Bounding boxes, specified as an M-by-4,
M-by-5, or M-by-9 nonsparse numeric matrix of
M bounding boxes. Each row, M, of the matrix
defines a bounding box as either an axis-aligned rectangle, a rotate rectangle, or a
cuboid. The table below describes the format of the bounding boxes.

Description

Axis-aligned rectangle

[x_{min},
y_{min}, width,
height]

This type of bounding box is defined in pixel coordinates as an
M-by-4 matrix representing M bounding
boxes

Rotated rectangle

[x_{center},
y_{center}, width,
height, yaw]

This type of bounding box is defined in spatial coordinates as an
M-by-5 matrix representing M bounding
boxes. The x_{center} and
y_{center} coordinates represent the
center of the bounding box. The width and
height elements represent the length of the box along the
x and y axes, respectively. The
yaw represents the rotation angle in degrees. The amount
of rotation about the center of the bounding box is measured in the clockwise
direction.

Defined in spatial coordinates as an M-by-9 matrix
representing M bounding boxes. The
x_{center},
y_{center}, and
y_{center} coordinates represent the
center of the bounding box. The width and
height elements represent the length of the box along
the x and y axes, respectively. The
rx,ry, and rz
rotation angles are in degrees about the cuboid center. The rotation is
positive in the clockwise direction, with respect to the positive direction of
the axis.

Rotation matrices are computed assuming ZYX
order Euler angles [rx, ry,
rz].

scale — Scale scalar (default) | row vector

Scale, specified as a scalar or a row vector. When you specify a scalar, the
function applies the same scale factor to the height and width of the bounding boxes in
bboxA. When you specify a row vector, the function applies the
factor in the first element of the vector to resize the height and the second element to
resize the width of the bounding boxes.

Warped bounding boxes, returned as an M2-by-N
matrix of M2 bounding boxes. The number of bounding boxes returned is
less than the number of bounding boxes in the input. Each row, M2, of
the matrix defines one bounding box of the same type as the input
bboxA.
