Constant Field Values

x

public int x

x-coordinator of the point on the left-upper corner of the bounding box.

y

public int y

y-coordinator of the point on the left-upper corner of the bounding box.

width

public int width

The width of the bounding box.

height

public int height

The height of the bounding box.

patchData

public byte[] patchData

The RGB data of the patch croped by the bounding box. If not available, it should be set to null. Otherwise, it should follow the format of the 'data' field of OpenCV 2.x's Mat class. When reconstructing a OpenCV's Mat with this bounding box, first allocate a Mat with width and height same to this bounding box and format as CV_8UC3, then directly copy data of the 'patchData' field here to the 'data' field of it using functions like memcpy.

BoundingBox

public BoundingBox()

Method Detail

toString

public String toString()

Transform the bounding box to a Json string. The string contains location information only (no pixel data).

Overrides:

toString in class Object

Returns:

A Json string representing the location information of the bounding box.

toBytes

public byte[] toBytes()

Transform the bounding box into a byte array.

Returns:

16 bytes representing x, y, width and height, then width * height * 3 bytes representing the pixels in the patch.

getImage

public org.bytedeco.javacpp.opencv_core.Mat getImage()

Get the image stored in the bounding box.

Returns:

a OpenCV Mat (by Bytedeco) with CV_8SC3 data form.
