)Rectangles on an input image.
~input/class
(jsk_recognition_msgs/ClassificationResult
)Class labels for each rectangles.
Publishing Topic¶
~output
(sensor_msgs/Image
)Image on which rectangles and classes are drawn.
Parameters¶
~approximate_sync
(Bool, default:False
)Whether to use approximate for input topics.
~queue_size
(Int, default:100
)How many messages you allow about the subscriber to keep in the queue. This should be big when there is much difference about delay between two topics.
~use_classification_result
(Bool, default:False
)Use
~input/class
as class labels if enabled.~show_proba
(Bool, default:True
)Show probability for each class labels if enabled. This option is valid when
~use_classification_result
isTrue
.~rect_boldness
(Int, default:2

~label_size
(Double, default:1.0
)Text size for each class labels.
~label_boldness
(Double, default:2.0

1.0
, an output image has the same resolution as an input image.~interpolation_method
(Enum[Int], default:INTER_LANCZOS4
