easycv.core.visualization package¶
- easycv.core.visualization.imshow_bboxes(img, bboxes, labels=None, colors='green', text_color='white', font_size=20, thickness=1, font_scale=0.5, show=True, win_name='', wait_time=0, out_file=None)[source]¶
Draw bboxes with labels (optional) on an image. This is a wrapper of mmcv.imshow_bboxes.
- Parameters
img (str or ndarray) – The image to be displayed.
bboxes (ndarray) – ndarray of shape (k, 4), each row is a bbox in format [x1, y1, x2, y2].
labels (str or list[str], optional) – labels of each bbox.
colors (list[str or tuple or
Color]) – A list of colors.text_color (str or tuple or
Color) – Color of texts.font_size (int) – Size of font.
thickness (int) – Thickness of lines.
font_scale (float) – Font scales of texts.
show (bool) – Whether to show the image.
win_name (str) – The window name.
wait_time (int) – Value of waitKey param.
out_file (str, optional) – The filename to write the image.
- Returns
The image with bboxes drawn on it.
- Return type
ndarray
- easycv.core.visualization.imshow_keypoints(img, pose_result, skeleton=None, kpt_score_thr=0.3, pose_kpt_color=None, pose_link_color=None, radius=4, thickness=1, show_keypoint_weight=False)[source]¶
Draw keypoints and links on an image.
- Parameters
img (str or Tensor) – The image to draw poses on. If an image array is given, id will be modified in-place.
pose_result (list[kpts]) – The poses to draw. Each element kpts is a set of K keypoints as an Kx3 numpy.ndarray, where each keypoint is represented as x, y, score.
kpt_score_thr (float, optional) – Minimum score of keypoints to be shown. Default: 0.3.
pose_kpt_color (np.array[Nx3]`) – Color of N keypoints. If None, the keypoint will not be drawn.
pose_link_color (np.array[Mx3]) – Color of M links. If None, the links will not be drawn.
thickness (int) – Thickness of lines.
- easycv.core.visualization.imshow_label(img, labels, text_color='blue', font_size=20, thickness=1, font_scale=0.5, intervel=5, show=True, win_name='', wait_time=0, out_file=None)[source]¶
Draw images with labels on an image.
- Parameters
img (str or ndarray) – The image to be displayed.
labels (str or list[str]) – labels of each image.
text_color (str or tuple or
Color) – Color of texts.font_size (int) – Size of font.
thickness (int) – Thickness of lines.
font_scale (float) – Font scales of texts.
intervel（int) – interval pixels between multiple labels
show (bool) – Whether to show the image.
win_name (str) – The window name.
wait_time (int) – Value of waitKey param.
out_file (str, optional) – The filename to write the image.
- Returns
The image with bboxes drawn on it.
- Return type
ndarray
