Method Detail

close

public void close()

Destroys the detector instance.

Specified by:

close in interface java.lang.AutoCloseable

See Also:

AiliaDetector.Destroy(long)

compute

public void compute(byte[] src,
                    int srcStride,
                    int srcWidth,
                    int srcHeight,
                    AiliaImageFormat srcFormat,
                    float threshold,
                    float iou)
             throws AiliaException

Performs object detection.

Parameters:

src - Image data (32 bpp)

srcStride - The number of bytes in 1 line

srcWidth - Image width

srcHeight - Image height

srcFormat - Image format (AiliaImageFormat)

threshold - The detection threshold (for example, 0.1f) (The smaller it is, the easier the detection will be and the more detected objects found.)

iou - Iou threshold (for example, 0.45f) (The smaller it is, the fewer detected objects found, as duplication is not allowed.)

Throws:

AiliaException - Exception

See Also:

AiliaDetector.Compute(long, byte[], int, int, int, int, float, float)

getObjectCount

public int getObjectCount()
                   throws AiliaException

Gets the number of detection results.

Returns:

The number of objects

Throws:

AiliaException - Exception

See Also:

AiliaDetector.GetObjectCount(long)

getObject

public AiliaDetectorObject getObject(int index)
                              throws AiliaException

Gets the detection results.

Parameters:

index - Object index

Returns:

Object information

Throws:

AiliaException - Exception

See Also:

AiliaDetector.GetObject(long, int, int)

setAnchors

public void setAnchors(float[] anchors)
                throws AiliaException

Sets the anchor information (anchors or biases) for YoloV2 or other systems.

Parameters:

anchors - The anchor dimensions (the shape, height and width of the detection box)

Throws:

AiliaException - Exception
