|
|
Destructor for SCascade.

softcascade::SCascade::load
|
||
|
|
--------------------------
|
||
|
|
Load cascade from FileNode.
|
||
|
|
|
||
|
|
.. ocv:function:: bool gpu::SCascade::load(const FileNode& fn)
|
||
|
|
|
||

|
:param fn: File node from which the soft cascade are read.

|
|
||
|
|
|
||
|
|
softcascade::SCascade::detect
|
||
|
|
--------------------------
|
||
|
|
Apply cascade to an input frame and return the vector of Decection objcts.
|
||
|
|
|
||
|
|
.. ocv:function:: void gpu::SCascade::detect(InputArray image, InputArray rois, OutputArray objects, Stream& stream = Stream::Null()) const
|
||
|
|
|
||
|
|
:param image: a frame on which detector will be applied.
|
||
|
|
|
||
|
|
:param rois: a regions of interests mask generated by genRoi. Only the objects that fall into one of the regions will be returned.
|
||
|
|
|
||
|
|
:param objects: an output array of Detections represented as GpuMat of detections (SCascade::Detection). The first element of the matrix is actually a count of detections.
|
||
|
|
|
||
|
|
:param stream: a high-level CUDA stream abstraction used for asynchronous execution.
