You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: SchlickTMO.m
    path of file: ./repos/HDR_Toolbox/source_code/Tmo
    
    the code of the file until where you have to start completion: function imgOut = SchlickTMO(img, s_mode, p, nBit, L0, k)
%
%       imgOut = SchlickTMO(img, s_mode, p, nBit, L0, k)
%
%
%       Input:
%           -img: input HDR image.
%           -s_mode: parameters selection: 'manual', 'automatic', and 'nonuniform'.
%           -p: a model parameter which takes values in [1,+inf].
%           -nBit: number of bit for the quantization step.
%           -L0: lowest value of the LDR monitor that can be perceived
%           by the HVS.
%           -k: a value in [0,1].
%
%       Output
%           -imgOut: tone mapped image
