@ww23 添加中文的文字水印，有什么方案嘛？

ww23 commented 6 years ago

@aaronwong1989 OpenCV 不支持 non-ACSII，你可以尝试使用 Java 2D。

ww23 commented 6 years ago

已修复。DFT 要抗 JPG 或者 JPEG 压缩需要加强水印强度，这样出来的图片效果不好。还有另一种方法是换成 DCT （这个我有打算做）。

aaronwong1989 commented 6 years ago

@ww23 神了，确实好使了，但是代码只是条了下“格式”而已啊，就是显式的定义了一下变量而已怎么就好了。。。

ww23 commented 6 years ago

@aaronwong1989 这样做可以保证 channel 一样，我换了种写法，应该比较好理解。

见 4fbd970088a3c1428c7f924b948c499301c04d49 ，要保证图片在同一个 channels。
