The complexities that this schematic description suggests can only be appreciated by considering particular types of analysis. Understanding conceptions of analysis is not simply a matter of attending to the use of the word ‘analysis’ and its cognates-or obvious equivalents in languages other than English, such as ‘analusis’ in Greek or ‘Analyse’ in German. Socratic definition is arguably a form of conceptual analysis, yet the term ‘analusis’ does not occur anywhere in Plato's dialogues (see Section 2 below). Nor, indeed, do we find it in Euclid's Elements, which is the classic text for understanding ancient Greek geometry: Euclid presupposed what came to be known as the method of analysis in presenting his proofs ‘synthetically’. In Latin, ‘resolutio’ was used to render the Greek word ‘analusis’, and although ‘resolution’ has a different range of meanings, it is often used synonymously with ‘analysis’ (see the supplementary section on Renaissance Philosophy). In Aristotelian syllogistic theory, and especially from the time of Descartes, forms of analysis have also involved ‘reduction’; and in early analytic philosophy it was ‘reduction’ that was seen as the goal of philosophical analysis (see especially the supplementary section on The Cambridge School of Analysis). Particularly, we will deal with the combination of several low dynamic range images of the same scene acquired with different exposure times, in order to create a HDR image. Most methods combine the radiance values instead of the usual color values of standard 8 bit per pixel and channel images. When using the radiance, the result obtained by a HDR method has to be converted into a standard representation, for visualization in common displays. There exists a wide literature on HDR imaging. ? ) is designed to diminish the contribution of under and over exposed pixels. Figure 1 displays some examples of weighting functions. In order to apply the weighted average in Equation (1), the image sequence needs to be static, that is, the objects in the scene do not move and the camera is fixed. This is not the case for many sequences, and the application of such methods introduces ghosting effects. While the application of the inverse transfer function permits to combine values acquired with different exposure, it is not adequate for taking care of noise. las
