I have a problem with passing Mat (opencv4android) array between two android activities,anyone can help me?
I have solved this problem by writing Mat array to SD-Card as images and read images from SD-Card in another activity.but it has a problem with speed when running on the android phone.
thanks.
How about getting native address of a Mat (getNativeObjAddr), and passing the address to another activity in intent extras. Then just create new Mat array with this address?
