混沌的判断指标Lyapunov指数计算,数据模型归一化，模态振动，多目标跟踪的粒子滤波器。( Chaos indicator for Lyapunov index calculation, Normalized data model, modal vibration, Multi-target tracking particle filter.)

This code applies global histogram equalization on an input image with a view to improve its contrast ratio. The image is read, converted to grayscale and resized with the inbuilt function of MATLAB. The output is definitely a better contrast image as compared to the input
