Higher order local auto-correlation (HLAC) can be used to analyze the different types of complicated data by limiting orders and spatial displacements. In this paper, the basic concept of HLAC is introduced firstly. Then, we analyzed the HLAC based methods from three aspects: algorithm robustness, pattern improvement, and the changes of image functions which participate in the autocorrelation operation. Finally, the applications of HLAC-based methods are discussed.

Color space conversion (CSC) is an important kernel in the area of image and video processing applications including video compression. CSC is a compute-intensive time-consuming operation that consumes up to 40% of processing time of a highly optimised decoder. Several hardware and software implementations for CSC have been found. Hardware implementations can achieve a higher performance compared with software-only solutions. However, the flexibility of software solutions is desirable for various functional requirements and faster time to market. Multicore processors, especially programmable GPUs, provide an opportunity to increase the performance of CSC by exploiting data parallelism. In this paper, we present a novel approach for efficient implementation of color space conversion. The proposed approach has been implemented and verified using computed unified device architecture (CUDA) on graphics hardware. Our experiments results show that the speedup of up to17×can been obtained.

Lab-scale iron removal experiments were carried out in a batch 2-L autoclave to investigate the variables such as temperature, gas kind, for a better option for removal of iron in hot acid leach liquor in zinc conventional process. Experimental results showed precipitation temperature and duration is the most important factors, followed by pressure, and finally gas kind and stirring rate. Under a reasonable precipitation conditions: gas kind, air; temperature, 130oC; pressure, 0.8 MPa; duration, 15 min, iron precipitation yield reached 75.12%. Iron precipitation is relative pure and therefore it can be marketable.

Zinc neutral leaching residue from conventional roast-leach-electrowin often contains a considerable content of germanium. In two-stage leaching process (weak acid leaching and hot acid leaching), dissolution yield of germanium as well as zinc is low due to the compact structure of the residue. In the paper, an attempt of increasing their dissolution yield was made by pretreatment of mechanical activation. The experimental results obtained show that the activated residue has much faster leaching kinetics, and that according to current technical standard operating in Yunnan Chihong Zinc & Germanium Co., Ltd, dissolution of germanium and zinc is increased by 18.12% and 22.93%, respectively. The increase may mainly be due to the structure deformation of the residue by further investigation.

Lab-scale germanium co-precipitation with ferric hydroxide in dilute sulfuric acid media was studied. The experiments of co-precipitation of germanium and ferric hydroxide were performed by neutralization of the germanium-ferric sulfate solution via adding calcium hydroxide powder. The variables affecting the germanium precipitation yield were investigated. The experimental results show that high initial germanium concentration, high ferric/germanium molar ratio, high final solution pH, low ion strength and slow temperature will contribute to high germanium precipitation yield.

The animation industry, a creative industry, known as the most development potential sunrise industry in the 21st century, will become the new economic growth point. It is confidential relation between industry and education in case of personnel supply and demand. The assessment modality, which is one of the principal means of testing the quality and primary of teaching, in the culture of animation talent is discussed in this paper. By analyzing the situation of course examination, the new ideas of assessment modality are proposed as follows: creating design capability as a precondition, it enables students to meet the needs of society for the purpose of sustainable development. Through the adoption of flexible assessment system, it cancels that paper is everything. Based on the quality of classroom tasks, assessment model in the process evaluation is paid attention to emphasize to better achieve the objectives of personnel training.
