We describe a method for converting conventional threechannel flatbed scanners into colorimeters. The method is based on the simple idea of placing a color filter between the image and the scanner sensors and making an additional scan.

DETECHIP ® is a molecular sensing array used for identification of a large variety of substances. Previous methodology for the analysis of DETECHIP ® used human vision to distinguish color changes induced by the presence of the analyte of interest. This paper describes several analysis techniques using digital images of DETECHIP ® . Both a digital camera and flatbed desktop photo scanner were u...

We present a system to measure 3D shape of sole surface of human foot using flatbed scanner. Our goal is to build a low cost system for reconstructing sole surface of human foot using flatbed scanner for making tailored shoes. There are two main phases in our system: a photometric parameter estimation and a reconstruction phase. The photometric parameter estimation calculates the position of th...

The purpose of this study was to quantify the performance and assess the utility of two different types of scanners for radiochromic EBT film dosimetry: a commercial flatbed document scanner and a widely used radiographic film scanner. We evaluated the Epson Perfection V700 Photo flatbed scanner and the Vidar VXR Dosimetry Pro Advantage scanner as measurement devices for radiochromic EBT film. ...

introduction: gafchromic ebt films are one of the self-developing and modern films commercially available for dosimetric verification of treatment planning systems (tpss). their high spatial resolution, low energy dependence and near-tissue equivalence make them suitable for verification of dose distributions in radiation therapy. this study was designed to evaluate the dosimetric parameters of...

Apricot stones have high commercial value and can be used for manufacturing functional foods, cosmetic products, active carbon, biodiesel. The optimal processing of the is dependent on cultivar there a need methods to sort among different cultivars (which are often mixed in facilities). This study investigates effectiveness two low-cost colour imaging systems coupled with supervised learning de...
