示例1: write_images
# 需要导入模块: from SimpleCV.ImageClass import Image [as 别名]
# 或者: from SimpleCV.ImageClass.Image import crop [as 别名]

if options.crop:
# although FGVC pages says the orgin is (1,1)
# still there's some coordinates in box have 0 value
# so don't do adjustment - 1px difference should be OK
