Implementations§
source§impl CUDA_CascadeClassifier
impl CUDA_CascadeClassifier
sourcepub fn create(filename: &str) -> Result<Ptr<CUDA_CascadeClassifier>>
pub fn create(filename: &str) -> Result<Ptr<CUDA_CascadeClassifier>>
Loads the classifier from a file. Cascade type is detected automatically by constructor parameter.
§Parameters
- filename: Name of the file from which the classifier is loaded. Only the old haar classifier (trained by the haar training application) and NVIDIA’s nvbin are supported for HAAR and only new type of OpenCV XML cascade supported for LBP. The working haar models can be found at opencv_folder/data/haarcascades_cuda/
sourcepub fn create_1(
file: &impl FileStorageTraitConst
) -> Result<Ptr<CUDA_CascadeClassifier>>
pub fn create_1( file: &impl FileStorageTraitConst ) -> Result<Ptr<CUDA_CascadeClassifier>>
Loads the classifier from a file. Cascade type is detected automatically by constructor parameter.
§Parameters
- filename: Name of the file from which the classifier is loaded. Only the old haar classifier (trained by the haar training application) and NVIDIA’s nvbin are supported for HAAR and only new type of OpenCV XML cascade supported for LBP.

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
