用matlab计算并成图形的电路设计中幅频=相位响应图 ，也可为设计计算带通滤波器的中心频率以及Q值提供参考(Using matlab calculation and circuit design graphics in amplitude frequency = phase response, are also available for reference for design and calculation of the bandpass filter with center frequency and Q value)

This method usually increases the global contrast of many images, especially when the usable data of the image is represented by close contrast values. Through this adjustment, the intensities can be better distributed on the histogram. This allows for areas of lower local contrast to gain a higher contrast. Histogram equalization accomplishes this by effectively spreading out the most frequent intensity values.
