Methods in the literatureeither follow a direct approach, by first detecting people andthen counting them, or an indirect approach, by establishinga relation between some easily detectable scene featuresand the estimated number of people. The indirect approachis considerably more robust, but it is not easy to take intoaccount such factors as perspective or people groups withdifferent densities.The proposed technique, while based on the indirect approach,specifically addresses these problems; furthermoreit is based on a trainable estimator that does not requirean explicit formulation of a priori knowledge about the perspectiveand density effects present in the scene at hand.In the experimental evaluation, the method has beenextensively compared with the algorithm by Albiol et al.,which provided the highest performance at the PETS 2009contest on people counting. The experimentation has usedthe public PETS 2009 datasets. The results confirm that theproposed method improves the accuracy, while retaining therobustness of the indirect approach.","PeriodicalId":415758,"journal":{"name":"2010 7th IEEE International Conference on Advanced Video and Signal Based Surveillance","volume":"139 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132431058","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}

These systems workwell in controlled conditions, but often fail when lightingis poor, or environmental effects such as shadows, dust orsmoke are present. Thermal spectrum imagery is not as susceptibleto environmental effects, however thermal imagingsensors are more sensitive to noise and they are onlygray scale, making distinguishing between objects difficult.Several approaches to combining the visual and thermalmodalities have been proposed, however they are limited byassuming that both modalities are perfuming equally well.When one modality fails, existing approaches are unable todetect the drop in performance and disregard the under performingmodality. In this paper, a novel middle fusion approachfor combining visual and thermal spectrum imagesfor object tracking is proposed. Motion and object detectionis performed on each modality and the object detectionresults for each modality are fused base on the currentperformance of each modality. Modality performance is determinedby comparing the number of objects tracked by thesystem with the number detected by each mode, with a smallallowance made for objects entering and exiting the scene.The tracking performance of the proposed fusion schemeis compared with performance of the visual and thermalmodes individually, and a baseline middle fusion scheme.Improvement in tracking performance using the proposedfusion approach is demonstrated. The proposed approachis also shown to be able to detect the failure of an individualmodality and disregard its results, ensuring performance isnot degraded in such situations.","PeriodicalId":415758,"journal":{"name":"2010 7th IEEE International Conference on Advanced Video and Signal Based Surveillance","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123891171","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}

Whilecommon approaches for appearance based person reidentificationin the visible spectrum acquire color histograms ofa person, this technique is not applicable in infrared for obviousreasons. To tackle the more difficult problem of personreidentification in infrared, we introduce an approachthat relies on local image features only and thus is completelyindependent of sensor specific features which mightbe available only in the visible spectrum. Our approachfits into an Implicit Shape Model (ISM) based person detectionand tracking strategy described in previous work.Local features collected during tracking are employed forperson reidentification while the generalizing appearancecodebook used for person detection serves as structuringelement to generate person signatures. By this, we gain anintegrated approach that allows for fast online model generation,a compact representation, and fast model matching.Since the model allows for a joined representation ofappearance and spatial information, no complex representationmodels like graph structures are needed. We evaluateour person reidentification approach on a subset of the CASIAinfrared dataset.","PeriodicalId":415758,"journal":{"name":"2010 7th IEEE International Conference on Advanced Video and Signal Based Surveillance","volume":"111 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128948026","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}

To addressthis aspect, both rule-based (aka. extensional) and statebased (aka. intensional) approaches have been adoptedfor situation or visual event analysis. The former providesflexible expressive power and computational efficiency buttypically allows only one directional inference. The latteris computationally expensive but allows bidirectional inter-pretation of conditionals by treating antecedent and conse-quent of conditionals as mutually relevant states. In visualsurveillance, considering the varying semantics and poten-tially ambiguous causality in conditionals, it would be use-ful to combine the expressive power of rule-based systemwith the ability of bidirectional interpretation. In this paper,we propose a hybrid approach that, while relying mainly ona rule-based architecture, also provides an intensional wayof on-demand conditional modeling using conditional op-erators in subjective logic. We first show how conditionalscan be assessed via explicit representation of ignorance insubjective logic. We then describe the proposed hybrid con-ditional handling framework. Finally we present an exper-imental case study from a typical airport scene taken fromvisual surveillance data.","PeriodicalId":415758,"journal":{"name":"2010 7th IEEE International Conference on Advanced Video and Signal Based Surveillance","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129013624","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}

Meanwhile, the actionlocalization is done using Dynamic Conditional RandomFields developed to incorporate the spatial and temporalstructure constraints of superpixels extracted aroundthose features. Each superpixel in the video is defined by theshape and motion information of its corresponding featureregion.
