Motion detection results
If you double-click the Switch block so that the signal is connected to the SAD side, the Video Viewer block displays the SAD values, which represent the absolute value of the difference between the current and previous image. When these SAD values exceed a threshold value, the demo highlights the quadrant in red.
Note that the difference image itself may be viewed, in place of the original intensity image, along with the red motion highlighting, which indicates how the SAD metric works. Platform: |

Description: 这是关于SQL，ORACLE，方面的书
In the Introduction and Chapter 1, PL/SQL Concepts, you learned about t
difference between machine language and a programming language. You have
also learned how PL/SQL is different from SQL and about the PL/SQL basic block
structure. This is similar to learning the history behind a foreign language and in
what context it is used. To use the PL/SQL language, you have to learn the
keywords, what they mean, and when and how to use them. First, you will
encounter the different types of keywords and then their full syntax. Then you
will expand on simple block structure with an exploration of scope and nesting
blocks-This is about SQL, ORACLE, aspects of the book In the Introduction and Chapter 1, PL/SQL Concepts, you learned about t difference between machine language and a programming language.

Description: 为提高基于块的运动预测的搜索精度,该文基于块匹配准则,提出最小绝对差分误差和(SADD)算法。SADD 以 SAD 为基础,利
用块匹配中相邻像素点误差之间相关性,将块内各像素误差按一定顺序进行差分,消除了相邻点误差之间的冗余。该算法更精确地表达了
块与快之间的相似程度。实验结果表明,该算法可有效降低码率,提高 PSNR 值,而且其鲁棒性好,可适用于各种序列。
-n order to improve the search accuracy performance of motion estimation based on block, this paper researches the block matching
algorithm, brings forward a new matching algorithm named the minimum Sum Of Absolute Different Differences(SADD). Based on SAD, the
algorithm SADD takes advantage of the relativity in the adjacent differences inside one block, adopts the difference operation in a certain order to
remove the redundancy, which enables the algorithm SADD to describe the similarity between two blocks much more accurately. Simulation result
shows that this algorithm can reduce the bitrate effectively and improve the PSNR performance well. And it can be adapted to kinds of video
sequences.
