我认为 StackBlur 是一个很棒的库，尤其是它能够按照你想要的方式模糊图像。我没有用过 GPUImage 库，但是同事说 StackBlur 比 GPUImage 慢。我在网上找不到任何信息。有人对此有见识吗？谢谢！

We were using GPUImage to apply blur effect to our images and decided to try stackblur to see if we can get better performance from it.
After the implementation, we first did simulator tests and stackblur did have better performance, especially with larger images. But when we tried it on actual devices the performance was much worse than GPUImage
