The previous experiments used point clouds drawn from the Civilian American and European Surface Anthropometry Project (CAESAR anthropometric database provided by the Air Force Research Laboratory (AFRL) Human Effectiveness Directorate and SAE International). This database contains approximately 4,400 high-resolution LIDAR whole body scans of carefully posed human subjects. Features are extracted from each point cloud by embedding the cloud in series of cylindrical shapes and computing a point count for each cylinder that characterizes a region of the subject. These measurements define rotationally invariant histogram features that are processed by a classifier to label the gender of each subject. The recognition results with the tightly control CAESAR database reached levels of over 90% accuracy. A smaller secondary point cloud data set was generated at Wright State University to allow experimentation on clothed subjects that was not possible with the CAESAR data. We present the preliminary results for the transition of classification software using different combinations of training and tests sets taken from both the CAESAR and clothed subject data sets. As expected, the accuracy achieved with clothed subjects fell short of the earlier experiments using only the CAESAR data. Nevertheless, the new results provide new insights for more robust classification algorithms.","PeriodicalId":352567,"journal":{"name":"2012 IEEE National Aerospace and Electronics Conference (NAECON)","volume":"347 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133246820","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, we explore contemporary issues in information fusion design: (1) sensing: from data to information (D2I) processing, (2) reporting: from human computer interaction (HCI) terminals to user involvement (H2U), and (3) the enterprise: from collected to resourced (C2R) information management. D2I reflects the fact that traditional fusion methods focused only on data from a sensor; however, current net-centric applications require intelligent situation awareness that includes processing of information from non-sensor resources for mission effectiveness. H2U demonstrates that completely automated systems are not realizable and that users are required to be involved for efficient decision making. Finally, C2R moves from immediate data collection to fusion of information over an enterprise (e.g,. data mining, database queries and storage, and source analysis for pedigree). By updating the JDL with D2I, H2U, and C2R concepts, they serve as informative themes for future complex information fusion management and system design.","PeriodicalId":352567,"journal":{"name":"2012 IEEE National Aerospace and Electronics Conference (NAECON)","volume":"300 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128621872","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}

WAMI is employed in a variety of applications, including target detection and tracking. However, airborne platform limitations require that WAMI must be compressed to be effectively transmitted and stored. One standard image compression coding system commonly employed with WAMI data is JPEG2000. In order to meet platform and application requirements, JPEG2000 is often used in lossy mode and at high compression rates, leading to serious image degradation. This work studies the effects of image compression on the performance of the Air Force Research Laboratory's (AFRL) Government Algorithms for Tracking Exploitation Research (GATER) tracking algorithm at compression rates of 10:1 to 80:1. Additionally, several image enhancement algorithms widely available in literature, including Contrast-Limited Adaptive Histogram Equalization (CLAHE), High Frequency Boosting and Multiple Scale Retinex (MSR) and a novel approach titled Locally Tuned Sine Nonlinearity (LTSN) are applied to the imagery prior to compression in an effort to improve tracking performance. Results indicate the GATER tracking algorithm is measurably resistant to the effects of image compression up to 40:1 compression. At higher compression ratios, the algorithm is still able to detect the moving objects, however, false alarms become the most performance limiting factor. The enhancement algorithms performance is scene dependant; in some cases boosting overall performance and in other cases showing measurable performance degradation.","PeriodicalId":352567,"journal":{"name":"2012 IEEE National Aerospace and Electronics Conference (NAECON)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131671481","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}
