Function:Adjust

Adjust Image

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

CUVI_EXPORTS CuviStatus adjust(CuviImage* src, Cuvi32f LOW_IN=0, Cuvi32f HIGH_IN=1, Cuvi32f LOW_OUT=0, Cuvi32f HIGH_OUT=1);

Parameters

Name	Type	Description
src	CuviImage*	Input Image
LOW_IN	Cuvi32f	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	Cuvi32f	Values below this point are mapped
LOW_OUT	Cuvi32f	Output image doesn’t use the values below this point from the intensity map
HIGH_OUT	Cuvi32f	Output image doesn’t use the values above this point from the intensity map

Image Type Support
