Iplimage Vs Mat

Iplimage vs 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. So the data layout in mat is fully compatible with cvmat iplimage and cvmatnd types from opencv 1 x. Cv mat is the new type introduce in opencv2 x while the iplimage is the legacy image structure. You will need to extract the image header information manually.

You will need to extract the image header information manually. Do remember that you need to allocate the iplimage. For some reason cv mat s leak on mac whereas iplimage s don t x dec 9 12 at 15 48. Do remember that you need to allocate the iplimage structure which is lack in.

Thanks for this article. Cv mat is the new type introduce in opencv2 x while the iplimage is the legacy image structure. I felt like i could better reuse my memory allocations. Iplimage support roi region of interest and coi color of interest.

When i started to experiment with the deprecated iplimage instead of cv mat some functionalities were surprisingly well written there and i had more firm control over the memory. Dst img cvgetimage src mat stub. Note that if we transform iplimage to cvmat and then transform cvmat back to iplimage we can get different headers if the roi is set and thus some ipl functions that calculate image stride from its width and align may fail on the resultant image.
