-
cvtools.utils.image.draw_boxes_texts(img, boxes, texts=None, colors=None, line_width=1, draw_start=False, box_format='x1y1x2y2')[源代码]¶ Draw bboxes on an image.
参数: - img (str or ndarray) -- The image to be displayed.
- boxes (list or ndarray) -- A list of ndarray of shape (k, 4).
- texts (list) -- A list of shape (k).
- colors (list[tuple or Color]) -- A list of colors.
- line_width (int) -- Thickness of lines.
- draw_start (bool) -- Draw a dot at the first vertex of the box.
- box_format (str) -- x1y1x2y2(default), x1y1wh, xywh, xywha, polygon
-
cvtools.utils.image.draw_class_distribution(y, save_name='class_distribution.png')[源代码]¶ 绘制饼图,其中y是标签列表
-
cvtools.utils.image.draw_hist(data, bins=10, x_label='区间', y_label='频数/频率', title='频数/频率分布直方图', show=True, save_name='hist.png', density=True)[源代码]¶ 绘制直方图 data: 必选参数，绘图数据 bins: 直方图的长条形数目，可选项，默认为10
-
cvtools.utils.image.imread(img_or_path, flag='color')[源代码]¶ Read an image.
参数: - img_or_path (ndarray or str) -- Either a numpy array or image path. If it is a numpy array (loaded image), then it will be returned as is.
