Gamma correction.

) |
Perform a gamma correction on a grayscale image.
[in] | I1 | : The first grayscale image. |
[out] | I2 | : The second grayscale image after gamma correction. |
[in] | gamma | : Gamma value. If equals to -1, use automatic Gamma correction based on a non-linear technique. If equals to -2, use automatic Gamma correction based on a logarithmic technique. If equals to -3, uses automatic Gamma correction based on classification. If equals to -4, uses automatic Gamma correction based on probabilistic. |
[in] | method | : The method to use: either GAMMA_MANUAL if the user wants to use a positive constant gamma factor, or one of the automatic method if gamma is negative. |
[in] | p_mask | : If different from nullptr, permits to indicate which points must be taken into account by setting them to true. |
