Abstract

一种图像处理方法和装置，其中，该图像处理方法包括：根据输入图像检测区域的清晰度计算背景模型的灵敏度，该清晰度在第一预定范围内时，该灵敏度和该清晰度负相关；对该输入图像中的每个像素进行处理，其中，在对一个像素进行处理时，包括：计算该一个像素与在该背景模型中对应该一个像素的背景样本集中的每个样本点之间的距离，在该一个像素与至少第一预定数量个样本点的距离小于等于预定的第一阈值时，将该一个像素确定为该输入图像中的背景像素；该第一阈值根据该灵敏度确定，该灵敏度与该第一阈值负线性相关。上述实施例中的装置为VIBE算法中的背景模型定义灵敏度，并根据图像的清晰度来调整该灵敏度，由此，能够提高前景检测的准确度，避免图像变的模糊而无法提取完整的前景图像的问题。
