TLDR
An image processing application employs the concept of integral premultiplied alpha channel, and combines the techniques of multi-resolution representation, graph-structured representation, and automatic and intelligent data type conversion in order to permit a computer user to mix and manipulate both raster and vector based images in a single user interface while remaining unaware of the different data types underlying the images as discussed by the authors.Abstract:

TL;DR: In this article, the authors propose a color generator for generating data defining, independently of the image contact data, the color of each pixel of each image or combinations of images as defined by a user.
Patent
Image generator using a graphical flow diagram with automatic generation of output windows
TL;DR: In this paper, a graphics editor generates an Appearance Construction Graph (ACG) which represents an image formation process as a Directed Acyclic Graph (DAG) and allows complex graphics images to be constructed in a straightforward manner.
Patent
Method and apparatus for rendering of fractional pixel lists for anti-aliasing and transparency
TL;DR: In this article, a system for rendering visual images that combines sophisticated anti-aliasing and pixel blending techniques with control pipelining in hardware embodiment is presented, where a highly-parallel rendering pipeline performs sophisticated polygon edge interpolation, pixel blending and pixel rendering operations in hardware.
