Description: 学习使用OpenCV，对输入的一段彩色视频，用OpenCV实现以下功能或要求:
1. 对输入视频的每一帧图像都用同一个阈值进行二值化；
2.在每帧二值化图像上叠加上含自己学号与姓名等信息的版权字幕；
3. 在处理的过程中，实时显示每帧图片处理之后的效果；
4.将所有这些二值化图像按视频原来顺序合成输出一个视频文件，按原输入视频播放速度的两倍合成；
5. 做成如下的命令行格式，xxx.exe 输入视频文件名 二值化阈值 输出视频文件名（例如 MyBiVideo.exe input.avi 50 output.avi ）
这里的二值化有两种选择，可以手动收入阈值，也可以直接用OTSU算法的较优阈值直接二值化。-Learn to use OpenCV, for some color video input, with the OpenCV following functions or requirements:
1. Each frame of the input video images are binarized using the same threshold value
2. superposed on the binarized image of each frame containing the copyright on the number and the name of their own learning subtitles other information
3. During processing, real-time display after processing each frame
4. All of these binarized image by synthesizing the video output of a video sequence of the original document, the original input composite video playback speed twice
5. made the following command line format, xxx.exe input video file name binary threshold value of the output video file name (eg MyBiVideo.exe input.avi 50 output.avi)
Here there are two binary choice, you can manually income thresholds, you can directly use the optimum direct binarization threshold through OTSU algorithm. Platform: |

Description: This program takes a color monochrome image and lets the user interactively/manually threshold the monochrome image, or a single color band of a color image, via sliders to set the maximum and minimum thresholds. The thresholded image is a binary image that can be used as a mask image for other images. The pixels in the thresholded range are shown in the middle image as a binary image (black/white), and the original image pixels are shown masked in the left image (gray scale or color). Inputs are the low and high thresholds to start with and the image file name or image matrix. The program returns the threshold values and the last color band that was used to the threshold. The image can be of type integer (uint8, uint16, etc.) or floating point (single, double)-This program takes a color or monochrome image and lets the user interactively/manually threshold the monochrome image, or a single color band of a color image, via sliders to set the maximum and minimum thresholds.

Description: A binary image is a digital image that has only two possible values for each pixel. Typically, the two colors used for a binary image are black and white, though any two colors can be used. The color used for the object(s) in the image is the foreground color while the rest of the image is the background color.[1] In the document-scanning industry, this is often referred to as bi-tonal .-A binary image is a digital image that has only two possible values for each pixel.

Description: Edge detection is widely used in image processing, image recognition and computer vision. Tradition edge detection
methods have a lot of disadvantages. This paper presents a new edge detection algorithm base on Matching Pursuit
(MP). Our method has four steps. Firstly, the color image is converted to gray Image. Secondly, the residual part of
Matching Pursuit algorithm with the Wavelet Packet dictionary is extracted. Thirdly, the Gaussian Filter is applied to
remove the additional parts of the previous image and finally, the Ostu’s thresholding method converts image to
binary form. We compared our algorithm with the tradition methods like Prewitt, Sobel, Laplacian of Gaussian (LOG)
and Canny operators. Results show that our algorithm has high value of Performance parameters such as PR, PSNR
and FOM compared to other algorithms. Platform: |
