Flatbed Scanners: An Alternative Tool for Gathering Horticultural Data

Evaluation method of ordinary flatbed scanners for quantitative density analysis.

Slashpack: An Integrated Tool for Gathering and Managing Hypertext Data

Many interesting Web-based AI problems require the ability to collect, store and process large text datasets. To address this problem, we have developed Slashpack, an integrated toolkit for collecting and managing hypertext data. Currently, we are using Slashpack to study the effectiveness of tagging as a mechanism for organizing and searching blogs, and also to study community structure in the...

BeTelGeuse: a tool for Bluetooth data gathering

In ubiquitous computing, activity-related data is typically gathered using customized sensing equipment that give physiological measurements. Unfortunately, such systems are often proprietary or expensive to obtain. Recently, the decrease in the prices of Bluetooth chips has made Bluetooth sensors a viable alternative. In previous research, various systems for gathering data from Bluetooth sens...

ContextLogger2 - A Tool for Smartphone Data Gathering

Researchers often want to gather activity-related data available on mobile phones. Based on our experience with data collection in numerous field studies, we identified a number of requirements for a smartphone data logger, and set out to create logging software fulfilling those requirements. Our software—named ContextLogger2— now comes close to meeting the goals set for it. Furthermore, it has...

Photo Repair and 3D Structure from Flatbed Scanners

We introduce a technique that allows 3D information to be captured from a conventional flatbed scanner. The technique requires no hardware modification and allows untrained users to easily capture 3D datasets. Once captured, these datasets can be used for interactive relighting and enhancement of surface detail on physical objects. We have also found that the method can be used to scan and repa...
