Python crop_around_centroid Examples

Example #1

    org_region = di.get_largest_region(x)
    rr1, cc1   = di.get_bbox_center(org_region.bbox)

    _x         = cc1 - x.shape[1]/2
    _y         = rr1 - x.shape[0]/2
    cc2, rr2   = di.point_rotate(_x, _y, -org_region.orientation)
    rr2       += rotated_x.shape[0]/2
    cc2       += rotated_x.shape[1]/2
    cropped    = di.crop_around_centroid(rotated_x, rr2, cc2)
    return cropped

Example #2
