Finds documents with exactly this word group, in exactly this word order and spelling (e.g. "employer branding").
Finds documents with both search terms (e.g. sales AND bonus).
Finds documents with one or the other search term (e.g. porsche OR volkswagen).
Finds documents with all search terms. Blank space is understood as AND (e.g. man robot production).
Finds documents with no appearance of the word behind NOT (e.g. ford NOT "harrison ford").
Finds documents where the search term is mentioned at least "n" times."n" may be any number (e.g. COUNT(gear)>8).
Finds documents with both search terms in any word order, permitting "n" words as a maximum distance between them. Best choose between 15 and 30 (e.g. NEAR(recruit, professionals, 20)).
Finds documents with the search term in word versions or composites. The asterisk * marks whether you wish them BEFORE, BEHIND, or BEFORE and BEHIND the search term (e.g. lightweight*, *lightweight, *lightweight*).
Finds documents with the search term in different spellings. "?" allows only one character (e.g. organi?ation).
Special characters are understood as AND (e.g. Miller Bros. & Sons).

Abstract

Typically, tone mapping operators are used to map luminance of high dynamic range (HDR) scenes to that of a displayable range. The goal of this study was to compare the performance of different uniform color spaces (CIELAB, ICTCP, and Jazbz) by integrating them into a tone mapping operator. The Contrast Limited Adaptive Histogram Equalization-based Tone Mapping Operator (CLAHE-TMO) was used here. For this purpose, the HDR radiance map of a given scene was first constructed from multiple exposures of the scene captured by using an ordinary RGB camera. The radiance map was then transformed to a uniform color space for the application of TMO on its lightness channel. A psychophysical experiment was conducted using pair comparison method to compare performance of different uniform color spaces. Tone mapped images were compared in four different contexts: preference, naturalness, contrast, and texture details. The experimental results are reported here.
