半色调技术对图像进行打印和显示。半色调技术是一种基于点模式的灰度级图像打印方案。在本实验中，给出了用点模式近似表示的10个灰度级-Halftone image printing and display. Half-tone technique is a model based on gray-scale image point of printing solutions. In this experiment, given the dot pattern similar to that of t

About correlation. In signal processing, cross-correlation is a measure of similarity of two waveforms as a function of a time-lag applied to one of them. This is also known as a sliding dot product or inner-product. It is commonly used to search a l
