The characteristics of H .
The 4:2:0 supports encoding and decoding of continuous or interlaced video. The basic concept of H .
1. Macro BlockIn video coding, an encoded image is usually divided into a number of macro blocks , a macro block consisting of a luminance pixel block and an additional two chroma pixel blocks . In general, the luminance block is a 16x16-sized block of pixels, and the size of the two chr
Forum, The digital display interface standard is established.DVI Digital terminal than the standard VGA terminal signal is better, the digital interface to ensure that all content in digital format transmission, to ensure that the host to monitor the transmission of data integrity (no interference signal introduction), you can get a clearer image.Standard video input (RCA) interface: Also known as AV interface, usually is a pair of white audio interface and yellow video interface, it is usually
macro pixel consisting of two pixels adjacent to each other horizontally requires 4 bytes of memory (2 bytes of brightness, two shades per 1 bytes). .The following four pixels are: [Y0 U0 V0] [Y1 U1 V1] [Y2 U2 V2] [Y3 U3 V3]The stored stream is: Y0 U0 Y1 V1 Y2 U2 Y3 V3Mapped pixel points: [Y0 U0 V1] [Y1 U0 V1] [Y2 U2 V3] [Y3 U2 V3](3) YUV 4:1:1The chroma sampling of the 4:1:1 is a 4:1 sampling of the chroma

The current market of the mouse is mostly USB interface, we buy plug on the use, seems very good also no problem. But in fact, many brand mouse manufacturers have their own products equipped with a dedicated driver application package, these packages are not simple for the mouse installed on the driver, such as Logitech Microsoft, such as peripherals manufacturers also through the supporting applications to enable the mouse to achieve a lot of additional functions, such as the mouse button funct
Lei Snake (Razer) released the 2016 new WIN10 game this blade Pro, configuration luxury, including the Intel sixth Daicouri I7-6700HQ processor, 17.3-inch 4K resolution display, 32GB DDR4 memory, maximum 2TB SSD solid-state hard disk storage, NVIDIA GTX 1080 graphics card, Thunderbolt 3.0 transmission interface, full-size mechanical keyboard.
In addition, the Lei Snake Blade Pro is equipped with three USB 3.0 connectors, supports NVIDIA G-syn

ASUS Zenbook Prime Series has been the market's most lightweight ultra-polar products, and touch ux31a-bhi5t on this basis to add a touchscreen design, so that it is more in line with the market trend. Configuration, the Intel third Daicouri i5 processor, 13.3-inch 1080P Ful

bs = 2: At least one 8x8 block on both sides of the boundary belongs to intra, and if the conditions of bs=2 are met, no bs=1 judgment is made; bs = 1: At least one 8x8 block has a non-0 residual coefficient, and the boundary is the TU boundary; BS = 1: The absolute difference of the motion vectors of the two blocks is gr
Always keep the video data YUV, because different type definitions are derived from different companies based on the organization of their products, and derive a number of different YUV formulas.Broadly, YUV from the pixel organization in the form of dots, there are two: 1.planer states. 2.packet status.Planar Mode example: Y0y1 .... Yn u0u1 ... Um V0V1: VM,YUV three channels of continuous storage;Example of packet mode: Y0u0v0 + y1u1v1 + ... + YNUNVN,YUV three channels mixed storage.The planar

The use of integer-based spatial transformations can increase the computational speed (using only addition and displacement operations), but the use of integer transformation to the
Before you know what brand of mechanical keyboard is good, let's take a look at the mainstream mechanical keyboard brand. Domestic common mechanical keyboard brands have Leibo, Internet Express, Plum, PLU and so on. Foreign mechanical Keyboard brand, there are well-known cherry, in addition, like Sai (Denmark), Razer (USA), Filco (Japan), Noppoo (United States), are mechanical keyboard enthusiasts well-known brands.

intra-frame prediction blocks were specified: 4*4, 8*8, and 16*16, and intra-frame prediction blocks for chroma components were based on 8*8 size blocks. The brightness blocks of the 4*4 and 8*8 sizes contain 9 predictive modes (vertical, horizontal, DC, lower left diagonal mode, right down diagonal mode, vertical right mode, horizontal down mode, vertical left mode, and horizontal up mode), while the 16*16-size brightness blocks and 8* The 8-size
The YUV color model is derived from the RGB model, which is characterized by the separation of luminance and chroma, which is suitable for the field of image processing.YCbCr model is derived from YUV model, applied to digital video, ITU-R BT.601 RecommendationThrough the above comparison can be determined that we are in h.264,mpeg and other coding standards in the YUV is actually ycbcr, we do not confuse the name.In order to reduce the amount of data

Value, fractional sample interpolation is used to generate the
Prediction samples for Noninteger sampling positions. As in
H.264/mpeg-4 AVC, HEVC supports motion vectors with
Units of one quarter of the distance between Luma samples.
In addition to the MV with integer values, the pixel interpolation is used to generate the predicted pixels for neighboring pixel positions.

To the photographic enthusiasts to share a detailed analysis of the Canon 7D camera evolution of high ISO speed noise reduction function.
Share list:
Key points for flexible application:
1, using a tripod shooting, even if the night scene photography can be in the ISO 3200 will be "NR" set to "close" to retain sharp detail performance.
2, raw imaging is the key to skilled use of noise reduction level. Adjust the parameters, the decision is priority to reduce noise or detail performance.
