Hi,

I am trying to display a grayscale image in a visual studio C++ picture box. I followed the code below yet it says the mixChannels argument are not correct. What is &amp ?

Mat gray_3channels(gray.rows, gray.cols, CV_8UC3);
 Mat in[] = { gray, gray, gray };
 int from_to[] = { 0,0, 1,1, 2,2 };
 mixChannels( in, 3, &amp;gray_3channels, 1, from_to, 3 );

But if anyone knows how else i can easily display grayscale image in a picture box please do tell me. Thanks

&amp = & (different encoding/escape format)

You achieved the &amp by copy pasting from a webpage. Simply replace the & part with a & and your code will work perfectly fine...

The reason why the & is actually there is to ensure that your are writing to the correct shared data instance, instead of just passing the pointer around!
