A prediction method of time recursive to confirm the shortest time of route is proposed. This method is as an accumulated experience basing on the idea of supervised learning in artificial neural network, colligating with the difference of road conditions during different time section, the human factors function, and the randomness of the accident in course of driving, thus the guidance of the traffic route is realized. Comparing with the real-time road conditions and accumulated experience, the method of time guidance prediction could offer real-time and effective road information for drivers. This guidance technology assists drivers to judge correctly in time and reduces the time losses because of the lack of the experience and the accidents. The guidance technology can be applied to the vehicles, which are with GPS. The example indicates that the model is effective combined with the real data.","PeriodicalId":333542,"journal":{"name":"2010 International Conference on Optoelectronics and Image Processing","volume":"104 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-01-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116011743","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}

A detailed description of a novel mosaic method has been proposed in the paper. Firstly, pixels re-arranging and nonuniformity verifying have been done with the images during the pre-processing step. Scene-based statistical method is applied to remove most of the nonuniformity noise. Secondly, a novel feature-based image registration algorithm is studied in the registration step. The morphological modified global thresholding algorithm is proposed to segment the two images. Then region features are extracted by 8- adjacent neighborhood labeling method. The area of the regions and the slope between their central points are used in feature matching. Thirdly, the affine transformation between the images is determined by the matched features and the information from the two images is fused to make a larger format image by the weighted-averaging method. At last, two pairs of images after pre-processing are used for registration experiment while a pair of images is registered before noise removing. The registration results are tested to be insensitive to noise and be excellent and reliable even though the images are slightly twisted. The fusion experiment is done for non-twisted images and the mosaic result shows that our method is efficient in the procedure and can meet the requirement of remote sensing image process.","PeriodicalId":333542,"journal":{"name":"2010 International Conference on Optoelectronics and Image Processing","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115672505","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}

It can superimpose white-light image on infrared thermal image to generate mixture image. The system is realized on a FPGA chip and is mainly composed of multi-channle DMA controller and image superimposition module. Multi-channel DMA controller can realize data exchange between image superimpositon module and memory independent of vehicle-loaded CPU. Image superimposition module adopts Alpha channel mixture algrithm to mix two-channel images. Equations of algrithm are modified to forms that can be easily designed on a FPGA chip.

Instead of maintaining the grey levels of original pixels and estimating the grey levels for newly added pixels, the proposed approach split the original pixel, into new pixels. Two approaches are proposed to estimate grey levels for the new pixels, namely zero order split approach and 2nd order split approach. Degraded images and low resolution images were used to test the proposed approach. Results show that the proposed zero order split approach had much better results than other approaches tested for bi-color images such as license plate image. For general images, the image enlarged by the second order split approach had higher contrast than that enlarged by the bicubic interpolation method.","PeriodicalId":333542,"journal":{"name":"2010 International Conference on Optoelectronics and Image Processing","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117225248","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}

Recently, the relationship between urban land use and urban transit becomes more and more attention by the scholars. During the process of the modification of urban space layout, it is very necessary that the industry layout and the layout of public facilities will be adjusted synchronously. That is to say that housing and working position will be matched on the aspects of scale, distribution, structure, etc, by the mode of mix-use land. To achieve the goal, the character of land use and urban land development intensity along urban rail transit, as two key elements, should be planned and controlled.","PeriodicalId":333542,"journal":{"name":"2010 International Conference on Optoelectronics and Image Processing","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127100035","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}
