报童问题(负指数分布) 几个参数： 卖出报纸挣a元，退回报纸赔b元 卖报量y,订报量z，订报量上限z_up 观察期的总天数t,用于积累天数的ti 总的平均损失量ave_loss，供过于求损失loss1,供小于求损失loss2,ave_loss=loss1+loss2 最佳订报量superz,最小损失量ave_loss_min (newsvender)

图像压缩的功能，提取图像信息以及最后的图像增强(image enhancement)

说明：  基于matlab颜色特征图像检索的颜色特征的提取(Matlab color feature based on the color image retrieval feature extraction)

把图像二值化的代码，阈值为求去红色篮球的，如果是其他颜色，只需要修改相关阈值即可。(The image binary code, the threshold is seeking to red basketball, if it is other colors, just change the threshold value can be related.)

扩频通信，从电磁波利用来看，与一般现有的常规通信方式完全不同。扩频通信利用伪随机编码把信息数据（窄带信号）的频谱进行扩展，形成宽带的低功率谱密度信号发射，使用不同的伪随机序列编码，不同通信用户可在同一频段、同一时间工作，互不影响或干扰极小地进行通信。(Spectrum, from the electromagnetic waves used term, and the general existing conventional means of communication is entirely different. Spread spectrum communication using pseudo-random code to the information data (narrowband signal) to extend the spectrum, the formation of low-power spectral density broadband signal transmission, using different pseudo-random sequence of coding, different communication users at the same frequency band, at the same time work, mutual does not affect or interfere with a very small way to communicate.)

关于图像处理中的区域能量是matlab算法，此算法简单易行(Regional energy for image processing matlab algorithm, this algorithm is simple)

The Fourier transform, named for Joseph Fourier, is an integral transform that operates on the mathematical representation of a function in time and produces a function in frequency. The term Fourier transform customarily refers to both the transform operation and to the function it produces.
