The processing parameters, which are regulated real-time to get better result, include window function, filter parameters and so on.

窗函数、滤波器参数等都可以调整，以得到较好的信号处理结果。

Optical joint transform correlation can recognize automatically, overcome the drawback of filter-based correlator, and it is suitable for real-time processing, can achieve better recognition result.

克服了经典的匹配滤波相关存在大的相关旁瓣、很大的相关带宽和低的光效率等缺点。

Some photographers have thrown every filter and post-processing technique at a photo and called the result art.
