I don't think it has any effect on the program output, but what class should I put the public static void main(String[] args) { //... } method in my program? Is it better form to create a separate class, or put it in a class that does something else? If I should put it in a class that does something else, which one? Does it matter? This is really just a conventions thing. Normally
我不认为它对程序输出有任何影响,但我应该把什么课程放在这里 public static void main(String[] args) { //... } 方法在我的程序中? 创建一个单独的类,还是将它放在一个可以做别的事情的类中是更好的形式吗? 如果我应该把它放在一个可以做别的事情的班级,哪一个呢? 有关系吗? 这实际上只是一个约定的事情。 通常我会创建一个单独的类,或者将它放在与gui有关的类中,但我想知道正确的方法。 如果您正在编写
I want to detect the 4 corners of the document in android. Iam using opencv library. Iam using the following approach- (1) grayscale the image (2) Apply median blur (3) Apply adaptive threshold (4) Canny Edge detection (5) find contours (6) find the largest contour (7) get the edges and corners of the largest contour My code is srcImg = Utils.loadResource(this, R.drawable.test1, Highgui.CV_
我想在android中检测文档的四个角落。 Iam使用opencv库。 Iam使用以下方法 - (1)灰度图像(2)应用中值模糊(3)应用自适应阈值(4)Canny边缘检测(5)查找轮廓(6)找到最大轮廓(7)获取边缘和角点最大的轮廓 我的代码是 srcImg = Utils.loadResource(this, R.drawable.test1, Highgui.CV_LOAD_IMAGE_COLOR); Imgproc.cvtColor(srcImg, srcImg, Imgproc.COLOR_BGR2GRAY); Imgproc.medianBlur(srcImg, srcImg, 9); Imgp
I have a maze such as the below: XXXOOOOX OXXXOXOE OXXOOXXO OSXOXXXO XOOOXOOO //X = wall //O = path //S = startpoint //E = endpoint I want to transcribe this to a graph (adjacency matrix) but am unsure in my attempt to do so. An adjacency matrix is a list of lists of booleans, with true representing a takeable path and false representing an impossible path (eg. (0,-1) in the maze cannot conne
我有一个迷宫,如下所示: XXXOOOOX OXXXOXOE OXXOOXXO OSXOXXXO XOOOXOOO //X = wall //O = path //S = startpoint //E = endpoint 我想将其转录成一个图(邻接矩阵),但我不确定这是为了做到这一点。 邻接矩阵是布尔表列表,其中true表示可接收路径,false表示不可能路径(例如(0,-1)在迷宫中不能连接到(7,-1) (0,0是最左上角的节点))。 我不知道如何转录这个,我最好的猜测是将每个元素放在一个列表中,然后是一个具
maze http://i60.tinypic.com/1491gzn.jpg The problem i am having is the 2 pixel width pathways (the white parts). In the top-left of the image (the darker black part) i have manually gone over the white parts that were 2 pixels in width/height; there are two solutions (that i can think of). to programmatically edit it so that pathways are 1x1; to find a way of dealing with paths that are
迷宫http://i60.tinypic.com/1491gzn.jpg 我遇到的问题是2像素宽度的路径(白色部分)。 在图像的左上角(较黑的黑色部分),我手动扫过宽度/高度为2像素的白色部分; 有两个解决方案(我可以想到)。 以编程方式编辑它,使路径为1x1; 找到一种处理大于1x1的路径的方法。 任何建议,迷宫解决算法(tremaux)我已经实现了1x1路径的作品,但我正试图将其应用于这个更大的迷宫。 最好寻找一种适合迷宫的解决方案,其中
I need to implement a directional weighted median filter in Java to remove random impulse noise. I have no idea how/where to start. The algorithm is as per below: Create a 5x5 window Consider 4 directions (vertical, horizontal, diagonal left, diagonal right) from the center pixel (5 pixels in each direction) Calculate weighted difference and take the minimum value Minimum value is compa
我需要在Java中实现一个方向加权中值滤波器来消除随机脉冲噪声。 我不知道如何/从哪里开始。 该算法如下所示: 创建一个5x5窗口 考虑中心像素的4个方向(垂直,水平,左斜,右斜)(每个方向5个像素) 计算加权差值并取最小值 最小值与阈值进行比较: 如果值>阈值:它是噪声像素 否则:它不是噪点像素 计算每个方向5个像素的标准偏差 对标准偏差最小的方向给予额外权重,计算加权中值 噪声像素被替换为这
I am trying to implement some image processing using OpenCV and Java to extract a card out of an image. Following is my approach: Convert to BGR image Convert to GRAY image Apply GaussianBlur Apply Canny Edge detection Dilate Find contours Find the largest contour Find corners of the largest contour using approxPolyDP Getting a top-down view of the cropped image along the larg
我正在尝试使用OpenCV和Java实现一些图像处理,以从图像中提取出一张图像。 以下是我的方法: 转换为BGR图像 转换成灰色图像 应用GaussianBlur 应用Canny边缘检测 膨胀 找到轮廓 找到最大的轮廓 使用approxPolyDP查找最大轮廓的角点 沿着最大轮廓获取裁剪图像的自顶向下视图 在步骤8,我面临一些问题,因为我没有得到适当的角落/顶点。 以下示例图像显示了该场景: 原始图像 边缘检测和扩张后。 (
After using canny edge detector my image looks like Then I use Hough transform to extract line. Sometimes I able to find four line. But sometimes Same line detect as two line. I want to find four corner of the rectangle, so using hough transformation I try to take four line then solve them. But extra line gives me pain. How I can solve this problem. For hough transformation I'm usin
使用Canny边缘检测器后,我的图像看起来像 然后我使用霍夫变换来提取线。 有时我能找到四条线。 但有时候同行检测到两行。 我想找到矩形的四个角落,所以使用hough变换我尝试取四条线然后解决它们。 但额外的线条让我很痛苦。 我如何解决这个问题。 对于hough转换,我使用http://vase.essex.ac.uk/software/HoughTransform/HoughTransform.java.html的修改代码
I want to implement object detection in license plate (the city name) . I have an image: and I want to detect if the image contains the word "بابل": I have tried using a template matching method using OpenCV and also using MATLAB but the result is poor when tested with other images. I have also read this page, but I was not able to get a good understanding of what to do from that
我想在车牌(城市名称)中实现对象检测。 我有一个图像: 并且我想检测图像是否包含单词“بابل”: 我曾尝试过使用OpenCV的模板匹配方法,也使用MATLAB,但在使用其他图像进行测试时结果很差。 我也读过这个页面,但是我不能很好地理解该怎么做。 任何人都可以帮助我或一步一步地解决这个问题吗? 我有一个项目来识别车牌,我们可以识别和检测数字,但我需要检测和识别这些单词(与更多汽车相同的单词) 您的问题非常
