Signal processing methods in color calibration
نویسندگان
چکیده
With the increasing use of desktop color scanners for digitizing color images it has become desirable to obtain device independent color information from these scanners. In order to achieve this goal the scanner spectral sensitivity needs to be estimated. This paper describes the application of signal processing techniques to the problem of estimating the scanner sensitivity. Results obtained by applying the methods described to an actual commercial scanner are presented and the performance of two different techniques is compared.

متن کاملOptical Moorings-of-Opportunity for Validation of Ocean Color Satellites
Buoy-mooring platforms are advantageous for time-series validation and vicarious calibration of ocean color satellites because of their high temporal resolution and ability to perform under adverse weather conditions. Bio-optical data collected on the Bermuda Testbed Mooring (BTM) were used for comparison with satellite ocean color data in an effort to further standardize sampling and data proc...
متن کاملVariation and Calibration Error in Electronic Imaging
In acquiring digital images, electronic systems not only detect optical signals but also convert them into a digital form for further image processing and exchange. Practical systems can introduce error during color calibration, and when acquiring image scene information. For large populations it is often assumed that the error can be modeled as a random variable having a zero mean. In the case...
متن کاملEnd-to-end color printer calibration by total least squares regression
Neugebauer modeling plays an important role in obtaining end-to-end device characterization profiles for halftone color printer calibration. This paper proposes total least square (TLS) regression methods to estimate the parameters of various Neugebauer models. Compared to the traditional least squares (LS) based methods, the TLS approach is physically more appropriate for the printer modeling ...

Flexibility of woven fabric structure has caused many errors in yarn location detection using customary methods of image processing. On this line, proposing an adaptive method with fabric image properties is concentrated to extract its parameters. In this regards, using meta-heuristic algorithms seems applicable to correspond extraction algorithm of structural parameters to the image conditions...
