Colorimetric analysis of soil with flatbed scanners

Evaluation method of ordinary flatbed scanners for quantitative density analysis.

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...

Polynomial modeling and optimization for colorimetric characterization of scanners

In this work we present different computational strategies for colorimetric characterization of scanners using multidimensional polynomials. The designed strategies allow us to determine the coefficients of an a priori fixed polynomial taking into account different color error statistics. Moreover, since there is no clear relationship between the polynomial chosen for the characterization and t...

Using Flatbed Scanners to Collect High-resolution Time-lapsed Images of the Arabidopsis Root Gravitropic Response

Research efforts in biology increasingly require use of methodologies that enable high-volume collection of high-resolution data. A challenge laboratories can face is the development and attainment of these methods. Observation of phenotypes in a process of interest is a typical objective of research labs studying gene function and this is often achieved through image capture. A particular proc...

A study of GafChromic XR Type R film response with reflective‐type densitometers and economical flatbed scanners

The GafChromic XR Type R film is a relatively new product for recording high radiation dose in interventional radiological procedures. Means of measuring the film response were studied in this investigation. Two handheld reflective-type densitometers of different models were compared in the range of 0-8 Gy. They were found to be in excellent agreement. Five reflective flatbed scanners of differ...
