它所描述的是不同色彩在整幅图像中所占的比例，而并不关心每种色彩所处的空间位置，即无法描述图像中的对象或物体。颜色直方图特别适于描述那些难以进行自动分割的图像。(It describes the proportion of different colors in the entire image, and does not care about the spatial location of each color, that is, it can not describe objects or objects in the image. Color histograms are especially suitable for describing images that are hard to segment automatically.)

说明：  分析音频，分割进行傅里叶变换，得出声谱图(Analyze the audio and get the spectrogram)

图像去噪处理的TV全变分模型的Matlab代码实现(TV image denoising processing model of the entire variational Matlab code)

数字图像处理中的基本形态学处理，如腐蚀、膨胀、开操作、闭操作等实现的源代码。可以自定义结构元素的形状。(Digital image processing in the basic morphology processing, such as corrosion, swelling, open operation and close operation to achieve the source code. You can customize the shape of structural elements.)

C标准函数源码，十分丰富，便于移植和裁剪。(C standard function source code, is very rich, easy to transplant and tailoring.)

说明：  bp人工神经网络模式识别教程示例，研究人脸识别 手势识别有帮助(bp nervel network trainning and recognition ,e.g:face & dynamic hand gesture detection and face recognition .I hope it would be very useful for researcher !)

先检测出椭圆，然后对椭圆进行椭圆拟合，画椭圆。(First detected in an oval, and then carried out on the elliptical ellipse fitting, painted oval.)
