QUESTION
ANSWER
Answered 2022-Apr-02 at 01:41So what I did was I installing another library that's called gcv by vcaesar. There was a method called FindAllImg and what I need just provide two image, one is the source image, in my case a screenshot, and the other is a template image that needed to be searched in the screenshot.
QUESTION
I was playing with VS code settings (I wanted to explore VS Code) and suddenly the code editing got changed. Previously the code was more colourful and there were different colours for different keywords. Now my code is mostly white. Please help me to get back to default code formatting settings.
...ANSWER
Answered 2022-Jan-26 at 07:40To revert the settings completely, open the settings JSON file by bringing up the command palette (Ctrl+Shift+P) and running the command Preferences: Open Settings (JSON)
. Delete everything in there and save the file.
However, you might just have switched to a different theme by accident. To check that, open the theme chooser (Ctrl+K, T) and try the other themes.
QUESTION
The kernel size of 3D convolution is defined using depth, height and width in Pytorch or TensorFlow. For example, if we consider a CT/MRI image data with 300 slices, the input tensor can be (1,1,300,128,128), corresponding to (N,C,D,H,W). Then, the kernel size can be (3,3,3) for depth, height and width. When doing 3D convolution, the kernel is passed in 3 directions.
However, I was confused if we change the situation from CT/MRI to a colourful video. Let the video has 300 frames, then the input tensor will be (1,3,300,128,128) because of 3 channels for RGB images. I know that for a single RGB image, the kernel size can be 3X3X3 for channels, height and width. But when it comes to a video, it seems both Pytorch and Tensorflow still use depth, height and width to set the kernel size. My question is, if we still use a kernel of (3,3,3), is there a potential fourth dimension for the colour channels?
...ANSWER
Answered 2022-Jan-25 at 00:59Yes.
Actually the convolution operation occurring in a CNN is one dimension higher than its namesake. The channel dimension is always spanned by the entire kernel though, so there's no sliding along the channel dimension. For example, a 2D convolution layer with kernel size set to 5x5 applied to a 3 channel input is actually using a kernel of shape 3x5x5 (assuming channel first notation). Each output channel is the result of convolving the input with a different 3x5x5 kernel, so there is one of these 3x5x5 kernels for each output channel.
This is the same for videos. A 3D convolution layer is actually performing a 4D convolution in the same way. So an input of shape 1x3x300x128x128 with kernel size set to 3x3x3 will actually be performing 4D convolutions with kernels of shape 3x3x3x3.

Answered 2022-Jan-24 at 08:50Usually that type of images are generated by using Carbon (https://carbon.now.sh/), or similar tools (eg. silicon: https://github.com/Aloxaf/silicon).
An alternative, using R, is the carbonate
package (https://yonicd.github.io/carbonate/), which will read the code from a file, submit it to Carbon, and save it to an image. You can then add that image to your Rmarkdown document.
QUESTION
I am using MATLAB I would like to plot a colourful trajectory on top of a grayscale png image whilst retaining the colour information of the trajectory. For example with the data below, I would like to plot Data B over Image A. Without Data B turning gray and without making the colourbar represent the grayscaled image. Any help would be greatly appreciated!
...ANSWER
Answered 2021-Sep-21 at 01:22MATLAB doesn't seem to like to do more than one colourmap pet axes. By using hold on
we're plotting both the image (gray colormap) and surface (e.g. jet colormap) to the same plot. By default from the non-RGB image in imshow the colormap is set to gray, and so it is the same for the surface plot. Trying to change the colourmap by invoking colormap('jet')
changes the colormap for both the image and surface.
Seems that there have been others with the same problem: https://uk.mathworks.com/matlabcentral/answers/194554-how-can-i-use-and-display-two-different-colormaps-on-the-same-figure
The best solution appears to be defining two seperate axes to the same figure and linking them so that positional information matches. You need to specify which axis to plot to, so imshow
has been replaced with imagesc
which has more flexibility.Then you can define a different colourmap to each axis. Unfortunately, the colorbar probably won't play ball everytime so you gotta fiddle with its positional information a bit.
In practice for your code:
QUESTION
Below is a figure I have created for a single set of data, with contours plotted over the top. This is exactly what I need, I just need it plotting as a series of subplots for my 7 model runs, with the colourful salinity data, and the contours plotted over the top.
However, when I try to do the subplots, I can get in the salinity data, but I cannot plot the contours on top (or the colorbar, but that's another issue). Ideally, this should look like 7 mini versions of figure 1. However, I get the following error:
...ANSWER
Answered 2021-Sep-07 at 08:19Your example contour data is way over off the coast of Africa, so I changed that a little to make it in the same area your example salinity data. (maybe you used the example "lons" twice, also for the "lats"?)
QUESTION
I am preparing a new layout with slanted elements that should be responsive in any way. What I currently have does look good on default desktop and mobile, but if the screen is larger, the layout is being ruined: e.g. on my 32" screen the text is starting outside the container elements, right before the slanted elements. That should not happen.

QUESTION
so I am trying to achieve the following design:
Specifically the colourful badges on top. Now these items are grouped and can be any number. In the picture they are grouped into 2 but they can easily be 4 or 5.
I wanted a way to programmatically change the background and text colour of each badge for each group.
I have tried soo many things that haven't worked for me, at best I am currently only able to get the first colour to change.
