Dear Daniel, could you tell me how to set the image data (unsigned char *) is stored as a Mat of Ope-CodePudding

Existing image data width, height, Imagedata, nChannels, Daniel, help!

CodePudding user response:

Mat YouImg (height, width, CV_8UC3, ImageData),
Or a for loop assignment

CodePudding user response:

Direct copy

 
Unsined char YourData (1024 * 800), 
Mat yourMat (800102 4, CV_8UC1); 
Memcpy (yourMat  the data , YourData, 1024 * 800 * (unsined char));

CodePudding user response:

refer to the second floor u012947309 response:

direct copy

 
Unsined char YourData (1024 * 800), 
Mat yourMat (800102 4, CV_8UC1); 
Memcpy (yourMat  the data , YourData, 1024 * 800 * (unsined char));

The original can't add certain parts of the code color
The last sentence is so

 memcpy (yourMat. Data, YourData, 1024 * 800 * (unsined char));

CodePudding user response:

Mat yourMat (800102 4, CV_8UC1); Why is CV_8UC1?

CodePudding user response:

Direct copy for gray image save out there was a problem
