Function:BitConversion

Converts image pixel values from one data type to another. It uses dataBits field of CuviImage to decide the number of bits of the destination image while the destination CuviImage decides the container. For example we want to convert an 8-bit input image to 15-bit image than the dataBits field of destination image will be 15 and container/datatype of destination image will be 16.

Function

CuviStatus bitConversion(CuviImage* srcImage, CuviImage* dstImage, CuviStream* stream = NULL);

Parameters

Name	Type	Description
srcImage	CuviImage*	Input Image
dstImage	CuviImage*	Output Image
stream	CuviStream*	GPU stream ID for execution

Image Type Support

Input	Output
8u	8u
8u	16u
16u	16u
16u	8u

Sample

Error creating thumbnail: Unable to save thumbnail to destination 16-bit Image in 16-bit container

Error creating thumbnail: Unable to save thumbnail to destination 15-bit image in 16-bit container

Example

//Using bit Conversion in C CuviMat* gimg,*gout; //Size of input and output should be same CuviSize size = cuviSize(img->width,img->height); cuviCreateMat(&gimg,size,img->depth,img->nChannels); cuviUploadData(gimg,img->imageData,img->widthStep); //Telling that input image has a depth of 7-bit gimg->dataBits = 7; cuviCreateMat(&gout,size,16,img->nChannels); //Convert 7-bit image into 15-bit image gout->dataBits = 15; cuviBitConversion(gimg,gout);
