基于matlab的火焰高度求解，主要使用的是分布概率法，实验将视频中的火焰按帧取出1512张火焰图进行火焰分析，涉及到灰度图、二值化以及其他MATLAB函数应用。简洁明了，适合学习，且具有一定的工程意义。(This is a program solving the height of falme which based on matlab,mainly used the distributing probabilty.The experiment is analysed by 1512 flame picture which producded by a 3 minute video.The analysis is concerned with Gray,THresholding and other matlab function.The program is simple but important to engineering!)
