基于局部直方图的目标分割方法

图像分割是图像精确跟踪中的重要组成部分 ,是后续进行图像识别的基础。在介绍传统阈值分割方法的基础上 ,提出了一种应用序列图像跟踪、利用跟踪区域的局部直方图来计算分割阈值的方法。该方法利用相邻两帧图像数据的相关性 ,根据跟踪区域的灰度信息自动调节每帧图像的分割阈值 ,使在跟踪区域内的目标得到了较好的分割效果。运用该算法 ,不仅取得了良好的分割效果 ,而且结果证明该算法具有较强的自适应性

Method of target division based on part histogram

Image segmentation is an important part of image tracing, and it is also the bas e of the image recognition. Based on introducing traditional method of th reshold segmentation, an effective segmentation algorithm is provided, the se gmentation threshold is adjusted automatically for differen t frames after considering the relativity between two sequential frames. In orde r to get real time tracing, only the gray information of the trace region is co nsidered. At last the algorithm is used in a serial images, and not only good effect of segmentation is gotten, but also the result proves that algorithm is a uto adapt.
