java中的开源图像倾斜检测/校正库？
我需要对某些图像执行倾斜校正（假设格式是 tiff）。也就是说，我有一些图像可能会向右或向左倾斜，我需要调整它们，使它们垂直向上和向下。图像由文字和线条组成；这些线条基本上是文本周围的边框；所以所有的线都是水平和垂直的（这有望简化问题）。
有没有一个开源的java库可以帮助解决这个问题？
I need to perform skew correction on some images (lets say the format is tiff). That is, I have some images which can come in tilted to the right or left and I need to adjust them so that they are straight up and down. The images consist of text and lines; the lines are basically borders around the text; so all of the lines are horizontal and vertical (which hopefully simplifies the problem).
Is there an open source java library that would help with this?
