This is my srcImage
When I use this code
Mat srcImage = imread("1.jpg", 0),test;
dstImage.create(srcImage.size(),srcImage.type());
I will ge such dstImage
Note the place pointed by yellow arrow. I get so many white noise. It is a intention or a bug of OpenCV?
Create simply allocates memory to hold an image in the size and shape requested. It guarantees nothing about the contents of the memory.
You can either use the constructor with a default value, or the setTo function after the create to set the contents.
See the documentation HERE. Note the absence of a step that sets the values. Also note that if it matches the size and shape already, it returns immediately, leaving the existing data intact.
