In the H264 standard, the core of the coding layer is the macro block, a macro block size of 16x16, a 16x16 brightness block, and two 8x8 chroma blocks for commonly used 4:2:0 sampling formats. corresponding to the similar structure in HEVC is the coding tree Unit (CTU), its size can be specified by the encoder, the maximum can be supported to 64x64, the minimum can be supported to 16x16. For high-resolution video encoding, using a larger size of

CTU is the LCU. It is a new concept introduced by h.265. it is similar to the previous macro block of video codecs. The size of CTU can be 16x16, 32x32, 64x64, you can set h.265 to select the CTU you need. CTU selection and bit rate andAlgorithmThere is a mutually restrictive relationship between the complexity and the

first time a ruler is connected from left to right, 1, 2, and 3, the matching conditions are met, but a single 3 is also qualified, and the number is smaller. So pay attention to this: when we get a value that meets the condition, we need to add a value to its starting point until it does not meet the condition. At this time, we will continue to add one to the end and then enumerate. In the previous steps, when conditions are met, the start point equals the end point to continue enumeration. Co

Question and question: (a little difficult to read ...) A sequence of numbers is given to locate a range. When two identical numbers in the interval are deleted, only the sequence between the two numbers is retained, and the same number is deleted, ask how many delete operations can be performed at most. For example: Therefore, two delete operations are performed. Ideas: The key to interval DP is to determine which small intervals are converted from a large interval. When a [l] = A [R, DP [l] [

Never really understood the concept of GOP .The video sequence is composed of several time continuous images, which are divided into several small image groups and GOP when compressing them. There are two types of GOP in video encodingClosed GOP, each GOP starts with an IDR image, and each GOP is encoded independently of each otherThe first GOP in the development GOP is the IDR image, the first of the subsequent GOP is the NON-IDR image, that is, the image of the GOP after the inter-frame predic

the explanation of the noun in HEVC noun explanation In order to understand the details of the HEVC encoder, it is necessary to have a clear understanding of the following nouns. 1) LCU A coded image is usually divided into a number of basic units that can be set at their own size, called LCU (largist Coding unit). The size of the LCU can be set to a range of 16x16-64x64. 2) Slice The slice is a sequence of CTU in a frame-by-raster scan sequence, one
