Witryna2 sie 2024 · If you want to define an 4x4 grayscale image, you need to define your input in this way: x = torch.rand ( (1, 1, 4, 4)) # (batch_size, channel, height, width) res = F.interpolate (x, scale_factor= (2, 2), mode='nearest') res.shape # [1, 1, 8. 8] And if you want to work on a 3D image (your scale_factor is 3D at least): WitrynaIf you are enlarging the image, you should prefer to use INTER_LINEAR or INTER_CUBIC interpolation. If you are shrinking the image, you should prefer to use INTER_AREA interpolation. Cubic interpolation is computationally more complex, and hence slower than linear interpolation.

"WitrynaIf size is an int, the smaller edge of the image will be matched to this number maintaining the aspect ratio. i.e, if height > width, then image will be rescaled to ( size × height width size). Note In torchscript mode size as single int is not supported, use a sequence of length 1: [size, ]. " - Imresize image height width interp nearest

WitrynaResizing by Specifying Width and Height. In this first example, let’s resize the image by specifying a new width and height that will downscale the image. In the code below: We set the desired width as 300 and the desired height, 200. These two values are combined in a 2D vector, required by the resize () function. Witrynaw (int, required) – Width of resized image. h (int, required) – Height of resized image. interp (int, optional, default=1) – Interpolation method (default=cv2.INTER_LINEAR). Possible values: 0: Nearest Neighbors Interpolation. 1: Bilinear interpolation. 2: Bicubic interpolation over 4x4 pixel neighborhood. 3: Area-based (resampling using ...
