c# - Opencv: Working with 16bit image, Uint16 -

i have 12bit image want work in opencv, such detecting blobs etc.

the image uint16 array. , want convert opencv mat or iplimage. need inorder threshold , detect blobs.

what im doing convert ushort array bitmap, , mat using opencv extensions, see below.

ushort[,] red = new ushort  [480,640]; //grab image in ushort array //..  bmpred = u16arraytobitmap(red);  mat redmat = new mat();  redmat = opencvsharp.extensions.bitmapconverter.tomat(bmpred); 

now redmat, mat image u8c4, understand 4 chanel unsigned 8 bit. wont work me, because want use of 12 bits!

is possible convert ushort array or bitmap 16bit grayscale mat or iplimage?

thanks!

you can use mat constructor directly:

var mat = new mat(red.getlength(0), red.getlength(1), mattype.cv_16uc1, red); 

or use matofushort:

var mat = new matofushort(red.getlength(0), red.getlength(1), red); 

note mat using pointer red array. clone mat if want use copy:

var clone = mat.clone(); 

for more information check mat - basic image container opencv documentation page , opencvsharp wiki.
