opencv4.3
自主选择性的查看一幅图像中的部分区域的颜色直方图:允许用户在一幅图像中选择一个矩形区域,通过按住鼠标键画一个矩形,当鼠标放开是,高亮显示矩形框,同时在另一个独立的窗口中,使用画图函数画一个图表(选定区域的颜色直方图),分别用蓝,绿,红表示选中区域中每种颜色的像素数量。(Self-selective color in an image to view a partial area of the histogram: Allows the user to select a rectangular area in an image by holding down the mouse button to draw a rectangle when the mouse is released, the highlighted rectangle, Meanwhile in a separate window, using the drawing functions to draw a chart (selected color histogram region), respectively, with blue, green, red indicates the number of pixels in the selected area of each color.)

MeFrm
说明: 傅立叶变换在图像处理中的重要作用:
(A) 图像增强与图像去噪
绝大部分噪音都是图像的高频分量,通过低通滤波器来滤除高频噪声;边缘也是图像的高频分量,可以通过添加高频分量来增强原始图像的边缘;
(B) 图像分割与边缘检测
提取图像高频分量
(C) 图像特征提取
形状特征:傅里叶描述子
纹理特征:直接通过傅里叶系数来计算纹理特征
其他特征:将提取的特征值进行傅里叶变换来使特征具有平移、伸缩、旋转不变性
(D ) 图像压缩
可以直接通过傅里叶系数来压缩数据;常用的离散余弦变换是傅立叶变换的实变换;
(Fourier transform in the important role of image processing:
(A) image enhancement and image denoising
Most of all images of high frequency noise by low pass filter to filter out high frequency noise edge is the image of the high frequency components can be enhanced by adding high frequency components to the edge of the original image
(B) Image segmentation and edge detection
High frequency components extracted image
(C) image feature extraction
Shape features: Fourier descriptors
Texture: directly through the Fourier coefficients to calculate the texture features
Other features: The characteristic value extracted by Fourier transform to the characteristics of translation, scaling, rotation invariance
(D) image compression
Fourier coefficients can be directly compressed data commonly used discrete cosine transform is the Fourier transform of the real transformation
