A Physical Sampling Metric for Image-based Computer Graphics

Computer models of the real world often use images of the environment to capture realistic visual complexity. Image-based modeling techniques permit the creation of geometric models with a high level of visual detail from photographs. These models are textured by resampling these images of the scene; we call this process image-based texturing. The problem with traditional image-based texturing ...

COMPUTER GRAPHICS OPTIQUE Optical Superposition of Projected Computer Graphics

We present some ideas and demonstrations for a hybrid projectorbased rendering and display technique we call Computer Graphics Optique. Instead of partially overlapping projected images to achieve a wide-area display, we completely overlap projected images on top of each other to achieve the addition of light and color in an “optical composition buffer.” The idea is to use the optical compositi...

PDEs in Computer Graphics

Colorization is a computer-assisted process of adding color to a monochrome image or movie. The process typically involves segmenting images into regions and tracking these regions across image sequences. Neither of these tasks can be performed reliably in practice; consequently, colorization requires considerable user intervention and remains a tedious, time-consuming, and expensive task. In t...
