【摘要】 通过C328摄像头模块采集160×128的低分辨率JPEG图像,解码之后采用改进的背景差法进行运动检测分离出运动目标区域,利用块的空间相关性与形状学结合的方法去除噪声,并在运动目标区域超过设定阈值时抓拍高分辨率图像。实验证明,在采集的图像噪声较高的情况下,此方法简单、快速而有效,并可应用到嵌入式系统中。更多还原

【Abstract】 Using C328 Monitor Module to capture JPEG image with low resolution of 160×128,when finish decoding the image,separate the motion area by the way of improved background subtraction,for wiping off the noise,the method of space relativity of blocks and morphology are employed,at last,if the motion area is more than the threshold which is set,the system will get a snapshot image with high resolution.The experiments show that this method is simple,rapid and efficient,at the same time,is applied to embedded system.更多还原
