Raising ACM's Digital Library
While the ability to find and access information remains a critical goal of the ACM Digital Library, it will move to a space in which interaction becomes a possibility. The space will contain people, datasets, software, simulations …DEPARTMENT: Letters to the Editor
Make Abstracts Communicate Results
ACM should make its publications communicate more effectively by insisting abstracts include a summary of results and key concepts, communicating important information even when readers skip or skim the rest.'As We May Think'
Despite the wonders of the human brain, it does not appear to have a convenient way to grow processing capacity while we can achieve that objective with our artificial computers by adding memory or adding processors.DEPARTMENT: BLOG@CACM

Technical Perspective: Image Processing Goes Back to Basics
In "Local Laplacian Filters," Paris et al. made a surprising move. They chose to build a system on the Laplacian pyramid, which is a very simple multiscale representation that predates wavelets.Local Laplacian Filters: Edge-Aware Image Processing with a Laplacian Pyramid
In this paper, we demonstrate that state-of-the-art edge-aware filters can be achieved with standard Laplacian pyramids.COLUMN: Last byte: Object Lessons
