Hello I m trying to convert an image from uchar to float but i get an error as Assertion failed here is my code snippet #include #include "opencv2/opencv.hpp" using namespace cv; using namespace std; Mat img = imread(img_name); if (img .empty()) { cerr << "no image"; return -1; } height = img.rows; width = img.cols; size = img.rows*img.cols; float* cpu_image = (float *)malloc((size+1) * 3 * sizeof(float)); if (!cpu_image) { std::cout << "ERROR: Failed to allocate memory" << std::endl; return -1; } //converting image from uchar to float* pixcel-wise for (int i = 0; i < height; i++){ for(int j = 0; j < width; j++) { for(int k = 0; k < 3; k++){ cpu_image[(i * width + j) * 3 + k] = img.at>(i,j)[k]; } } } cpu_image[size] = 0; cpu_image[size+1] = 0; cpu_image[size+2] = 0; //converting image back to uchar from float Mat dest(height, width, CV_32FC3, cpu_image); imwrite(out_name, dest); free(cpu_image); return 0; } Any advice pls...
