由于需要将部分128×128数据扩大到720×720使用 测试了下cv2.resize()函数不同插值方法的结果 new_img = cv2.resize(img, (720, 720), interpolation=cv2.INTER_NEAREST) interpolation - 插值方法。共有5种: 1)INTER_NEAREST - 最近邻插值法 2)INTER_......

cv2.resize(source, dim, fx, fy, interpolation) Parameters You can pass 5 parameters to resize() method. Among the 5 parameters, the first two(source and dim) are mandatory; rest(fx, fy and interpolation) are optional. source: Source/Original/Input image i.e that image n-dimensional array...
在做图像数据增强的时候,经常会出现shape错乱的问题而出现很多bug。比较好的做法是,比如resize rotate 这些的函数,统一都使用cv2的,感觉它处理图像还是靠谱的。之前用过transform的rotate resize之类的 就比较混乱。。。 给个cv2做rotate的栗子:...图像的增强之空域增强 图像的增强之空域增强...图像...
