YUV main sampling format

] [Y2 U0 V2] [Y3 U0 V2] (4) yuv4: 2: 0 Doesn't mean only y, CB, and no Cr component.It means that for each scanned line, only one color component is stored at a sampling rate of 2 to 1. Adjacent scan lines store different color componentsThat is to say, if a row is, the next row is, And the next row is, and so on. For each color component, the sampling rate in both the horizontal and vertical directions is, so the color sampling rate is. For a non-compressed 8-bit video, each macro pixel cons

form a macro pixel. 4:2:0: This sample does not mean that there is only Y,CB and no CR component, where 0 of the U,v component is sampled once. For example, the first line sampled 4:2:0, the second line sampled 4:0:2, and so on ... In this sampling mode, an average of 1.5 bytes per pixel is consumed. 4:2:2 Example If the original data three pixels is [Y0 U0 V0], [Y1 U1 v1],[y2 U2 v2],[y3 U3 V3] After 4:2:2 sampling, the data becomes Y0 U0, Y1 V1, Y2 u2,y3 V3 [Y0 U0 v1],[y1 U0 v1],[y2 U2 V3], [

, and all sides of the graph are positive, it is certainly not possible to pass through the third vertex, making the V1 vertex to the V3 vertex shorter. Because the distance from the V1 vertex to the other vertices is certainly not v1 to the V3 vertex short.OK, since the shortest path of a vertex is determined, below we will be based on the new vertex V3 would have a degree, found to V3 for arc Tail: So dis[3] to be updated to 60. This process has a professional term called "slack". That is, V1

Introduction to Windows IPSec

During main mode negotiation, two computers establish a secure and authenticated channel. First, the following IPsec policy parameters are negotiated: The encryption Algorithm (DES or 3DES), the integrity algorithm (MD5 or SHA1), the Diffie-hellman group for the base key material (group 1, Group 2, or group 2048 in Windows Server 2003) ) and authentication Methods (Kerberos V5 protocol, public key certificate, or preshared key). After the IPSEC polic

My path to the soft test (v)--data structure and algorithm (3) diagram

the graph is a nonlinear structure as well as a tree. I look a little complicated. In fact, it's very easy. The tree has a hierarchical relationship, and the upper element is able to connect to the next number of elements. But only one element of the upper layer can be connected. In the graph structure, the connection between nodes is arbitrary, regardless of what element can be connected with other elements. The diagram is relatively easy, we only introduce the graph of the traversal and minima

Windows2000 Dynamic DNS security considerations

, security dynamic updates are only available when the Active Directory is integrated with the DNS region. What does security dynamic update mean? In Windows, it means that the ACL of the Active Directory is used to set the permissions of users and groups to modify the DNS region and/or its resource records. To allow updates to the DNS region and/or its resource records, dynamic updates also use secure channels and authentication in addition to ACL. Windows2000 supports security dynamic updates

Pandas dataframe data frame

A Data box is a two-dimensional data structure, similar to a table in SQL. Data boxes can be constructed using dictionaries, arrays, lists, and sequences. 1. If the dictionary data box is created, the column name is the key name: d = {‘one‘:pd.Series([1,2,3],index= [‘a‘,‘b‘,‘c‘]), ‘two‘:pd.Series([1,2,3,4],index=[‘a‘,‘b‘,‘c‘,‘d‘])}print(pd.DataFrame(d)) 2. List creation data box: d = pd.DataFrame([[1,2,3,4],[5,6,7,8],[10,20,30,40],[50,60,70,80]],columns=[‘V1‘,‘V2‘,‘V3‘,‘V4‘])print(d) 3. Colu
