Convert Cimg to ITK

由 非 Y 不嫁゛ 提交于 2019-12-03 18:15:52
问题 I'm trying to convert a Cimg image to itk image to use it for registration algorithm. The Cimg is a RGB image and i want to convert it to RGB itk image. Her is my code : void Cimg_To_ITK (CImg<uchar> img) { const unsigned int Dimension = 2; typedef itk::RGBPixel< unsigned char > RGBPixelType; typedef itk::Image< RGBPixelType, Dimension > RGBImageType; typedef itk::ImportImageFilter< RGBPixelType, Dimension > ImportFilterType; ImportFilterType::Pointer importFilter = ImportFilterType::New();

X11 Problems when using CImg header in XCode on Mac OSX 10.11.6

问题 I added X11 to my header search paths, library search paths, and I linked the binary to the X11 library in the build settings and build phases in XCode however I am still getting the errors shown in the picture below. I am 99.999% Sure the problem is X11 because when I disable the display capabilities the warnings aren't there. Any ideas on what I can do next? 回答1: I think you have your build settings a little incorrect. Here is a very simple program to get you started - you can choose to

Loading PNGs with CImg

问题 I am unable to load PNGs with CImg. I've heard you need to get libpng / zlib to get to work first but I am unsure how to set this up. I am on Ubuntu. My source: #include <cmath> #include <cstdio> #include <string> #include <assert.h> #include <stdarg.h> #define cimg_using_png #include "CImg.h" using namespace cimg_library; #include "png.h" int main(int argc, char** argv) { CImg<unsigned char> img2("test.png"); img2.display(); return 0; } 回答1: Close, but you need #define cimg_use_png and add

Create video from array of pixel values in C++

由 99封情书 提交于 2019-12-01 01:48:40
Does anyone know of a method to save a sequence of pixel values, stored in an array to a video? Currently I'm using Cimg to visualise a simple n-body simulation, whilst I can save each iteration to an image file, this is very slow. Any suggestions on a similar library for handling video would be appreciated. Essentially, I just want to record what's displayed in the Cimg window I create to a video file. The program is written in C++, on linux, compiling with g++. The fact that I can run the simulation and record it running with screen capturing software would seem to imply it's possible, but I

How do I capture and Process each and every frame of an image using CImg library?

由 大憨熊 提交于 2019-11-30 19:25:17
问题 I'm working on a project based on real time image processing using CImg Library in Raspberrypi. I need to capture images at higher frame rates (say atleast 30 fps), when I use the inbuilt Raspicam commands such as sudo raspistill -o -img_%d.jpg -tl 5 -t 1000 -a 512 /* -tl : time lapse duration in msec -t : total time duration (1000 msec = 1 sec) -a : displays frame numbers */ with this command though it shows 34 frames per second,I could only capture maximum of 4 frames/images (and rest of

How to get rgb value by cimg?

问题 CImg<unsigned char> src("image.jpg"); int width = src.width(); int height = src.height(); unsigned char* ptr = src.data(10,10); How can I get rgb from ptr ? 回答1: From the CImg documentation -- section 6.13 on page 34, and section 8.1.4.16 on page 120 -- it looks like the data method can take four arguments : x, y, z, and c: T* data(const unsigned int x, const unsigned int y = 0, const unsigned int z = 0, const unsigned int c = 0) ...where c refers to the color channel. I'm guessing that if
