Functions | |
| void | autoscaling (const Mat input, Mat &output) | 
| Given an input bgr or grayscale image, apply autoscaling on domain [0, 255] to increase the contrast of the input image and return the resulting image.  More... | |
| void | BIMEF (InputArray input, OutputArray output, float mu=0.5f, float a=-0.3293f, float b=1.1258f) | 
| Given an input color image, enhance low-light images using the BIMEF method ([288] [289]).  More... | |
| void | BIMEF (InputArray input, OutputArray output, float k, float mu, float a, float b) | 
| Given an input color image, enhance low-light images using the BIMEF method ([288] [289]).  More... | |
| void | contrastStretching (const Mat input, Mat &output, const int r1, const int s1, const int r2, const int s2) | 
| Given an input bgr or grayscale image, apply linear contrast stretching on domain [0, 255] and return the resulting image.  More... | |
| void | gammaCorrection (const Mat input, Mat &output, const float gamma) | 
| Given an input bgr or grayscale image and constant gamma, apply power-law transformation, a.k.a. gamma correction to the image on domain [0, 255] and return the resulting image.  More... | |
| void | logTransform (const Mat input, Mat &output) | 
| Given an input bgr or grayscale image and constant c, apply log transformation to the image on domain [0, 255] and return the resulting image.  More... | |
