@asmorkalov, CV_FP16 is quite important feature and will be even more important in the new dnn and imgproc modules. If I understand correctly, we correctly detect ARM Neon on Windows. CV_FP16 (unlike CV_NEON_FP16) is a subset of CV_NEON. Therefore, on Windows@ARM systems we need to change the check for CV_FP16 with the check for CV_FP16+CV_NEON. |

The issue is that most of branches with f16 on Windows are implemented for x86. We need to revise all of them and fix. The idea of the patch -disable fp16 for now to unblock default configuration build. You are welcome to fix fp16 for ARM Windows. |
