Fast Blind Inverse Halftoning
We present a fast, non-iterative technique for producing grayscale images from error diffused and dithered halftones. The first stage of the algorithm consists of a Gaussian filte...

Hardware-Accelerated Rendering of Antialiased Shadows with Shadow Maps
We present a hardware-accelerated method for rendering high quality, antialiased shadows using the shadow map approach. Instead of relying on dedicated hardware support for shadow...
