C++OpenCV3源代码resize函数用法
引用和分别是关于使用OpenCV库中的cvResize函数进行图像缩放的示例代码。cvResize函数可以将一个图像缩放至指定尺寸。在引用中的代码示例中,首先加载一张名为"1.jpg"的图像,然后对其进行缩放,并创建一个缩放后的图像dst,最后显示原始图像和缩放后的图像。在引用中的代码示例中,出现了一个错误,错误信息为"OpenCV(4.2.0) ..\modules\imgproc\src\resize.cpp:4045: error: (-215:Assertion failed) !ssize.empty() in function 'cv::resize'",这个错误的原因是输入的图像尺寸为空。在引用中的代码片段是为了计算缩放比例而计算的fx的值。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
