Analytical imaging

The high intensity x-ray beams at synchrotron sources allow real-time tomography and other advances [298].

The most important properties of analytical images can be summarized as follows ... 

Multivariate analytical images may be processed additionally by chemo-metrical procedures, e.g., by exploratory data analysis, regression, classifica-tion> and principal component analysis (Geladi et al. [1992b]). 

For distribution analysis and analytical images the potential information amount increases by the factor A in case that all the distinguishable points (all the pixels or voxels, respectively) are analyzed. In the ideal case, it results in... 

MRI is an analytical imaging technique primarily used in medical settings in order to produce high-quality images of the insides of the human body. Nevertheless, food applications of the MRI technique have been developed... 

Decreasing the nanochannel width thus leads to qualitatively new and counterintuitive behavior that can be exploited for molecular separations. Because details of the flow profiles in individual nanochannels are below the resolution limit of optical microscopy, only the average velocities of dye fronts can be monitored. Significant improvements in the lateral resolution of analytical imaging methods are required to study the transport of molecules in an individual channel.

Automated processing and computerised measurement of analytical images can be employed to extract specific information very accurately and repro-ducibly. The processing of analytical images itself is mainly used for two main purposes (a) to improve the visual appearance of images for enhanced interpretation by a human observer (b) to prepare the images for quantitative measurement of the inherent features and structures. 

This chapter describes several applications of wavelet methods to analyse and process analytical images. A short list of online resources on wavelets and wavelet analysis with focus on their application to analytical images is included at the end of the chapter, together with an extensive bibliography on the subject and the names of the software programs used to process the images displayed in this study.
