Member Function Documentation

◆ ailiaCreateDetector()

static int ailia.AiliaDetector.ailiaCreateDetector ( ref IntPtr  detector,
IntPtr  net,
UInt32  format,
UInt32  channel,
UInt32  range,
UInt32  algorithm,
UInt32  category_count,
UInt32  flags 
)

◆ ailiaDestroyDetector()

static void ailia.AiliaDetector.ailiaDestroyDetector ( IntPtr  detector)

Destroy the detector object.

Parameters
detectorDetection object pointer

◆ ailiaDetectorCompute()

static int ailia.AiliaDetector.ailiaDetectorCompute ( IntPtr  detector,
IntPtr  src,
UInt32  src_stride,
UInt32  src_width,
UInt32  src_height,
UInt32  src_format,
float  threshold,
float  iou 
)

Perform object recognition.

Parameters
detectorDetection object pointer
srcImage data (32bpp)
src_strideByte count of one line
src_widthImage width
src_heightImage height
src_formatImage format (AILIA_IMAGE_FORMAT_*)
thresholdDetection threshold (e.g. 0.1f) (the smaller the threshold, the more likely it is to be detected and the more detections will be made)
iouDuplicate exclusion threshold (e.g. 0.45f) (the smaller the threshold is, the less duplicates are allowed and the fewer the number of detections)
Returns
If successful, return AILIA_STATUS_SUCCESS, otherwise return error code.

◆ ailiaDetectorGetObject()

static int ailia.AiliaDetector.ailiaDetectorGetObject ( IntPtr  detector,
[In, Out] AILIADetectorObject  obj,
UInt32  obj_idx,
UInt32  version 
)

Get the recognition result.

Parameters
detectorDetection object pointer
objobject information
obj_idxobject index
versionAILIA_DETECTOR_OBJECT_VERSION
Returns
Returns AILIA_STATUS_SUCCESS if successful, otherwise returns error code.

If ailiaPredict() has never been executed, then return * AILIA_STATUS_INVALID_STATE. Recognition results are sorted in order of probability.

◆ ailiaDetectorGetObjectCount()

static int ailia.AiliaDetector.ailiaDetectorGetObjectCount ( IntPtr  detector,
ref UInt32  obj_count 
)

Get the number of recognition results.

Parameters
detectorDetection object pointer
obj_countNumber of objects
Returns
If successful, return AILIA_STATUS_SUCCESS, otherwise return error code.

◆ ailiaDetectorSetAnchors()

static int ailia.AiliaDetector.ailiaDetectorSetAnchors ( IntPtr  detector,
float[]  anchors,
UInt32  anchors_count 
)

Set anchors or biases information for YoloV2 etc.

Parameters
detectorDetection object pointer
anchorsDimensions of anchors (possible shape, height and width of detection box)
anchors_countnumber of anchors (half of the array size of anchors)
Returns
Return AILIA_STATUS_SUCCESS if successful, otherwise return error code.

YoloV2, for example, tries multiple forms of the default detection box at the same time. This data describes the plural form of the box. anchors is stored in the form {x,y,x,y...} The anchors are stored in the form {x,y,x,y...}. If anchors_count is 5, then anchors is a 10-dimensional array.

◆ ailiaDetectorSetInputShape()

static int ailia.AiliaDetector.ailiaDetectorSetInputShape ( IntPtr  detector,
UInt32  input_width,
UInt32  input_height 
)

Specifies the input image size to the model in YoloV3.

Parameters
detectorDetection object pointer
input_widthInput image width for the model
input_heightInput image height of the model
Returns
Returns AILIA_STATUS_SUCCESS if successful, otherwise returns an error code.

YoloV3 allows a single model to correspond to any input resolution. (with a multiple limit of 32) Execute this API if you want to specify the input image size for a model, e.g. to reduce computation time. This API must be executed between ailiaCreateDetector() and ailiaDetectorCompute(). If this API is not executed, the default value of 416x416 is used. If executed outside of YOLOv3, it returns AILIA_STATUS_INVALID_STATE.
