Strong inter- channel correlation of that signal, unacceptable for some applications, is shown. Therefore, some kind of RGB color space transform is required to decrease this correlation. Only the Karhunen-Loeve transform (KLT) secures compete decorrelation. However, possible applications of this method are limited by the fact that coefficients of transform matrix must be calculated for each image separately. In the paper details of effective implementation such transform of color images are described. The examples of KLT applications in the field of color image processing are quoted. Using the standard color images, principal properties of KLT are shown, i.e. a complete decorrelation of color components and energy compaction in first components. This paper present also an approach that allows determining KLT coefficients that are constant for certain class of images and guarantee complete decorrelation simultaneously. A methodology for finding these coefficients is briefly described and some remarks on criteria of image selection for this class are made.","PeriodicalId":405495,"journal":{"name":"Optoelectronic and Electronic Sensors","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114507099","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The measuring head consists of three coils with separated leads. Coils are fixed perpendicularly one to the other. Coil output voltages are synchronously sampled and the input samples are processed according to the algorithm developed. The characteristic curve of the transducer is theoretically deduced. Algorithm fixing signs of currently reproduced output samples of reconstructed shape wave is commented. Most significant uncertainty sources of the circuit thrust by essential blocks of signal processing path are analyzed. It was confirmed by simulation that the reconstructed wave shape and calculated induction value are independent of angle setting of measuring head in magnetic field. The transducer sensitivity to the angle setting in the magnetic field is very small.","PeriodicalId":405495,"journal":{"name":"Optoelectronic and Electronic Sensors","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126271218","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
