Luminance while imaging luminance meters measure luminance in a way similar to the way a digital camera records color images. Luminance Luminance is a photometric measure of the luminous intensity per unit area of light travelling in a given direction. It describes the amount of light that passes through, is emitted or reflected from a particular area, and falls within a given solid angle. The SI unit for luminance is candela per square metre (cd/m). A non-SI term for the same unit is the nit. The CGS unit of luminance is the stilb, which is equal to one candela per square
Measure space Measure space A measure space is a basic object of measure theory, a branch of mathematics that studies generalized notions of volumes. Measure spaces contain information about the underlying set, the subsets of said set that are feasible for measuring (the formula_1-algebra) and the method that is used for measuring (the measure). One important example of a measure space is a probability space. Measure space should not be confused with the related measurable spaces. A measure space is a triple formula_2 , where Set The formula_10-algebra on finite sets such as the one above is usually the power set, which
