正常图像到高清图像转换器.. !!!! [英] normal image to HD image convertor ..!!!!

问题描述

大家下午好..

我们的项目是开发一个将普通图像转换为高清图像的软件，但我不知道该怎么做。我打算用c＃使用asp.net。



有人能帮助我吗？

我是初学者使用c＃ 。

Good afternoon everyone..
Our project is to develop a software that convert normal image to HD image but I don''t know how to do this. I''m going to use asp.net with c#.

Can anyone help me?
I''m beginner in using c#.

推荐答案

我想你可以增加图像的分辨率，但无论你做什么，它都会显得很糟糕，因为你不能神奇地创造新的数据填补额外空间。您可以做的最好的事情是根据周围的数据猜测像素值应该是什么。无论哪种方式，这都没有意义。你还必须定义普通和高清是什么。

I suppose you could "increase" the resolution of an image, but no matter what you do it will look crappy because you can''t magically create new data to fill in the extra space. The best you can do is make a guess as to what the pixel values should be based on surrounding data. Either way, this doesn''t really make sense. You also have to define what "normal" and "HD" are.

你知道你在问什么吗？你想做什么？



我觉得是时候坐下来告诉你图像处理的事实：刀锋和CSI不是真的。你无法放大人眼照片中的光线图像，也不能在相机后面50米处读取车牌。



当你拍摄正常图像比如640像素乘480你不能只是放大它并看到以前隐藏的像素。它们不存在。如果要将640x480图像转换为1920x1440，则必须将原始图像中的每个像素转换为9个像素，为它们指定颜色，使它们与周围像素相匹配，并生成聚合值，即原始像素。 />


你最终得到了什么？高清图像？不会。你最终会以更高的分辨率获得原始图像的像素化副本。



特别是如果你是初学者，那么开始一点点，一个项目是你可以做 - 因为如果你试图这样做，你会很快变得沮丧！

Do you have any idea what you are asking? What you are trying to do?

I think it''s time to sit you down and tell you the facts of image processing: Blade runner and CSI are not real. You cannot magnify the image of a light in a picture of somebody''s eye and read the numberplate of the car 50m behind the camera.

When you take a "normal image" at say 640 pixels by 480 you can''t just enlarge it and see the pixels that were "previously hidden". They do not exist. If you want to convert a 640x480 image to 1920x1440 then you have to convert each pixel in the original image into 9 pixels, assigning colours to them so that they fit with the surrounding pixels and generate an aggregate value which is the original pixel.

And what do you end up with? A HD image? No. You end up with a pixelated copy of the original image at a higher resolution.

Particularly if you are a beginner, start a little smaller, with a project that you can do - because you will quickly become frustrated if you try to do this!
