Sensor – Actual effective Bayer color resolution

Because in a typical digital camera, each pixel only records one color through the use of a Bayer filter or a similar mechanism to get a view of the colors, the actual resolution of a ## megapixel sensor is actually lower, even after applying interpolation.

Anyone have data on true effective resolution and how it is determined? I have seen several posts online that said it was reduced by 1 / sqrt (2), but they did not explain why. Suppose an optimal interpolation method (or a typical "good" method that is commonly used).

html – Single page websites, page resolution

so first user on the site, so a little context.
I am learning html / css / java to create websites quickly, I mainly focus on building my portfolio of atm websites, the early stages, I only copied a few things.

Here's the question: I loaded my web page to my laptop, it's okay, each page is contained in the screen resolution. However, he loaded it on a mac at university and each page boundary overlaps the screen resolution … IF I explain it pretty well .. my website aims to have different pages, all on one file so you can scroll down to find content, but I want it to be large enough to cover all screen resolutions or adjusted for each user . Here is my code to help you:

Limit the resolution of the image on the download file for the specific domain woocommerce

when i add a product, i have a form with two fields "upload file".
(product image field) and (product gallery image field).

when the user uploads an image for the first field (product image field), I want to limit the size of the image to (640 * 640 max).

And when it uploads an image for the second field (product gallery image field)
I want to limit the size of the image to (300 * 300 max).

Is it possible to define different sizes for two specific fields?

Please note that I am using the media editor download for wordpress

resolution – Photo book printing – is the text printed differently?

Computer-generated text has sharp, smooth edges because the pixels on the edges have calculated opacity. It is (improperly) called "anti-aliasing".

If you put the text in your photo, it becomes a bunch of pixels and its size will change if the photo is scaled for printing (which is often the case). Scaling of an image is done by interpolating the pixels (i.e. a pixel in the result is a "mix" of pixels around its position corresponding in the source). The scaling algorithm does not know that the edge pixels are anti-aliasing pixels and applies the same interpolation algorithm as on the image.

Interpolation always introduces a slight blur so that the text can become blurry. The image can be sharpened to eliminate blurring, but the high-contrast edges of the text "react too much" and show artifacts. So, anyway, the edges of the text are no longer smooth and clean and our eyes are pretty good at noticing.

On the other hand, if the text is separated from the image, it can be kept as text data and rendered to the final size after the image has been scaled for the image. 39; printing, so that its edges are not subject to degradation. In some printing processes, they might even use techniques similar to sub-pixel rendering.

So, in theory, keeping the text separate can give better results. But it could depend on the actual printing process, and maybe the edge degradation can be experienced anyway.

Unity WebGL HTML5 – The resolution is necessarily scaled

While downloading HTML5 test versions of my game from and NewGrounds, I noticed a problem with the resolution. In every resolution setting area I can think of (HTML5 build resolution, host site integration resolution, index file canvas, even my computer registry linked to "DefaultCompany"), I have set my game to 720 x 480. In the Unity editor and as a standalone version of Windows it will display at this correct resolution. However, when I download the HTML5 version, it seems to be scaled to 900 x 600, which makes the game look more blurry as it is always rendered at the smaller and expected resolution.

I tried to create a new Unity project and change the resolution first, but the same problem happened. Based on this, I think the problem has nothing to do with the build file which keeps an older or default resolution setting.

And the solution is not as simple as giving up and just setting the resolution to 900 x 600. I tried it, and it scaled it up even more. So it seems that publishing Unity in HTML format will always increase the resolution.

I have no idea how to fix it. Anyone have any idea what might be going on?

How to get the best image resolution from srcset

I have an image code with srcset and sizes like this:

    Multitronics TC 750

How to get the maximum image size (like Multitronics-TC-750.jpg 1260w) using the function? For example wp_calculate_image_srcset ()?

Did President Fat Bastard underestimate the Aryan resolution?

You need more than enriched uranium to neutralize NY, you need an ICBM to launch Iran to NY. WE also have the technology to fire many ICBMs directly from the sky, so to properly attack the United States you must have several that you can fire at the same time in the United States.

The REAL problem is that they are attacking Israel. Either will make them become a glass bowl instantly. Israel has nuclear weapons and so do we.

Anyway, what you just showed is that we have to eliminate the Iranian government and take away its capabilities as long as we can.

This has been John Bolton's argument for a long time. Hillary Clinton even declared that she would invade Iran if she were president.

Trump, despite all the shit the press has said, is actually against it and is trying to avoid war.

Edit: Also, the likelihood of nuking Israel is rather low, as the 3rd holiest place in the Muslim faith is in Israel.

Attacking Israel is certainly possible, but covering them up is rather problematic for their faith.

Is there a way not to change the resolution of the images downloaded in Magento

We had a problem that each time we upload a product image in our Magento administrator> Catalog> Manage products> Product information> Images, its resolution went from 900 dpi to 96 dpi, making our downloaded image of poor quality. I have attached 3 images including one before downloading enter description of image here, another is posted in our Magento administrator enter description of image here, and the other is the different resolution between before and after the downloaded images enter description of image here.

Is there a way not to change the resolution of the downloaded image?

Any help is appreciated!



differential equations – Resolution of ODE vs VoronoiMesh

The following example uses my package, IGraph / M.


First, we generate random points to use as Voronoi centers. We apply some Lloyd relaxation steps to make them more distant.

pts = RandomReal({-1, 1}, {100, 2});
 pts = PropertyValue({VoronoiMesh(pts, {{-1, 1}, {-1, 1}}), {2, All}}, MeshCellCentroid),

Here is our mesh, representing the cells:

mesh = VoronoiMesh(pts, {{-1, 1}, {-1, 1}}, 
  MeshCellStyle -> {1 -> White})

enter description of image here

We will simulate the diffusion between cells. For this, we need the Laplacian matrix (also called Kirchhoff matrix) from their neighborhood graph.

ag = IGMeshCellAdjacencyGraph(mesh, 2);
km = IGKirchhoffMatrix(ag)

IGraph / M provides IGMeshCellAdjacencyGraph to construct the neighborhood graph of meshes of different dimensions, IGMeshCellAdjacencyMatrix to build the corresponding adjacency matrix (faster), and IGKirchhoffMatrix to get the Laplacian graph. There is more information about these functions in the package documentation (IGDocumentation()).

Let's create random initial concentrations:

initC = RandomReal({0, 1}, MeshCellCount(mesh, 2));

Then solve the diffusion equation using NDSolve:

diffConst = 1.0;
solfun = NDSolveValue({c'(t) == - diffConst * km.c(t), c(0) == initC}, c, {t, 0, 1})

We can animate the solution like this:

 SetProperty({mesh, {2, All}}, MeshCellStyle -> ColorData("Rainbow") /@ solfun(t)),{t, 0, 1}

resolution – The external screen does not fill the screen

I am using a Mobile Pixels DUEX PRO as an external screen for my Mac laptop, and at normal resolution, everything is too small (see the first photo). I tried to change the resolution, but all that ends up happening is that the screen goes down, but does not fill the screen, and everything is still too small to be read. (second photo)
How can I decrease the screen resolution while making it fill the screen? Thank you!
