When working with OpenCV Python, images are stored in numpy ndarray. To get the image shape or size, use ndarray.shape to get the dimensions of the image. Then, you can use index on the dimensions variable to get width, height and number of channels for each pixel. In the following cod...
img = cv2.imread('image.jpg') # Get the image dimensions (h, w) = img.shape[:2] # Calculate the center of the image center = (w // 2, h // 2) # Rotate the image by 45 degrees M = cv2.getRotationMatrix2D(center, 45, 1.0) rotated = cv2.warpAffine(img, M, (w, h)) ...

在进行三维重建之前,我们需要将医学图像数据转换为体素化表示。体素化是指将三维空间划分为小的立方体单元,每个单元称为一个体素(Voxel)。VTK库提供了vtkImageData类来表示体素化数据。 voxel_data=vtk.vtkImageData()voxel_data.SetDimensions(image_data.GetDimensions())voxel_data.SetSpacing(image_data.GetSpacing...

Each band has the same dimensions as the image dimensions. Therefore, an RGBA image of size 100x100 pixels is represented by a 100x100x4 array of values.The mode of an image describes what type of image you’re working with. Pillow supports most standard modes, including black-and-white (...
