Maps the values of the input image evenly in the intensity map such that the pixel values of the adjusted image is spread across the intensity map of the image container. The function adjusts of CUVI maps the intensities of the image between LOW_IN and HIGH_IN to the LOW_OUT and HIGH_OUT. By default all the values of the input images are mapped across the full intensity map.
Function
CuviStatus adjust(CuviImage& src,
const CuviScalar& LOW_IN=0.0f,
const CuviScalar& HIGH_IN=1.0f,
const CuviScalar& LOW_OUT=0.0f,
const CuviScalar& HIGH_OUT=1.0f,
const CuviStream& stream = CuviStream());

Input Image
|
| LOW_IN
|
const CuviScalar&
|
Values above this point are mapped. If it’s 0.5 than all the values in the input image between an intensity value of 50% and HIGH_IN are mapped in output
|
| HIGH_IN
|
const CuviScalar&
|
Values below this point are mapped.
|
| LOW_OUT
|
const CuviScalar&
|
Output image doesn’t use the values below this point from the intensity map
|
| HIGH_OUT
|
const CuviScalar&
|
Output image doesn’t use the values above this point from the intensity map
