Can I customize which image appears when my YouTube channel is shared on social media?

At the moment when I copy and paste my YouTube channel URL into Facebook, the channel icon is shown as a post picture. It would be nice to display a custom image that would look better on large sizes like Facebook posts. Is that possible? Is there a way to customize which image appears when my channel is shared on social media?

Image quality – using a full-frame camera in crop mode reduces performance in low light?

No difference in image quality at the pixel level. The better performance in poor lighting conditions of a full-frame camera is based on a larger image circle, which is filled by the light of a larger entrance pupil with the same equivalent focal length (and thus the same image). Better noise performance at the pixel level only results if you actually use this larger image circle to fill larger pixels.

A 50-megapixel full-frame camera has a similar noise performance per pixel as a 20-megapixel DX camera. If you are not pixelated and have a display device with a lower resolution than the camera, the noise with more pixels is averaged better. This depends heavily on the interpolation that the device uses. "Nearest neighbor" "Interpolation" is no average noise at all, the "box car" interpolation averages the noise to a maximum, but is rarely used due to its weak moiré pattern performance.

However, they are talking about using an FX-enabled system in DX mode. This does not waste light on cropping the end result (e.g. if you are using a premium lens and cannot move closer), but is wasting light if you only zoom in and use the full sensor and then scale it down. So if you have the ability to zoom, either because your lens is not zooming fully or because you can "zoom in" with your feet, your equipment tends to be better used in terms of light collection. Of course, at the expense of reduced depth of field. If you had to turn the lens off in full screen mode, you wouldn't be using more light anyway.

modern experience – resizing an image with the formatting of the json iist view

I'm trying to replicate the look of the news.aspx page for a custom view:

Enter the image description here

To make sure that the thumbnail keeps its aspect ratio when resizing, I decided to add the same method used on the news.aspx page: wrap the image in a width and height div and use that Object adjustment to resize the image:

"children": (
                {
                      "elmType": "div",
                      "style": {                           
                        "width": "276px",
                        "height":"154px"                            
                      },
                      "children": (
                        {
                          "elmType": "img",
                          "style": {
                            "display": "block",
                            "opacity":" 1",
                            "width": "100%",
                            "height": "100%",
                            "object-fit": "cover",
                            "position": "absolute",
                            "left": "50%",
                            "top": "50%",
                            "transform":" translate(-50%, -50%)"

                          },
                          "attributes": {
                            "src": "($BannerImageUrl)"
                          }
                        }
                      )
                    },

This just blows up the pictures and creates a mess. Can anyone confirm if this looks right before I start over?

machine learning – tensorflow image segmentation

For my image coloring project, I'm trying to get the class label for a particular pixel in an image.
For example, I want to know if a certain pixel of the image belongs to sky, person, tree, flower, ocean, etc.

I want to be able to use a pre-trained model that does this because my main goal is to implement an Image Colorizer (similar to this research report: https://link.springer.com/article/10.1007/ s11263-019-01271-4).

I watched:
https://www.tensorflow.org/tutorials/images/segmentation
and
https://www.tensorflow.org/tutorials/images/classification

but it looks like the model needs to be trained.

I'm new to Tensorflow, so everyone knows something similar. Please let me know.

I need help with my logic (resizing an image)

Hi Guys!!

I am trying to insert PHP code to resize an image.

Basically, users upload an image. And this image is pasted into a PDF document, but I have to limit how big (pixels) this image is. If the height is too high, the content is moved to the 2nd page. What I don't want

I currently have this code that works to some extent, but I want the width of the image to be more than 80 which is perfectly fine as it doesn't push the page down:

But then again, I want to make sure the width doesn't exceed 480 pixels if I want to make it smaller.

As if I want to limit the height to 80 and the width to 480 if it is larger than the aspect ratio (without distorting it) to scale to it. :(

Any help or advice would be greatly appreciated.

        function imageResize($imageResourceId,$width,$height) {
            $ratio = $width/$height; // width/height
            if( $ratio > 1) {
                $targetWidth = 80;
                $targetHeight = 80/$ratio;
            }else {
                $targetWidth = 80*$ratio;
                $targetHeight = 80;
            }
            $targetLayer=imagecreatetruecolor($targetWidth,$targetHeight);
            imagecopyresampled($targetLayer,$imageResourceId,0,0,0,0,$targetWidth,$targetHeight, $width,$height);
            return $targetLayer;
        }

bright – To make a foreground image lighter while the background of the background becomes darker

This picture shows someone holding a book. I try to make the person holding the book dark as a shadow and highlight the book to make it lighter.

I use Surething Disc Labeler and Paint 3D.

The same applies to this image: https://i.scdn.co/image/ab67616d0000b2737ba586d4dc575abd1386c619

thank you in advance
