Brief description of the subject
Most of the current screens, called LDR (Low Dynamic Range) screens, are not able to
render the lighting of the real scene as faithfully as we perceive it. The technology of these
devices does not allow the display of the wide dynamic range of colors and intensities of
this type of images, called HDR (High Dynamic Range) images. The computer graphics
community, the film and video game industry are actively working on this issue. Tone
mapping (or tone mapping) is one of the proposed solutions. This method seeks to reduce
the dynamics of HDR images so as to ensure the visualization of the images mapped on
LDR screens with the constraint of a rendering that is as faithful to the reality.

     The aim of this internship is to improve the developed tone mapping approach given
in reference [1]. Some parameters that have been selected empirically will be adjusted
according to the TMQI metric to enhance the quality of the tone mapped images [2].

Simulations will support the study.
