Functions
DW_API_PUBLIC dwStatus	dwFeature2DDescriptor_bindBuffers (dwImageHandle_t image, const dwFeatureArray *features, dwFeature2DDescriptorHandle_t obj)
	Binds input parameters to descriptor object. More...
DW_API_PUBLIC dwStatus	dwFeature2DDescriptor_bindOutput (dwFeatureDescriptorArray *outputDescriptors, dwFeature2DDescriptorHandle_t obj)
	Binds output dwFeatureDescriptorArray to descriptor object. More...
DW_API_PUBLIC dwStatus	dwFeature2DDescriptor_getCUDAStream (cudaStream_t *stream, dwConstFeature2DDescriptorHandle_t obj)
	Gets the CUDA stream used by the feature descriptor. More...
DW_API_PUBLIC dwStatus	dwFeature2DDescriptor_getPVAStream (cupvaStream_t *stream, dwConstFeature2DDescriptorHandle_t obj)
	Gets the CUPVA stream used by the feature Descriptor. More...
DW_API_PUBLIC dwStatus	dwFeature2DDescriptor_initDefaultParams (dwFeature2DDescriptorConfig *params)
	Initializes dwFeature2DDescriptor parameters with default values. More...
DW_API_PUBLIC dwStatus	dwFeature2DDescriptor_initialize (dwFeature2DDescriptorHandle_t *obj, const dwFeature2DDescriptorConfig *config, cudaStream_t cudaStream, dwContextHandle_t context)
