Description: 边缘检测是数字图象处理、图象分析和识别领域中的重要课题。近年来，由于彩色图象的广泛应用，使彩色数字图象处理技术日益收到关注，彩色图象边缘检测是在众多的彩色图象处理中极为重要的方法，这是因为图象分割、识别等大量的高层次彩色图象处理均建立在低层次边缘检测的基础上。本实验是将彩色RGB图象首先转换为灰度图象，然后利用经典的边缘检测算Canny算子来实现边缘检测，然后再统计出边界方向的直方图。-Edge detection is a digital image processing, image analysis and identification of important issues in the field. In recent years, due to the extensive application of color images, so color digital image processing technology increasingly received attention, color image edge detection in color image processing a large number of extremely important ways, this is because the image segmentation, identification such a large number of high-level color image processing are built on low-level edge detection based on. This experiment is the first color RGB image is converted to grayscale images, and then use the classical Canny edge detector operator to realize edge detection, and then the statistics of the histogram of the direction of the border.

Description: 全彩色图像的色彩分量间互换。对于彩色图像，图像的颜色是由每个像素点的RGB三分量的组合决定的。本实验的实验目的就是通过调整图像像素点RGB三分量的顺序来进行图像红、绿、蓝三个颜色分量间的互相转换，从而改变图像的颜色；比如：原图像为一朵红花，经过处理之后，我们将其变成绿花或者蓝花。运用到canny算子-Full-color images between color-component exchange. For color images, color images are from each pixel RGB three-component combination of decisions. The purpose of this experiment is the experiment by adjusting the image pixel RGB three-component order image red, green and blue three color component conversion between each other, thus changing the color of images such as: The original image for a red flower, after After treatment, we will turn it into green or blue flower flower.

Description: Canny 算法包含许多可以调整的参数，它们将影响到算法的计算的时间与实效。
高斯滤波器的大小:第一步所用的平滑滤波器将会直接影响 Canny 算法的结果。较小的滤波器产生的模糊效果也较少，这样就可以检测较小、变化明显的细线。较大的滤波器产生的模糊效果也较多，将较大的一块图像区域涂成一个特定点的颜色值。这样带来的结果就是对于检测较大、平滑的边缘更加有用，例如彩虹的边缘。
阈值:使用两个阈值比使用一个阈值更加灵活，但是它还是有阈值存在的共性问题。设置的阈值过高，可能会漏掉重要信息;阈值过低，将会把枝节信息看得很重要。很难给出一个适用于所有图像的通用阈值。目前还没有一个经过验证的实现方法。(The Canny algorithm contains many parameters that can be adjusted, which will affect the time and effect of the algorithm's computation.
The size of the gaussian filter: the smoothing filter used in the first step will directly affect the results of the Canny algorithm. Smaller filters also produce less blurring, which can detect smaller, more variable lines. The larger filter produces more fuzzy effects, and the larger image area is painted as a specific point color value. The result is more useful for detecting large, smooth edges, such as the edge of a rainbow.
Threshold: using two thresholds is more flexible than using a threshold, but it still has a common problem with thresholds. The set threshold is too high and may miss important information; If the threshold is too low, it will be important to see the details. It is difficult to give a generic threshold for all images. There is currently no proven implementation method.)
