Applies a luminance correction (initially High Dynamic Range (HDR) tone mapping)

outputToneMappedImage = obj.applyFastToneMapping(inputImage)

Input

• inputImage the input image to process RGB or gray levels.

Output

• outputToneMappedImage the output tone mapped image.

Using only the 2 local adaptation stages of the retina parvocellular channel: photoreceptors level and ganlion cells level. Spatio temporal filtering is applied but limited to temporal smoothing and eventually high frequencies attenuation. This is a lighter method than the one available using the regular cv.Retina.run method. It is then faster but it does not include complete temporal filtering nor retina spectral whitening. Then, it can have a more limited effect on images with a very high dynamic range. This is an adptation of the original still image HDR tone mapping algorithm of David Alleyson, Sabine Susstruck and Laurence Meylan's work, please cite [Meylan2007].
