mmocr.utils.crop_img

mmocr.utils.crop_img(src_img, box, long_edge_pad_ratio=0.4, short_edge_pad_ratio=0.2)

Crop text region given the bounding box which might be slightly padded. The bounding box is assumed to be a quadrangle and tightly bound the text region.

参数

• src_img (np.array) – The original image.

• box (list[float | int]) – Points of quadrangle.

• long_edge_pad_ratio (float) – The ratio of padding to the long edge. The padding will be the length of the short edge * long_edge_pad_ratio. Defaults to 0.4.

• short_edge_pad_ratio (float) – The ratio of padding to the short edge. The padding will be the length of the long edge * short_edge_pad_ratio. Defaults to 0.2.
