see IE scored a significant lead in Chrome and Firefox, hoping this score will enable Google and Mozilla to further improve browser performance. It will be a very good sign that the browser market is again in a healthy competitive state. Fortunately, the performance of each browser is excellent-I think only a small number of games can have more than 10000 screen sprites.The last advantage of IE11 support for WebGL is in retro games. for games that use pixel graphics, it is important that you zo
the scene, letter is the letters in the word (word), and the ball class is the particle in the letter. Originally I directly omitted the letter class, but later found that the typing process, the alphabet is a corresponding, color a change, so letters are essential.When each frame is rendered, four classes are sequentially called by the draw method and the Update method, with a bit of recursion meaning, after all, the ball class for draw and update.Explain a few key methods:

Super-sampling is a spatial anti-aliasing method that eliminates aliasing (jagged and pixelated edges) from rendering images on computer games or other computer programs. Unlike real objects, which have a continuous smooth curve, the sawtooth is generated because the computer shows a large number of squares to the visitors. These "Pixels" are the same size, each with a color. A line can only be displayed as a set of imagers, so there is a sawtooth, un
derivative of the smooth processing. In this semester I also chose the course of graphics, in which I used a lot of similar smooth processing, such as pixelated screen display, surface display, polygon chamfer and so on.# # # Iterative methodPersonal feeling, the iterative method is the center of Computer computing method, it is also possible that I had little contact with this idea, I feel that this kind of thought is worthy of reflection and promot

Make sure the foreground is segmented as far as possible from the background (that is, no pixelated or distorted characters).
Apply a text offset correction to the input image to ensure that the text is aligned correctly.
Now, we apply OCR to the following sample image. (First you need to download the sample image in the original link, the original link is given below)Go to your project path and enter the following command in your
size. If you then specify a size in the CSS, such as 600pxx200px, then the original 300x150 canvas expands to that size, so all the content drawn in the canvas expands accordingly. It's a behavior. When you specify a new width and height for an image, the image is stretched or shrunk if it is larger or less than the actual width and height of the original image. If you magnify it, you'll get a pixelated effect in the image, right? The canvas is the s

Last class, we mainly introduced the feasibility of machine learning. First of all, the NFL theorem shows that machine learning is seemingly unworkable. However, after the introduction of statistical knowledge, if the sample data is large enough, and the number of hypothesis is limited, then machine learning is generally feasible. This lesson will discuss the core issues of machine learning, and strictly prove why machines can learn. Starting from the

The so-called inductive preference induction bias is the preference of machine learning algorithms for certain types of assumptions in the learning process.
An effective machine learning algorithm must have an inductive preference, otherwise it will not produce a definite learning result . such as
