An important installation problem is to assign a camera schedule with which the system can choose which camera to record its video frames to storage at a certain time. Because of the resource constrained and bandwidth limitation, only a subset of raw video frames can be recorded for a camera. For security concerns, it is expected that the captured frames from the same camera should have equal temporal distance between any two successive ones. If all the distances are not the same, there is jitter. An optimal schedule should minimize the amount of temporal jitter as well as ensure that the jitter between two successive video frames is not greater than a bound. In this paper, the formulation of the scheduling problems is presented. Furthermore, efficient scheduling algorithm is proposed to find feasible schedules given a jitter bound. Experimental results show the efficiency and practicability of the proposed algorithms.","PeriodicalId":142802,"journal":{"name":"2016 IEEE International Conference on Signal and Image Processing (ICSIP)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121959919","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 collects ultrasound signals induced by thermal expansion to reconstruct the conductivity of the object with high spatial resolution and high contrast. Previously reported experimental results on MMTAI only were obtained from the high conductivity samples like the metal. In the study, the experimental system of MMTAI was established with low conductivity phantoms like biological tissues to validate the principle of MMTAI. Different geometrical salinity gel phantom models were designed with the shape of rectangle, triangle and ring, respectively. In the experiment, the gel phantoms were placed in an alternating magnetic field at radio frequency below 20MHz to induce electric field inside the gel phantoms, and thus, corresponding acoustic signals were produced by thermoacoustic effect, meanwhile acoustic signals were detected by the transducer. The experiments show that the acoustic signal can reflect the location information of the object. Furthermore, experiments may be improved to image the conductivity of the object on MMTAI.","PeriodicalId":142802,"journal":{"name":"2016 IEEE International Conference on Signal and Image Processing (ICSIP)","volume":"96 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126702918","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 localization bias caused by constant TDOA measurement bias is analyzed. It can be proved that this localization bias can be auto-eliminated when the sum of baseline orientation vectors that correspond with all TDOA measurements equals to zero. Otherwise, in order to mitigate the localization bias caused by TDOA measurement bias, a recursive nonlinear least squares(NLS) based self-calibrating localization method is proposed where the TDOA measurement bias and source position are estimated jointly. The Cramér-Rao lower bound (CRLB) of the proposed method is also analyzed. Simulation results show that the performance of the proposed method can be close to the CRLB under moderate Gaussian TDOA measurement noise.","PeriodicalId":142802,"journal":{"name":"2016 IEEE International Conference on Signal and Image Processing (ICSIP)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126829105","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}

Different types or production batches of EPD films need different driving waveforms; even in the same device, different driving waveforms are required under different environments to guarantee the display quality. Therefore, the design of driving waveforms is always the core of EPD display technology. The image displayed using 4 gray levels is not sufficiently satisfactory. To improve the display quality of EPD, the design of driving waveforms with 16 gray levels has been proposed. This paper presents a stable and adaptive design system, which may better design driving waveforms with 16 gray levels and guarantee the required display quality. Simultaneously, the design steps are simplified, and the work efficiency is improved.","PeriodicalId":142802,"journal":{"name":"2016 IEEE International Conference on Signal and Image Processing (ICSIP)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121523068","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 a double transducer measurement system, when impulses are loaded to transmitter with reflection and refraction of sonic, the receiver nearby will receive echoes immediately, which will leads to a period of time that can't be measured. If an object is near the transducer, the receiver gets stronger echoes reflection from the object than reflection and refraction from the transmitter. By distinguishing the amplitude of echo waves in blind area, we figured out the distance between the object and the transducer.","PeriodicalId":142802,"journal":{"name":"2016 IEEE International Conference on Signal and Image Processing (ICSIP)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130618555","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}

However, the recognition of cell patterns requires manual annotation by experienced physicians, which is subject to inter-observer variability. Therefore, an automatic diagnosis system is desirable. As the crucial pre-processing step for cell pattern recognition, the performance of cell segmentation is crucial. In this paper, a novel adaptive local thresholding approach is proposed to solve the issue. The approach divides cell images into overlapping sub-images and applies adaptive threshold estimator to each of them. The ICPR 2014 HEp-2 cell datasets are employed to assess the segmentation performance of our framework. The results show that the system achieves an average segmentation accuracy of 66.95%, which outperforms the typical thresholding approaches.","PeriodicalId":142802,"journal":{"name":"2016 IEEE International Conference on Signal and Image Processing (ICSIP)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130874234","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}

For the ease of visual comprehension by human, it is preferred that the logo should be big, if possible. A logo-embedding scheme, which is referred to as module displacement, is proposed. In module displacement, the data modules that are corrupted by the logo are moved to hide behind those modules that are not corrupted by the logo. Moreover, the problem of decoding a logo-embedded QR code posted on a plane or a cylinder is addressed. In both cases, the QR image as captured by a camera is distorted. Therefore, some operation needs to be performed to rectify the deformation.","PeriodicalId":142802,"journal":{"name":"2016 IEEE International Conference on Signal and Image Processing (ICSIP)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131156961","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}

One popular problem of ECC implementation is the trade-off between high coding-gain and decoder's complexity.

Simulation results show that very high coding-gain and reduced-complexity are achieved.
