Thus, it's possible to improve CSF without changing basic aspects of vision by training the brain in a way that heightens awareness of contrast.

因此，在不改变基本视力的前提下，通过某种提高对比度知觉的方式训练大脑有可能改善CSF。

For understandable reasons, teachers rarely get much training in their own classrooms (in contrast, doctors do a lot of training in hospital wards).

基于一些很容易理解的原因，老师在教室里没什么练习的机会(医生却不同，他们可以做实习医院做大量的练习)。

Contrast to the stack filter based edge detection. the proposed method gainis higher speed, uses less memory for optimal training of stack filter.

相对于基于堆栈滤波器边界检测法，该方法对堆栈滤波器的优化训练速度大大提高，所需内存大为减少；
