Unless there is a memory leak, the memory should be reclaimed when starting a new scan. However if on iOS it is like on unix system, the RAM may appear not released though it is. For example, if the second scan is smaller than the first one, the memory usage may remain at 1000 after mapping.

Thank You for the reply.
I tried to run the application in Xcode Instruments, and when I pop the scan view controller from the navigation stack I have 9 memory leaks. This is the leaks output, don't know if can be of any help

Total of bytes is around 1.5MB. Most of these functions are called only once, so maybe not the source of the huge memory usage you are seeing. A cv::Ptr is a smart pointer, not sure it shows up as a "leak".
