Financial Econometrics MFE MATLAB Notes:These notes provide an introduction to MATLAB with an emphasis on the tools most useful in econometrics and statistics. All topics relevant to the MFE curriculum should be covered but if any relevant topic is missing or under-explained, please let me know and I’ll add examples as necessary.

Color can provide an efficient visual feature for tracking nonrigid objects in real-time. However, the color of an object can vary over time dependent on the illumination, the visual angle and the camera parameters. To handle these appearance changes a color-based target model must be adapted during temporally stable image observations. This paper presents the integration of color distributions into particle filtering and shows how these distributions can be adapted over time. A particle filter tracks several hypotheses simultaneously and weights them according to their similarity to the target model. As similarity measure between two color distributions the popular Bhattacharyya coefficient is applied. In order to update the target model to slowly varying image conditions, frames where the object is occluded or too noisy must be discarded.

该功能实现了颜色均衡化，使得视觉更加的良好(the function acommplish the color balance so that make a good looking of landscape)

说明：  在现代信号处理领域非常重要的方法。这是最新的改进算法！(in modern signal processing field is very important way. This is the latest improved algorithm!)

----------------------------------------------------- This file produces the output file test_impulse.wav containing an approximation to the unit impulse (delta) function. The value of alpha on [0,1] determines the bandlimit of the approximation. This method is used to avoid the technical difficulties in producing (and reproducing) an ideal impulse (delta) function in audio. This file also produces the .wav audio file test_audio.wav which is an audio test vector intended to be used in the impulse response inversion experiment. (4/24/2002) NOTE: Impulse is bandlimited to alpha*Fmax where Fmax = Fs/2, or the Nyquist frequency.
