问题 This question has already been asked before, but the asker didn't provide enough information and left unanswered and I am curious about the program. Original Question Link I'm trying to do a sobel edge detection using both opencv and cuda library, the sobel kernel for X direction is -1 0 1 -2 0 2 -1 0 1 I have 3 files in my project main.cpp CudaKernel.cu CudaKernel.h main.cpp #include <stdlib.h> #include <iostream> #include <string.h> #include <Windows.h> #include <opencv2\core\core.hpp>

问题 I have a .jpg image captured from a webcam. It is a greyscale image. I need to convert the image to a string of its pixels like so: "255 232 45 678 56 23....345 76 44 767 433 345" How do I go about doing this? Also, would changing the size of the image change these values? 回答1: Assuming you have the image represented as a numpy array (since the question is tagged as OpenCV related, then this is likely the case), then to obtain the result you want, I'd take the following steps. First flatten

问题 I have a list of urls in a text file.i want the images to be downloaded to a particular folder ,how i can do it.is there any addons available in chrome or any other program to download images from url 回答1: Create a folder in your machine. Place your text file of images URL in the folder. cd to that folder.

问题 I am currently creating an MVC 4 web application. I have an action that has a base background image which is always the same then an arrow image which changes in degrees depending on the information that is collected within the action. I call this action using <img src="@Url.Action("trend-image", "NonReg_Reports")" alt="background" width="245" height="105" /> This works fine when it is called and is just displaying a HTML webpage. It gives me the HTML. <img src="/nonreg-report/01495344/trend

问题 I have trouble getting images in React Native to work as I want. Because images in RN are decoded natively in a separate thread, React Native displays the images that are used in my components (background images, handles, knobs, sliders) at different times, after each individual image has loaded - instead of showing the whole component at once, when it's ready. I'm using the require method to render the images: <Image source={require('./component-bg.png')} /> <Image source={require('./handle
