Inspecting dimension: bilat_param

Results of fitting several tone-mapped images to the generic operator. For each row: left the original tone-mapped image (left) and its fit with the generic TMO (right); middle - fitted tone-curve (red) and the scatter plot showing the relation between LDR/HDR luminance values; right - MTF of the fitted generic TMO. The blue vertical line indicates the Nyquist frequency, the black horizontal - the value 1 (no change), and the dotted curves - the base functions of the MTF.
