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.

[Graph program] Colorimagecolorcomponentinter-exchange

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.
