To randomly convert an image to grayscale with a probability, we apply RandomGrayscale() transformation. It's one of the transforms provided by the torchvision.transforms module. This module contains many important transformations that can be used to perform different manipulations on the image data.RandomGrayscale() accepts both PIL and tensor images or a batch of tensor images. A tensor image is a PyTorch Tensor with shape [3, H, W], where H is the image height and W is the image width. A batch of tensor images is also a torch tensor with [B, 3, H, W]. B is the number of images in the batch.Syntaxtorchvision.transforms.RandomGrayscale(p)(img)If ... Read More
To crop an image at a random location, we apply RandomCrop() transformation. It's one of the many important transforms provided by the torchvision.transforms module.The RandomCrop() transformation accepts both PIL and tensor images. A tensor image is a torch tensor with shape [C, H, W], where C is the number of channels, H is the image height and W is the image width.If the image is neither a PIL image nor tensor image, then we first convert it to a tensor image and then apply RandomCrop().Syntaxtorchvision.transforms.RandomCrop(size)(img)where size is the desired crop size. size is a sequence like (h, w), where h ...

To crop a given image into four corners and the central crop, we apply FiveCrop() transformation. It's one of the transformations provided by the torchvision.transforms module. This module contains many important transformations that can be used to perform different types of manipulations on the image data.FiveCrop() transformation accepts both PIL and tensor images. A tensor image is a torch Tensor with shape [C, H, W], where C is the number of channels, H is the image height, and W is the image width.

To randomly change the brightness, contrast, saturation and hue of an image, we apply ColorJitter(). It's one of the transforms provided by the torchvision.transforms module. This module contains many important transformations that can be used to manipulate the image data.ColorJitter() transformation accepts both PIL and tensor images. A tensor image is a PyTorch tensor with shape [C, H, W], where C is the number of channels, H is the image height, and W is the image width.This transform also accepts a batch of tensor images. A batch of tensor images is a tensor with [B, C, H, W]. B is ... Read More
To crop an image at its center, we apply CenterCrop(). It's one of the transforms provided by the torchvision.transforms module. This module contains many important transformations that can be used to perform manipulation on the image data.CenterCrop() transformation accepts both PIL and tensor images. A tensor image is a PyTorch tensor with shape [C, H, W], where C is the number of channels, H is the image height and W is the image width.This transform also accepts a batch of tensor images. A batch of tensor images is a tensor with [B, C, H, W]. B is the number of ... Read More
To convert a Torch tensor with gradient to a Numpy array, first we have to detach the tensor from the current computing graph. To do it, we use the Tensor.detach() operation. This operation detaches the tensor from the current computational graph. Now we cannot compute the gradient with respect to this tensor. After the detach() operation, we use the .numpy() method to convert it to a Numpy array.If a tensor with requires_grad=True is defined on GPU, then to convert this tensor to a Numpy array, we have to perform one more step. First we have to move the tensor to ... Read More
To mark strikethrough text in HTML, use the … tag. It renders a strikethrough text. HTML deprecated this tag and it shouldn’t be used in HTML5. As an alternative, use the CSS text-decoration property.To use the CSS property, use the style attribute. The style attribute specifies an inline style for an element. The attribute can be used with the HTML tag. Just keep in mind, HTML5 does not support the tag, so the CSS style should be used.ExampleYou can try to run the following code to mark strikethrough text in HTML HTML Strikethrough text ...

To mark superscripted text in HTML, use the … tag. Just keep in mind both the opening and closing tag is mandatory while using the ... tag.The superscript text appears to be half a character above the normal line. It is displayed as a smaller font.You can try the following code to mark superscripted text in HTML. Here, we are writing the value 2 4 using the tag, HTML text superscript Heading Value: 2 4 = 16 Output
Secure Sockets LayerSecure Sockets Layer (SSL) is a protocol for encrypting and authenticating data transferred between a web server and an application. When you or your users enter data on your site, it passes via several touch points before arriving at its eventual destination. Without SSL, this data is transferred as plain text, intercepted, or altered by hostile parties. SSL provides point-to-point encryption to ensure data security during transmission.A message authentication code, or MAC, is included in SSL connections to ensure that data is not lost or altered during transmission. This ensures that the data sent is received without being ... Read More
