At present, the large-scale workpiece need to be measured on the coordinate measuring machine(CMM) in the manufacturing process resulting in low efficiency and hard quality controlling. In this paper, an image mosaic method for on-machine vision measurement of large-scale workpiece was presented. The camera was mounted on the numerical controlled milling machine to acquire multi-images by controlling the moving of working table. Rule of image taking, definition of overlapped image pairs, feature point detection and projective matrix computation were discussed. Image mosaic of large-scale workpiece with high precision was realized. Size measurement result proved the effectiveness and high efficiency of this method.

Multi-touch technique is a novel interactive technique that supports one finger or more to manipulate simultaneously. Thus, the bimanual interaction on the touch screen has been proved as a valuable input form with high degree of freedom (DOF). However, the drawbacks such as high error rate for target selection, hand fatigue and poor gesture extension critically limit the bimanual interaction on multi-touch environment. These drawbacks are mainly ascribed to the irrationality between hand input and software mapping, inconsistent gesture operation and immature gesture recognization techniques. In this paper1, we investigate the related literatures about two-handed interaction techniques in multi-touch devices and discuss the drawbacks of current two-handed interaction techniques. Finally, we present some promising directions for future research.

Cluster ensemble has recently become a hotspot in machine learning communities. The key problem in cluster ensemble is how to combine multiple clusterings to yield a final superior result. In this paper, an Improved Non-negative Matrix Factorization (INMF) algorithm is proposed. Firstly, K-Means algorithm is performed to partition the hypergraph’s adjacent matrix and get the indicator matrix, which is then provided to NMF as initial factor matrix. Secondly, NMF is performed to get the basis matrix and coefficient matrix. Finally, clustering result is obtained via the elements in coefficient matrix. Experiments on several real-world datasets show that: (a) INMF outperforms the NMF-based cluster ensemble algorithm; (b) INMF obtains better clustering results than other common cluster ensemble algorithms.

Cache is an important effect factor of total system performance of computer architecture. To provide references for the computer architecture designer, we put forward the relationship between the cache performance and cache parameters. Firstly, we described the main software simulation method, and analyzed various factors of effects on cache performance, and then carried out the simulation experiment of cache performance based on SimpleScalar tools set and SPEC2000 benchmark suite. We compared the effects on cache performance when cache size, cache block size and association are changed separately, and then we analyzed the experimental results in detail. The result is basically in keeping with the cache principle of architecture. At last we gave the reasonable cache parameters and conclusions.

Optimization of Constrained Functions have been a research focus in multi-objective optimization problems (MOP). Based on the technologies from NSGA-II such as non-dominated sorting, elitist strategy and niche technique, this paper proposes an improved NSGA-II algorithm for Optimization of Constrained Functions. In the improved algorithm, a partial order relation and the crossover operate by Cauchy Distribution is set up. Then according to the partial order relation, the individuals are sorted for generating the non-dominated individuals. Moreover, to enhance the evolution’s ability, some individuals are evolved in the same generation and the crossover operate by Cauchy Distribution is adopted. In addition, non-dominated individuals generated in each generation are archived to Pareto set filter to reserve all individuals with good characteristic generated in the evolving process. Finally, some Benchmark functions are used to test the algorithm performance. Test result shows the availability and the efficiency of the algorithm.

The design of the classifier is one of the important parts of the online detection system of the stored-grain insects based on the image recognition technology. The classification of the insects was of many image feature parameters, and the mixing degree among feature parameters of various species of the insects was large. The extension theory was proposed to be applied to the automatic classification of the insects. A method that constructed the matter element matrix of the insects was put forward based on the mean and variance of the image features. After calculating the correlation degrees between the insect to be recognized and the nine species of insects, the insect could be recognized by the maximum integrated correlation degree criterion. The experiment confirms that the recognition of the insects based on the extension theory is practical and feasible by the training and analyzing of the samples of the insects.
