} | S )aô Extract image patch from bounding box.
|
|
Parameters
|
----------
|
image : ndarray
|
The full image.
|
bbox : array_like
|
The bounding box in format (x, y, width, height).
|
patch_shape : Optional[array_like]
|
This parameter can be used to enforce a desired patch shape
|
(height, width). First, the `bbox` is adapted to the aspect ratio
|
of the patch shape, then it is clipped at the image boundaries.
|
If None, the shape is computed from :arg:`bbox`.
|
|
Returns
|
-------
|
ndarray | NoneType
|
An image patch showing the :arg:`bbox`, optionally reshaped to
|
:arg:`patch_shape`.
|
Returns None if the bounding box is empty or fully outside of the image
|
boundaries.

|
|
Parameters
|
----------
|
encoder : Callable[image, ndarray] -> ndarray
|
The encoder function takes as input a BGR color image and a matrix of
|
bounding boxes in format `(x, y, w, h)` and returns a matrix of
|
corresponding feature vectors.
|
mot_dir : str
|
Path to the MOTChallenge directory (can be either train or test).
|
output_dir
|
Path to the output directory. Will be created if it does not exist.
|
detection_dir
|
Path to custom detections. The directory structure should be the default
|
MOTChallenge structure: `[sequence]/det/det.txt`. If None, uses the
|
standard MOTChallenge detections.
