Struct arrayfire::Features

pub struct Features { /* fields omitted */ }

A set of Array objects (usually, used in Computer vision context)

Features struct is used by computer vision functions to return the outcome of their operation. Typically, such output has the following Arrays:

• X positions of the features
• Y positions of the features
• Scores of the features
• Orientations of the features
• Sizes of the features

Sharing Across Threads

While sharing this object with other threads, there is no need to wrap this in an Arc object unless only one such object is required to exist. The reason being that ArrayFire's internal details that are pointed to by the features handle are appropriately reference counted in thread safe manner. However, if these features are to be edited, then please do wrap the object using a Mutex or Read-Write lock.

Implementations
