Moving objects in video sequences are highly connected and structured, which makes motion connectivity an advanced feature for segmentation. Accordingly, after sharp noise elimination, the cumulated difference image, which exhibits the coherent motion of the moving object, is adaptively thresholded. Then the maximal connected region is labeled, post-processed and output as the final segmenting mask. Hence the initial video object is effectively extracted. Comparative experimental results show that the proposed algorithm extracts the initial video object automatically, promptly and properly, thereby achieving satisfactory subjective and objective performance.展开更多

The neural network has a mesh structure in which each neuron didn't connect to all other neurons but maintain a fixed number of connections with other neurons. In training,the evolutionary computation method was used to improve the neural network performance by change the connection neurons and its connection weights. With this new model,no feature extraction is needed and all of the pixels of a sample image can be used as the inputs of the neural network. The gender recognition experiment was made on 490 face images (245 females and 245 males from Color FERET database),which include not only frontal faces but also the faces rotated from-40°-40° in the direction of horizontal. After 300-600 generations' evolution,the gender recognition rate,rejection rate and error rate of the positive examples respectively are 96.2%,1.1%,and 2.7%. Furthermore,a large-scale GPU parallel computing method was used to accelerate neural network training. The experimental results show that the new neural model has a better pattern recognition ability and may be applied to many other pattern recognitions which need a large amount of input information.展开更多

The results suggested that the duration asymmetry comes from the long decaying ENSO cases rather than the short decaying ones. The evolutions of short decaying El Nino and La Nina are approximately a mirror image with a rapid decline in the following summer for the warm and cold events. However, a robust asymmetry was found in long decaying cases, with a prolonged and re-intensified La Nina in the following winter. The asymmetry for long decaying cases starts from the westward extension of the zonal wind anomalies in a mature winter, and is further contributed to by the air-sea interaction over the tropical Pacific in the following seasons.展开更多

The contourlet transform has better performance in representing edges than wavelets due to its anisotropy and directionality,and is therefore well-suited for multiscale edge enhancement. We modify the contourlet coefficients in corresponding subband and take the noise into account for mere precise reconstruction and better visualization. We compare this approach with enhancement based on the ourvelet transform,and the traditional Histogram Stretching (HS). Our findings are that contourlet based enhancement out-performs other enhancement methods on low contrast and dynamic range images,and can clearly identify the vessels and nerves in an ophthalmic image.展开更多

According to the structure of the legend, the Eastern legend type is more ancient. In its most archaic version the sole hero spots a doe, who later turns out to be the daughter of a king, later marrying the hero and then they found a new homeland where his people may reproduce. This totemic tradition of the origins can he seen in the Hungarian myths of origin, as well as in the oral ritual texts related to wedding ceremonies which connect Central Eurasia with Europe through the Hun origin myths. The doe appearing in the Eastern Legends is the symbol of the Sun and the ancestress of the culture hero's nation. And this symbolic role descends to the cultural heritage of the Christian era later in the person of Virgin Mary. The aim of the paper is to find whether there are any correspondences between the two branches and if there are, the sort is to be determined; furthermore, the purposes of the Hungarian legends are to be sought out about the Miracle Stag in possible relation to the deer legends on the two continents linked together by the Eurasian steppes.展开更多

Thus, scientific protection strategies are urgently needed to change this status. Changbai Mountains contains one of the largest BKPFs and is considered a priority biodiversity conservation area in China. Guided by systematic conservation planning(SCP) methods and procedures, we chose representative species and communities in BKPFs ecosystem as priority conservation objects, and set quantitative conservation target, which is in the light of the biodiversity characteristic of BKPFs. The watershed area is used as planning unit. We used CPlan software to calculate the irreplaceability(Ir)value of each planning unit and the contribution value(Ti) of each conservation object to(1) assess the conservation efficiency;(2) identify the conservation gap of the existing conservation network. Then wecalculated a human disturbance index(HDI) for planning units in the conservation gaps and combine this with the Ir value to design three conservation scenarios to optimize the conservation network.Results show that planning units with high conservation value 14.16% of the total area, with3084.36 km2 were covered by the existing conservation network. 79.28% of planning units with high conservation value have not been protected which were concentrated mainly in the eight gap areas.Only 25.3% of protection objects achieved their conservation target with the existing conservation network. Conservation efficiency is low. Three conservation scenarios are constituted, each prioritizing a different aim:(1) ecological value;(2)species rescue; and(3) economical avoidance. The three conservation schemes potentially enable 93%,88% and 51% of conservation objects, respectively, to achieve identified conservation targets, thereby improving conservation efficiency significantly.展开更多

In this sense, it would be a reasonable idea that an individual should benefit from art education in order to have a complete education, since art is not just creating an aesthetic object or being aware of staying against an aesthetic object. Art means that it occurs in every stage, in every action, in all attitudes and behaviors of human being realized in an aesthetic concern without thinking When the individuals having an art education in primary and secondary education start their education in a higher education program in a faculty or department other than art education, art education loses its continuity. However art education should be continuous and it is of importance in terms of its contribution to this continuity since the studies of art education for the adults out of formal education would support it. The purpose of the current study was to determine the needs of adults and also the support that would be obtained from any kind of educational activities for art education, and to propose some recommendations in this sense展开更多

For that, the theoretical reference of the research involves the analysis of the parameters according to the aspects that involve the use interactions of packaging in agreement with the definition and scientific concepts of ergonomics, allied to the development of product projects, discussing forms, handling, load transportation and the support of the product. Therefore, improperly handling of the packaging may cause damages to the products and even potential accidents. Coding and decoding are significant to facilitate the use recognition within the individual's repertoire. The packaging, within the macro-ergonomics universe, may be the object of ergonomics, whose contribution to solve problems is related to labor activities, by dealing with packaging, transportation and load resulting from the man-object interaction. The incorrect identification of information may lead to problems of interpretation and misuse, from the handling to the disposal of packaging. For this reason, this research suggests the adjustment of the man-object interface which may lead users to make mistakes regarding use and important choices, through adequate handling actions.展开更多

These particles have a property called spin. What the spin of a particle really tells us is what the particle looks like from different directions, in other words it is nothing more than a geometrical property. The motivation for this work stems from the fact that geometry has always played a fundamental role in physics, macroscopic and microscopic, relativistic and non-relativistic. Our belief is that if a GUT (Grand Unified Theory) is to be established at all, then geometry must be the common thread connecting all the different aspects of the already known theories. We propose a new way to visualize the concept of four-dimensional space-time in simple geometrical terms. It is observed that our time frame becomes curved, just as the space-frame, in the presence of a massive gravitating body. Specifically, in the event horizon of a black hole, where time seems to grind to a halt for external observers, the time frame appears to curve in on itself, forming an imaginary loop. This results in extreme time dilation, due to the strong gravitational field. Finally we adopt a descriptive view of a GUT called Quantum Necklace GUT which attempts to connect gravity together the other three fundamental forces of nature, namely the strong, weak and electromagnetic interactions.展开更多
