Opencv expand dims
Did you know?
My tensorflow model expects images to have shape: [1, 1080, 1920, 3] and i'm trying to reshape frame that i captured from video. It seems easy to do it using python and numpy: np.expand_dims (frame, axis=0) But I have no idea how to do it on c++ using Mat from opencv. Any ideas? c++ opencv tensorflow Share Improve this question Follow http://www.iotword.com/5246.html
Web13 de mar. de 2024 · 这个问题是一个Python代码问题,np.expand_dims()函数是用来扩展数组的维度的。在这个代码中,它将img数组在第3个维度上扩展了一个维度,使其变为一个3维的数组。这个操作通常用于将灰度图像转换为RGB图像,即将一个二维的灰度图像变成一个三维的RGB图像。 WebFirst, make a new Mat type data 256*256. Second, fill the image with the average value of small image. Third, copy the small image in the middle of the new image.
