OpenCV
官网 https://opencv.org/ github地址https://github.com/opencv/opencv非常活跃的一个开源工具原来免费的教程现在已经开始包装成视频进行收费了我买了教程看了下和以前官网看过的文字版教程没多大差别。github关注已经达到了72.3k。
ImageJ
官网 https://imagej.net/ij/
ImageJ is open source software for processing and analyzing scientific images.
基于ImageJ已经又研发了ImageJ2目前github关注量1k和Fiji的产品。 // Open the TIFF image

JDeli 是一个付费软件
如下是测试结果
photoshop可以看到通道增加了专色通道。
