# BNNSFilterParameters

A structure that contains common filter parameters.

```
struct BNNSFilterParameters
```

## Topics

### Initializers

[`init(options:threadCount:allocator:deallocator:)`](/documentation/Accelerate/BNNSFilterParameters/init(options:threadCount:allocator:deallocator:))

Returns a new common filter parameters structure using the specified options.

[`init(flags:n_threads:alloc_memory:free_memory:)`](/documentation/Accelerate/BNNSFilterParameters/init(flags:n_threads:alloc_memory:free_memory:))

Returns a new common filter parameters structure.
