pub struct BIF { /* private fields */ }
Expand description
Implementation of bio-inspired features (BIF) from the paper: Guo, Guodong, et al. “Human age estimation using bio-inspired features.” Computer Vision and Pattern Recognition, 2009. CVPR 2009.
Implementations§
source§impl BIF
impl BIF
sourcepub fn create_def() -> Result<Ptr<BIF>>
pub fn create_def() -> Result<Ptr<BIF>>
§Parameters
- num_bands: The number of filter bands (<=8) used for computing BIF.
- num_rotations: The number of image rotations for computing BIF.
§Returns
Object for computing BIF.
§Note
This alternative version of BIF::create function uses the following default values for its arguments:
- num_bands: 8
- num_rotations: 12

source§fn empty(&self) -> Result<bool>
fn empty(&self) -> Result<bool>
Returns true if the Algorithm is empty (e.g. in the very beginning or after unsuccessful read
source§fn save(&self, filename: &str) -> Result<()>
fn save(&self, filename: &str) -> Result<()>
Saves the algorithm to a file.
In order to make this method work, the derived class must implement Algorithm::write(FileStorage& fs).
source§fn get_default_name(&self) -> Result<String>
fn get_default_name(&self) -> Result<String>
Returns the algorithm string identifier.
This string is used as top level xml/yml node tag when the object is saved to a file or string.

unsafe fn modify_inplace<Res>( &mut self, f: impl FnOnce(&Mat, &mut Mat) -> Res ) -> Res
Helper function to call OpenCV functions that allow in-place modification of a
Mat
or another similar object. By passing
a mutable reference to the Mat
to this function your closure will get called with the read reference and a write references
to the same Mat
. This is of course unsafe as it breaks the Rust aliasing rules, but it might be useful for some performance
sensitive operations. One example of an OpenCV function that allows such in-place modification is imgproc::threshold
. Read more
