# SSD\_TO\_BBOX

`SSDToBoundingBoxStep` is a pipeline step that configures extraction of bounding boxes from a (Single-Shot Detector) SSD model output.

| --------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| classLabels     | A list of class labels                                                                                                                                                                                                                                                                                                                                                                                                                                                          |
| keepOtherValues | `true` by default. If `true`, other data key and values from the previous step are kept and passed on to the next step as well.                                                                                                                                                                                                                                                                                                                                                 |
| threshold       | Threadshold to the output of the SSD models for fetching bounding boxes for. Default threshold is `0.5`.                                                                                                                                                                                                                                                                                                                                                                        |
| scale           | An optional way to increase the size of the bounding boxes by some fraction. If specified, a value of `1.0` is equivalent to no scaling. A scale of `2.0` means the center is unchanged, but the width and height are now two times larger than it would be.                                                                                                                                                                                                                    |
| aspectRatio     | An optional way to control the output shape (aspect ratio) of the bounding boxes. Defined in terms of width or height. If specified, an aspect ratio of `1.0` gives a square output; an aspect ratio of `2.0` gives twice as wide as it is high. Note that for making the output the correct aspect ratio, one of the height or width will be increased; the other dimension will not change. The pre-aspect-ratio-corrected box will be contained fully within the output box. |
| outputName      | Output key name where the bounding box will be contained in. The default name is `bounding_box`.                                                                                                                                                                                                                                                                                                                                                                                |
