OpenCV需要将IPL_DEPTH_32S转换为IPL_DEPTH_32F [英] OpenCV need to convert IPL_DEPTH_32S to IPL_DEPTH_32F

问题描述

我有一个IPL_DEPTH_32S图像(这意味着我使用32位整数表示像素)，并且需要将其转换为IPL_DEPTH_32F，以便可以应用模板匹配.有谁知道将整数转换为浮点数的公式，或者任何可以执行此操作的OpenCV内置函数?

I have a IPL_DEPTH_32S image (meaning I use 32bit integer to represent pixels) and I need to convert it to IPL_DEPTH_32F, so that I can apply template matching. Does anyone know the formula to convert the integers to floats, or of any functions built in to OpenCV that can do this?

推荐答案

我不认为opencv具有这样的功能.

I don't think opencv has such a function.

最简单的方法是创建一个与IPL_DEPTH_32S图像大小完全相同的新IPL_DEPTH_32F图像.然后遍历两个图像中的所有像素，并针对每个像素副本进行循环，然后将整数像素转换为浮点像素.

The easiest way to do this will be to create a new IPL_DEPTH_32F image with exactly the same size as your IPL_DEPTH_32S image. Then loop over all pixels in both images and for each pixel copy and cast the integer pixel to the float pixel.
