Firstly, we compress and add noise on a high resolution image. Then, we remove noise based on PCNN within 5 neighborhoods and 3 neighborhoods. Finally, we use adaptive median filter to modify the image pixels and use the matrix conjugate gradient method to rebuild the image.

In order to meet the real-time requirements of video image defogging, this paper proposes a fast video image defogging algorithm based on the dark channel prior. Firstly, atmospheric light value is estimated by more reasonable way. Secondly, the tolerance mechanism is included for adjusting the transmission rate map in the bright areas in order to eliminate color distortion phenomenon in the bright areas of the image. Finally, by reducing the transmission rate map resolution reasonably, the calculating time is shorten but the processing effects is not affected at the same time. The experiment results show that the proposed method can get a good defogging effect.","PeriodicalId":442320,"journal":{"name":"2013 6th International Congress on Image and Signal Processing (CISP)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114570493","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}

Speckle filters commonly are adaptive filters using local statistics such as mean and standard deviation, such as the Lee and its enhanced filters and median filter. They adapt the filter coefficients based on data within a fixed moving window, and this brings in contradiction between the quality of speckle noise suppression and the capability of preserving image details. The Lee filter decreases speckle noise well in homogeneous regions, and the enhanced filter performs well both in the homogeneous and heterogeneous areas. But it does not effectively maintain image edges and details, while depressing SAR image noise. The median filter does well in decreasing impulse noise. In this paper, we propose an improved algorithm fusing the enhanced Lee filter and median filter based on spatial filtering of SAR image speckle. The experiment proves it has a good performance in preserving edges and details while filtering images.","PeriodicalId":442320,"journal":{"name":"2013 6th International Congress on Image and Signal Processing (CISP)","volume":"481 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122746677","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}

Passive RFID is a significant research point owing to its advantages. In the meanwhile, anti-collision in active RFID system is inevitable especially in condition of massive tags. Through experiment and analysis, we found out that the ISO/IEC 18000-7 protocol cannot handle the problem well so we put forward a brand new algorithm which is called the slot-controlling method to improve its inventory rate. The conception described in this text is introduced to improve the use of vacant slot and additionally, master and slave reader mechanism can help improve the efficiency of recognition. Finally, we compared the result between the new algorithm and the old one and draw a conclusion that the new slot-controlling method can help improve the inventory rate dramatically under conditions of massive tags.","PeriodicalId":442320,"journal":{"name":"2013 6th International Congress on Image and Signal Processing (CISP)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124232396","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 observations captured by sensors are assumed to be linear instantaneous mixtures of the speech sources in the sensing field. First, a framework is designed for the collection, transmission and separation of mixtures of speech signal in WSNs, and the corresponding algorithm appropriate for blind speech signal separation in wireless sensor networks is selected. We also propose the corresponding sensor selection scheme in WSNs on purpose of energy conservation while ensuring the performance of blind speech signal separation. Experimental results show that the mixtures of speech signal can be effectively separated in the assumed WSN scenario with the traditional blind signal separation (BSS) algorithm we select and the schemes for energy efficiency we propose.","PeriodicalId":442320,"journal":{"name":"2013 6th International Congress on Image and Signal Processing (CISP)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126490196","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}

Three different templates of frontal, right, and left are used to test the algorithm. Experimental verifications are conducted to evaluate performance of the algorithm on RGB, Gray, and YCrCb color spaces.

The model can not only better suppress noise of the image, but also better preserve detailed texture information. However, the order of the fractional differential operator must be determined by a lot of experiments. Therefore, calculating local variance is chosen to express the complexity of the local image texture so as to realize adaptive determination of the order of fractional differentiation. The experimental results show that adaptive fractional partial differential operator not only inherits advantages of TV model, but also better keeps detailed image information. The adaptivity of the model is conductive to its being promoted to practical application.","PeriodicalId":442320,"journal":{"name":"2013 6th International Congress on Image and Signal Processing (CISP)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130596461","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 paper proposes a novel method for radial distortion correction using spherical projection model. First, a series of images of the designed marker board at different imaging orientations are captured by the endoscope. Then, the corners in all images are detected and matched automatically. The spherical model thus can be constructed by fitting the feature points in the projection images. Finally, the relationships of the source image, corrected image and the projection model can be obtained by optimization of the matched features. The process of distortion correction is fully automatic that requires no any human intervention. Experimental results demonstrate that the distortion correction method is very effective, which can achieve a mean RMS error of 0.81 pixel.","PeriodicalId":442320,"journal":{"name":"2013 6th International Congress on Image and Signal Processing (CISP)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130031998","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}
