coding compression ratio and transmission reliability, which has been widely used in digital TV broadcasting, real-time video communication, network streaming media and other fields. two. Introduction to the video coding method of H.
In terms of the overall coding framework, H. E still uses a structure similar to the previous standard, that is, the block structure of the hybrid coding framework. The main structure of the diagram is as follows:
The h image of each frame is encoded into one or mo

In simple terms,Yuv:luma (Y) + chroma (UV) format, typically sensor supports YUV422 format, that is, the data format is output in y-u-y-v orderRGB: Traditional red-green-blue format, such as RGB565, whose 16-bit data format is 5-bit R + 6-bit G + 5-bit B. G more than one, because the human eye is more sensitive
even 1/8 pixels is further adopted in H. That is, the displacement of the true motion vector may be 1/4 or even 1/8 pixels as the base unit. Obviously, the higher the precision of motion vector displacement, the smaller the residual error between frames, the lower the transmission code rate, that is, the higher the compression ratio.The interpolation of the 6-order FIR filter is used to obtain a 1/2-pixel position value in H. When the 1/2 pixel value is obtained, the 1/4 pixel value can be obta

I. Overview:"Internet of Excellence" is the completion of this series of programs, the project is a software company's actual research and development projects, in the case of non-infringement of copyright, we have to do a little modification and upgrade, to do our learning materials, the teacher will lead you to realize the core function of this project, all the source code will be given to you. This project data structure is complex and reasonable, the module is numerous and each has the chara
using a gold-plated design, so as to prevent rust, always ensure smooth contact.
In addition, just mentioned 87 key keyboard, so-called 87 keys refers to only the keyboard area functional area, no keypad of the standard keyboard. Another standard keyboard with a keypad is usually 104 keys, the mechanical keyboard will add a lot of suitable for custom buttons, which we can see from the number of keys.

If you want a mechanical keyboard, here are a few things to consider:1. Tap Feedback: You can easily use the mechanical keyboard when you are clearly feeling the impact of the switch, that is, the so-called percussion sense.2.PS/2 or USB: This slightly understand the computer's people know that the older keyboard and mouse are basically PS/2 interface, is now basically universal USB, so there is no need to be too tangled in this, anyway, the converter can also buy.3.NKRO (Key Rollover): Nkro, si

Thanks to the Haswell processor and Nvidia Optimus Technology (which can be used to complete day-to-day operations with an integrated Intel HD 4600 video card), Snake Blade 14 gained 8 hours and 7 minutes of endurance in a regular notebook battery test (via WiFi), The average level of light and light notebooks is 2 hours higher than the Dell Alienware 14 (5 hours and 17 minutes). However, the MSI GE40, which also sup
When using the mouse, how to find out how to move too fast, how to adjust? Do not know the students to take a look at this article.

corrected image problems, such as color adjustment and sharpen filters.Core Image analyzes the quality of an image and provides a series of filter to optimize and adjust these, such as chroma, contrast, and hue.The Core image recognizes the face features of still images and can track them in video images. Knowing where your face is, you can decide where to apply the filter.3. Core image has a built-in filter related document. You can query the system
