Nevertheless, some multi-display systems have to sacrifice the bit-depth to support connections from tens or hundreds of screens because limited numbers of pins are available in the central processing chip. These reductions on bit-depth of color will definitely degrade the quality of the display. To solve this issue, we present a spatiotemporal dithering method which is able to extend the color depth and improve the display quality. The key idea in the proposed method is to utilize frame rate control in spatial dithering which is Floyd-Steinberg dithering in our case. This spatiotemporal dithering method takes advantage of both spatial and temporal dithering, bringing in an extension on the color depth and an improvement on the display quality without flicker problems. After implementing the hardware circuits for a multidisplay system on a FPGA device, we find that our spatiotemporal dithering method is efficient and effective, outperforming other spatial methods under the circumstances of limited color depth.","PeriodicalId":143221,"journal":{"name":"The 2014 2nd International Conference on Systems and Informatics (ICSAI 2014)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122607216","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of this research is to develop a vision-based top-view system to expand drivers' field of view. Four cameras provide a 360-degree view of the surrounding terrain of the vehicle, and the destination image is composed by these four processed images. In this paper, we divide the procedure into 4 parts, fisheye lens distortion correction, inverse perspective transformation, image mosaicking and pixels mapping table creation. Every part is achieved by one-to-one mapping between pixels, so most of the calculation has been done on PC. The experimental results show that, the final image is clear, natural and have very good real-time performance. It can effectively reduce the blind spots of drivers, and it has a strong value for research and practical.","PeriodicalId":143221,"journal":{"name":"The 2014 2nd International Conference on Systems and Informatics (ICSAI 2014)","volume":"134 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122460523","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, the working principle of inter-core communication, and the principal means of communication between multi-core processors conducted in-depth research. For the current advantages and disadvantages of the existing communication structure, we propose task assignment based on shared memory inter-core communication model(TASMCM), reducing communication delay of die-to-die, ensuring consistency of data synchronization, to improve the capacity of multi-core processors in parallel.","PeriodicalId":143221,"journal":{"name":"The 2014 2nd International Conference on Systems and Informatics (ICSAI 2014)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115904071","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Firstly, the input image is decomposed by redundant Laplace transformation. Then, in the multiscale images, nonlinear diffusion is used. For nonlinear diffusion in each sub-image, an image gradient index is automatically determined by weighting the image gradient indexes of all the sub-images. To test the validity of the proposed algorithm, the typical methods of directly nonlinear diffusion and adaptive wavelet filter were used for comparison.

In this system, the input is an image of vehicle and the vehicle will be identified automatically, it can also retrieve images which are similar to the input image. 3742 vehicle images which include 28 types of vehicles are collected as the image database. Features of these images are extracted and quantized as “visual words” which are clustered so that every vehicle model is represented by a set of “visual words”. A hessian-affine detector is used to detect the features of the input image and the SIFT descriptor transforms each feature into a 128-dimensional vector which is finally quantized as a “visual word”. In this way, the input image is transformed into a set of “visual words”. By matching the “visual words” between the vehicle model and the input image, it can compute the similarity and judge the type of the input vehicle image. For the vehicle retrieval, the “visual words” is weighted in the method of “TF-IDF” to compute the cosine similarity of two images. The retrieval results are ranked by cosine similarity. The experiments show that the precision of vehicle recognition is above 85%, and the using of “bag of words” is much faster than the traditional features matching.","PeriodicalId":143221,"journal":{"name":"The 2014 2nd International Conference on Systems and Informatics (ICSAI 2014)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127236903","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
