对于一幅输入图像，将产生一幅输出图像，输出图像的每个像素点的灰度值由输入像素点决定，将感兴趣特征的对比度扩展使之占据可显示灰度级的更大部分。使一输入图像转换为在每一灰度级上都有相同的像素点数，均衡化会减少灰度级数。大多数自然图像由于其灰度值分布集中在较窄的范围之内，引起图像细节不够清楚。采用直方图修正后可使图像的灰度间距拉大或使灰度均匀分布，从而增大了反差，使图像细节清楚，达到增强的目的。(For an input image, will produce an output image, the output image gray value of each pixel from the input pixel decided to expand interest in the contrast of features to make it account for more gray levels can be displayed most. Make an input image is converted to grayscale in each pixel have the same points, equalization will reduce the gray series. Most natural images because of their gray value distribution concentrated in a narrow range, causing the image detail is not clear enough. Make the image histogram revised by the gray space widening or so gray uniform distribution, thereby increasing the contrast between the image details clear objective to achieve enhanced.)

Chebyshev1IIRdigitalfilter
这是本人夏季学期的课程设计：模拟信号数字化滤波处理的计算仿真-Chebyshev I型低通滤波，对模拟信号进行数字化滤波处理。根据数字滤波器的性能指标，计算出Chebyshev1型低通IIR数字滤波器的系统函数，画出数字滤波器的频率响应曲线，给出Chebyshev1型低通IIR数字滤波器的设计结果。(This is my summer semester of the curriculum design: analog signal processing digital simulation filtering-Chebyshev I-type low-pass filtering, on the analog signal to digital filter processing. Digital filter in accordance with performance indicators, calculated Chebyshev1-type low-pass IIR digital filter systems function, to draw the digital filter frequency response curve, give Chebyshev1 type low-pass IIR digital filter design.)
