Color space processing
cuda::cvtColor
Converts an image from one color space to another.
3-channel color spaces (like HSV, XYZ, and so on) can be stored in a 4-channel image for better performance.
cuda::demosaicing
Converts an image from Bayer pattern to RGB or grayscale.
The function can do the following transformations:
-
Demosaicing using bilinear interpolation
-
COLOR_BayerBG2GRAY,COLOR_BayerGB2GRAY,COLOR_BayerRG2GRAY,COLOR_BayerGR2GRAY -
COLOR_BayerBG2BGR,COLOR_BayerGB2BGR,COLOR_BayerRG2BGR,COLOR_BayerGR2BGR
-
-
Demosaicing using Malvar-He-Cutler algorithm ([MHT2011])
-
COLOR_BayerBG2GRAY_MHT,COLOR_BayerGB2GRAY_MHT,COLOR_BayerRG2GRAY_MHT,COLOR_BayerGR2GRAY_MHT -
COLOR_BayerBG2BGR_MHT,COLOR_BayerGB2BGR_MHT,COLOR_BayerRG2BGR_MHT,COLOR_BayerGR2BGR_MHT
-
cuda::swapChannels
Exchanges the color channels of an image in-place.
The methods support arbitrary permutations of the original channels, including replication.
cuda::gammaCorrection
Routines for correcting image color gamma.
cuda::alphaComp
Composites two images using alpha opacity values contained in each image.
Note
- An example demonstrating the use of alphaComp can be found at opencv_source_code/samples/gpu/alpha_comp.cpp
