difference color table including a plurality of difference nodes in which each difference node represents a difference value that is a difference of a value of a node of a color table and a value of a corresponding node of a reference table, the quantized coefficients useable to produce a reconstructed difference color table including a first set of difference nodes each representing a difference value that is within an error threshold at the selected step size, and a second set of difference nodes each representing a difference value that is outside an error threshold at the selected step size. The memory device further comprises corrective information to correct the second set of difference nodes of the reconstructed difference color table.

Abstract: Methods for fabricating printed devices and monitoring one or more performance characteristics of the printed devices during their fabrication in a high-speed process. Such a method includes developing a physics-based model of at least a first component of the printed devices, fabricating the printed devices with the high-speed process using fabrication steps that comprise depositing the first components, acquiring a physical characteristic of a plurality of the first components of a plurality of the printed devices following the depositing of the first components, predicting a performance characteristic of the printed devices based on the physics-based model of the first component and the physical characteristic acquired of the plurality of the first components; and then modifying at least one of the fabrication steps performed during the fabricating of a subsequently-fabricated group of the printed devices to adjust the performance characteristic of the subsequently-fabricated group of the printed devices.

Abstract: In example implementations, a method executed by a processor is provided. The method determines an amount of video information that is lost in a video frame due to compression. A drift correction is applied to the video frame to add back a percentage of the amount of video information that is lost. The video frame is encoded with the drift correction.

Abstract: In an example, a method is described that includes dividing an input image into a plurality of strips, where each strip is smaller than a whole of the input image. A plurality of binary images is then generated, where each of the binary images corresponds to one of the strips. Connected component labeling is performed on the binary images, one binary image at a time. An object map for the input image is then generated based on the results of the connected component labeling.
