Abstract: The coding efficiency of predictive picture codecs using transform-based residual coding is enhanced by allowing the codec to switch between a set of transforms for the sake of the transform-based residual coding. It turned out that even when using explicit signaling from encoder to decoder in order to signal the actual transform to be used out of the set of transforms from encoder to decoder, an increase in coding efficiency may result. Alternatively, the switching between the set of transforms may be performed without explicit signaling at all, or using a combination of explicit signaling and some sort of prediction of the switching.

Abstract: A three dimensional (3D) printer generates 3D articles of manufacture through the selective hardening of light curable liquid resins. The 3D printer includes a vessel, a fixture, a movement mechanism, a light engine, a controllable pressure source, and a controller. The vessel contains light curable resin with a bottom portion including a transparent sheet. The light engine selectively illuminates a lower face of a 3D article of manufacture being formed through the transparent sheet. The fixture and movement mechanism selectively translate the lower face up and down which generates a varying pressure of the resin against a top surface of the transparent sheet. The controllable pressure source applies a gas pressure to a bottom surface of the transparent sheet to offset the varying pressure of the resin.
