A layout algorithm based on image processing is proposed for solar cell fragments, aimed at less waste and a maximization of utilization. Firstly, image preprocessing and edge recognition are conducted on raw image to extract the cell area. Then, layout algorithm is adopted to divide the cell fragments into small rectangles and optimize the arrangement mode. Finally, layout of the cutting path for...
Multiscale Geometry Analysis consistent with the best features of the image representation, is effective for high dimensional function approximation and can use the image of the geometric regularity. In this article, we will mainly discuss the transformation of the Beam let based on Multiscale Geometry Analysis, formulate its theoretical basis, and by Matlab simulation results show the advantages...
Community detection is now playing a significant role in the discovery of underlying structures of social networks. This problem has been proved to be very hard and not been satisfactorily solved yet. Most of the algorithms proposed so far tend to maximize the number of intra-cluster edges, but ignore the importance of the core nodes within clusters. In contrast, this paper proposes a core-based algorithm...
Corner detection is an important step in the image processing of machine vision. An improved algorithm is proposed in this paper following the analysis on the existing corner detection algorithms and on the localization precision and computation efficiency in the Harris corner detection algorithm. In this algorithm, a large number of irrelevant points are rejected by statistical analyzing the pixel...
Many networks, including social and biological networks, are naturally divided into communities. Community detection is an important task for the discovering underlying structure in networks. GN algorithm is one of the most influential detection algorithms based on betweenness scores of edges, but it is computationally costly, as all betweenness scores should be repeatedly computed once an edge is...
This paper proposes a new multi-layered image coding algorithm based on wavelet and matching pursuit transforms. The original image is divided into smooth and edge layer and texture layer, Different compression algorithms of coding are adopted to each different layer in order to achieve optimization for the entire image. Case studies have demonstrated that this coding method can capture texture and...
