WebOpenCV was designed for computational efficiency and with a strong focus on real-time applications. Written in optimized C/C++, the library can take advantage of multi-core … WebDESCRIPTION ¶. The float (or double if optional double is supported) value given by data is first converted to a half value using the appropriate rounding mode. The half value is then written to address computed as ( p + offset ). The address computed as ( p + offset) must be 16-bit aligned. vstore_half uses the current rounding mode.
