经典HOG算法，基于梯度的直方图提取算法，用于人体检测十分有效！,HOG classic algorithms, gradient-based histogram extraction algorithms, used in human testing is very effective!

显微镜自动对焦MFC+opencv，包括数据采集和聚焦评价函数算法，后面继续奉上步进电机控制-Microscope autofocus MFC+opencv, including data collection and focusing evaluation function algorithm, the latter continue to offer the stepper motor control
