hi,

Last test with all optimization. Xiaomi 13T PRO is 3 to 5 time faster than hauwei.

remove all the .wait and .flush at the end of the JNI function where you are doing your OpenCL kernel and CPU processing.

hi, Last test after using 64bit on hauwei mali G72 mp12. Using 64bit increase the performance and i can get 25% more than  xiaomi 13T pro mp11. Anaway booth of them start doing wrong over 100 ms for image processing. I just test it today i wanted to be sure about what i said before. So using 64bit in OpenCL is a lot much better. ;))

But xiaomi is slower but stable in time. Hauwei can goes from 100% to 400% time consuming during some time and then going back to 100%. I think it is comming from the focus of the camera, or memory GPU cleaning. I am not sure yet. I will let you know. ;))

In fact the diferrence come from the camera. I got more data with the Xiaomi, more détail. So more data to process and more time consuming. So let said xiaomi is more accurate.
