Background/Objectives: During the transform and quantization process in HEVC, there are a lot of zero blocks. The coding time of transform and quantization can be considerably decreased by effectively detecting all zero blocks. Methods/Statistical analysis: This work proposes all uniform quantizer and RDO quantizer zero block detection techniques. Findings: The energy concentration property of DCT is used to suggest an improved transform coefficient estimate approach. Low frequency DCT coefficients are estimated using the Hadamard transform, while the maximum magnitude of high frequency DCT coefficients is estimated using a SATD-based technique. There will be an explicit threshold which can be used to compare the float quantization level of coefficients, and all zero blocks in the uniform quantizer may be effectively found. The stair-like thresholds for RDOQ are obtained through statistical analysis, which makes AZB identification easier. Improvements/Applications: The experimental result shows that uniform quantizer’s coding time can be cut in half, and 40% coding time can be reduced for RDOQ.

Background/Objectives: The purpose of this study is to reveal the fairness of the student party's investment in various cities and Taoism, and put forward the corresponding improvement plan. In education finance, one of the parts that many scholars pay attention to and constantly debate is how much finance needs to be invested in order to achieve successful education results. Methods/Statistical analysis: The equity level of education expenditure is an important factor for successful educational achievement. It is very meaningful to analyze the fairness of students' personal education finance. Findings: After diagnosing the fairness of the current inter regional student investment, give a reasonable improvement plan for educational finance in relatively low areas, and put forward the distribution and development direction of student educational finance in the future First, from 2013 to 2014, the per capita investment of students between regions of the Municipal Department of education was a little unequal, which needs to be improved. Second, we should improve the unfairness of the per capita investment in facility fees of students in various regions. Improvements/Applications: It is necessary to evenly distribute the per capita investment and labor cost investment of students to the municipal and municipal education departments. Fourth, it is necessary to analyze the investment amount of each student for follow-up research.
