Qimage img uchar mat data mat cols mat rows qimage format rgb32. Cv mat is the new type introduce in opencv2 x while the iplimage is the legacy image structure. It is more efficient than manually converting the pixels to the qimage but you have to keep the original cv mat image in memory. You will need to extract the image header information manually.

To convert from cv mat to qimage you could try to use the qimage uchar data int width int height format format constructor as follows mat is a cv mat. Although cv mat does support the usage of iplimage in the constructor parameters the default library does not provide function for the other way. You have cv mat old iplimage copy old. Iplimage ipl.

Do remember that you need to allocate the iplimage structure which is lack. So when you do a regular copy such as. Cv mat a b. It holds the number of cv mat headers currently pointing to that data pointer.

Cv mat m cv cvarrtomat ipl. Taking a look at core src matrix cpp it seems that indeed the constructor cv mat iplimage has disappeared. So mat dims is always 2 can also be 0 when the array is empty. Iplimage new image copy.

A will point to b s data and the reference count for it will be incremented.

Thanks for this article.

All the other ways are too complicated and this is the best one. Cv mat is a header that points to a data pointer which holds the actual image data. It passes the number of dimensions 1 to the mat constructor but the created array will be 2 dimensional with the number of columns set to 1. Use a copy constructor or assignment operator where there can be an array or expression on the right side see below.
